The Energy Fight Coming to the Senate

Monday, July 12th, 2010 by

“This is such an important time for the industry,” was the first thing said to me by Acciona Energy North America CFO Susan Nickey, who was fresh from meetings in Washington, D.C.

It’s an important time because the Gulf oil spill has revived hope for the once lost-cause energy-climate legislation — and because the renewable energy industries are desperately in need of such legislation.

After sustaining growth in 2009, some of the renewables’ most important incentives are set to expire at the end of this year. Nickey’s meetings with Republicans have revealed that there are Republican votes for new legislation.

“There is bipartisan support both on the Senate and House sides to pass a Renewable Energy Standard [RES] to create long-term growth and to also extend the grant-in-lieu of the ITC program to maintain last year’s expansion,” Nickey said. But, she stressed, only if the administration and the Democratic leadership forego action on greenhouse gas emissions.

A national RES would require regulated U.S. utilities to obtain 20 percent to 25 percent of their power from renewable sources by 2020 or 2025. The Treasury’s grant program allows unused tax credits to be exchanged for federal grants.

Nickey is in a unique position to see the legislative dilemma clearly. Because Acciona, one of the biggest players in U.S. solar and wind, has a major manufacturing facility in Iowa, Nickey has had meetings with the staffs of Iowa Democratic Senator Tom Harkin and Iowa Republican Senator Chuck Grassley, as well as other Republicans. Iowa is a wind powerhouse and one of the first states to pass an RES. But it is also a conservative state and not inclined toward climate change-fighting cap-and-trade legislation.

The cap-and-trade plan would limit the greenhouse gas emissions (GHGs) emitted by major power producers, which many climate scientists have pinpointed as the leading cause of global climate change. The measure would also create a market mechanism to facilitate the emitters’ ability to meet their caps. Seen by many environmentalists as vital to the fight against climate change, cap-and-trade has been successfully branded as an overly complicated stealth tax by its opponents.

What Nickey learned in D.C. is the very significant news that Republican senators might support energy-only legislation and an RES. Grassley, she said, has long supported the wind industry and “helped put together the production tax credit [PTC] a long time ago.”

The PTC is the key incentive with which the wind industry built its 2005-to-2009 “boom,” but it is a short-term incentive whose withdrawal has been held responsible for causing the wind industry’s three “bust” years (2000, 2002, and 2004).

Having a long-term incentive like the RES will thrill the renewable energy industries, but some environmental groups will not be pleased if Congress is unable to pass climate change provisions along with it.

“The Bingaman bill would do more harm than good, by promoting more off-shore and ultra-deepwater oil and gas drilling in the Gulf, as well as other dirty energy industries such as nuclear power, coal with carbon sequestration and ‘biomass’ incineration,” according to Mike Ewall of the Energy Justice Network. “The bill’s main selling point — the Renewable Electricity Standard (RES) — does nothing that the similar existing policies in 30 states would not already accomplish and it is riddled with loopholes. We support addressing climate change with good energy policy that isn’t full of dirty energy subsidies, but our corporate-controlled Congress is not up to the task.”

“A bundle of energy policies alone cannot accomplish the three-fold task of curbing pollution, creating jobs, [and] cutting our dependence on foreign oil,” wrote David Doniger of the Natural Resources Defense Council (NRDC). “An integrated bill will reduce global warming pollution, while a piecemeal ‘energy only’ bill could make carbon emissions worse.”

But Nickey, fresh from D.C. and impressed with the Republican senators’ insistence that there are not enough Senate votes for a bill with climate provisions, nevertheless sees something very valuable in the compromise measure.

Acciona has, since 2006, invested a billion dollars in the U.S. wind and solar sectors and has created more than 2,300 direct and indirect jobs. It sources more than 60 percent of its turbine components domestically and could grow U.S. manufacturing much more with the extension of the Treasury grant program and the long-term RES that may be within the reach of this divided Congress, despite election-year tensions.

“We’re supportive of carbon legislation,” Nickey said. “But it’s a complicated policy.”

“They,” meaning the Republicans she met with, “were supportive of a bill that had a Renewable Energy Standard like the Bingaman bill. And we also focused on having not just 20 percent or 25 percent by 2020 or 2025, but also [implementing] an increase in the Renewable Energy Standard in the near term, the 10 percent by 2012, because it’s about creating momentum, investment and jobs today.”

Congress-watchers say the floor fight must happen by the week of July 19 if it is going to happen at all before the August recess. Nickey said the key will be whether the Democratic leadership is willing move off comprehensive carbon legislation.

To Nickey, such legislation would be no defeat. “In the U.S. market, we start out with wind comprising less than two percent of our energy portfolio,” Nickey concluded. “With a mandate to get 25 percent of our energy from renewables by 2025, we’ll create a large and growing industry opportunity.”

CNET’s Best of CTIA Awards

Friday, March 26th, 2010 by

Another CTIA has come to an end, so it’s time for CNET to pass out our Best of CTIA awards. We had to make a tough choice this year and break away from our traditional categories; because most of the major handset announcements in Las Vegas this year were smartphones (you can blame Android for that) we consolidated the traditional Best Phone and Best Smartphone categories into a category for Best Phone, plus a runner-up. We also couldn’t find a worthy nominee for Best Software/Service so we did away with that category completely. So now, on to the winners.

Best Phone
HTC Evo 4G
Yes, this is a bit obvious, but we have to give credit where it’s due. Not only is it America’s first 4G phone, but the Android-powered Evo is also a gorgeous device. The display is stunning, it offers oodles of features–we particularly love its capability to act as a hot spot for up to eight devices–and it is really fast.

The Evo is still in early form, but we like what we see so far, from the interface to the hardware to the performance. Sure, we know that it’s really meant for people in a Sprint WiMax market, but even 3G people should get a kick out of this device. Sprint promises the Evo 4G this summer, though we don’t yet know a price or any service plan details. And, in that regard, our only advice is, “Sprint, don’t screw it up.”

Runner-up
Samsung Galaxy S
Samsung rarely lets us down when it comes to a tech trade show, and CTIA 2010 was no exception. The Samsung Galaxy S is a worthy device all around. We’re optimistic about the Social Hub, we love the design and AMOLED display, and the feature set includes messaging, multimedia, a personal organizer, and communication. We also like that it runs Android 2.1

The Galaxy S would have given the Evo 4G a run for its money for the the top title if only we knew more about U.S. availability. Samsung says it will be out by this summer, but we don’t know in what form. We’ll be waiting to see what happens next.

Best Accessory
BlueAnt A1
The BlueAnt T1 is our pick for best accessory thanks to its promise of superior wind-noise performance; it claims to deliver clear audio in wind speeds up to 22 miles per hour. It has a text-to-speech technology that will read out incoming caller IDs and text messages, plus it’s also one of a few durable headsets, with a special protective case that makes it great for the outdoors enthusiast.

BlueAnt Launches Rugged T1 Voice-Controlled Headset, Android Application That Speaks Text Messages

Monday, March 22nd, 2010 by

BlueAnt’s trademark seems to be voice-controlled Bluetooth headsets, so we were none too surprised when it announced the T1, another voice-controlled earpiece that lets users answer or ignore calls with voice commands. But we were more intrigued by its second announcement, an Android app that speaks text messages into your Bluetooth headset.

The free BlueAnt Android Q1 application works with two BlueAnt headsets: the V1 and, yes, the Q1, both of which are voice-controlled. Unfortunately, it’s only compatible with Android 2.0 and higher, which means it won’t work with most phones, save for, say, the Droid and Nexus One. When you do receive a text message, the app will recite the text, although it will announce the senders by their phone number, not their name. Curious? It’s available today in Android Market.

The T1, meanwhile, ushers in a new wind noise reduction technology called Wind Armour, which promises clear sound amid winds as fast as 22 miles per hour. Its design, including a silicon layer that covers the whole headset, is more rugged than most headsets’. It’s also the first voice-controlled headset in BlueAnt’s lineup to announce the names of callers. Other specs include A2DP streaming for music and turn-by-turn directions from your phone, the ability to pair with two devices at once, 6 hours of talk time, and 120 hours of standby. Look for it in May for a reasonable list price of $79.99.

Bluetooth 4.0 to Reach Devices in Fourth Quarter

Wednesday, March 3rd, 2010 by

The Bluetooth 4.0 wireless specification could start to appear in devices such as headsets, smartphones and PCs by the fourth quarter, the Bluetooth Special Interest Group said on Wednesday.

The new specification will be able to be used in lower-power devices than previous versions of the technology, including watches, pedometers, smart meters and other gadgets that run on coin-cell batteries, said Michael Foley, executive director of the Bluetooth SIG standards-setting organization. Previous versions of Bluetooth could only go into devices with triple-A or larger-capacity batteries.

Bluetooth 4.0 includes a low-energy specification for transmitting small bursts of data over short ranges, in addition to the high-speed data transfer capabilities introduced with Bluetooth 3.0 last April.

More wireless capabilities are being added to gadgets like cameras, portable game players and tablet PCs to help them communicate with other devices, said Charles Golvin, principal analyst at Forrester Research. Bluetooth 4.0 could be used to let those devices exchange low-level information without using much energy, he said.

“These protocols are designed to be very efficient because they are delivering small bits of data,” Golvin said.

Despite the low-power option, users will notice only nominal battery-life improvements for long-range or continuous data communication, Foley said. Bluetooth 4.0 radios will consume roughly the same amount of power as Bluetooth 3.0 radios when used to sync smartphones with laptops or listen to music with wireless headphones, he said.

The new specification will carry the high-speed Wi-Fi feature introduced with Bluetooth 3.0. That allows devices to jump onto Wi-Fi 802.11 networks, where it can transfer data at up to 25Mbits per second.

Bluetooth competes with wireless technologies such as WiBro, UWB (Ultra Wideband) and Wi-Fi. But Bluetooth 4.0 is better-suited for short-range communications, as competing technologies expend a lot of energy to transmit data over similar distances. “They’d be like pulling out a cannon to kill a mouse,” Golvin said.

The Zigbee wireless specification is another alternative to Bluetooth 4.0, but Bluetooth has the advantage of being widely deployed across devices, Golvin said. That gives it a head start over competing technologies.

Bluetooth is also an open standard, while most competing low-level technologies tend to be proprietary, Golvin said. For example, The Nike + iPod Sport Kit uses a proprietary technology to send exercise data from a shoe to an iPod or iPhone.

Dealing with LED Heat

Monday, March 1st, 2010 by

Light-emitting diodes (LEDs) don’t like heat. Heat shortens their lifetimes. It also damages brightness, ruins efficiency and diminishes color.

“Heat is death to an LED,” says Joe DeNicholas, Lighting Business Unit director for National Semiconductor. “There’s widely published data suggesting that if you keep the junction temperature of an LED at about 100 degrees Celsius, it will last for 80,000 hours. But if you let it go to, say, 135 degrees Celsius, the lifetime drops down to about 20,000 hours. That’s why we have to keep them cool.”

Keeping them cool, however, is no simple task. In the past decade, LED current levels have soared. Whereas 20 mA was typical a few years back, 1A is commonplace today. Similarly, power levels have skyrocketed from milliwatt levels a few years ago to more than a watt today. In some industries power levels are said to be doubling every three to six months.

“The old LEDs never required cooling,” says Barry Dagan chief technical officer of Cool Innovations, a maker of heat sinks. “But when you’ve got two watts of dissipated power, you have to have cooling. And now we’re starting to hear talk of power levels at 10 watts, 15 watts and more.”

So how’s an engineer supposed to cool a little LED that may need to dissipate a couple of watts? Answers are many. Electronics manufacturers have developed drivers that can back off the current when the junction temperature rises too high or when the LED is illuminating an unoccupied room. Materials experts have created metal-clad substrates that draw heat away from the LED. And heat sink manufacturers are finding new and innovative ways to move heat into the surrounding air.

“The engineer has to figure out the path that takes the heat from the LED junction out to the ambient air,” says Joe Jablonski, applications engineering manager for Osram Opto Semiconductors, an LED manufacturer. “That path is your thermal system.”

Go to the Source

So if LEDs require such care, why go to the trouble? Why not use an incandescent bulb? Engineers say there’s good reason. LEDs offer exceptionally long life, making them ideal for applications where it’s difficult to change a bulb. Then there’s efficiency. LEDs deliver a lot of light for little power. Although reliable figures for lumens-per-watt are difficult to pin down, the difference between an incandescent and an LED is vast. By some accounts, LEDs offer about 120 ℓm/W, while incandescents hover between 10-15 ℓm/W.

“There’s no doubt about it,” DeNicholas says. “The LED is the most efficient controllable light source ever created.”
To be sure, though, LEDs still carry higher costs. “There has to be an overwhelming need, other than efficiency, to use an LED,” says Tom Morris, applications engineering manager for TT Electronics’ IRC Div. “The price you pay per lumen of output is still much more than what you’d pay with a conventional light bulb.”

Still, the number of applications is growing rapidly. Between 1999 and 2009, prices dropped to about one-third of what they had been, making it possible to use LEDs in a wide variety of special projects, including such notable applications as the driver-customizable Ford Mustang interior and the massive 12-million-light Walgreens sign in New York’s Times Square. Experts say LED use also continues to increase in medical equipment, handheld electronics, architectural lighting, parking garages, street lights, television backlighting, signage, vehicle interiors and even automotive head lamps.

The key to making it happen is thermal management, say experts. “With the development of high-brightness LEDs in one-watt packages, there’s enough heat being produced so that you now have to get rid of it,” Morris says. “That’s the only way you’re going to attain the luminosity and reliability that you need from your LED light source.”

The place to start managing heat is at the source, engineers say. Electronics manufacturers such as Texas Instruments (TI) and National Semiconductor are doing it with the development of smart LED drivers. TI, for example, has rolled out a product known as UCC28810SIMPLEDrive, capable of controlling current and dimming LED illumination. By integrating the intelligence of TI microcontrollers, the driver can monitor junction temperature or employ a feature known as intelligent occupancy sensing.

“It senses if there are occupants in the room, and it turns on or off the lights or it dims the lights,” says Peter Di Maso, product marketing manager with TI’s Power Management Business Unit. The company also enables users to program the LED’s operation to keep temperatures at a desirable level. Engineers can set the driver to gradually cut back on electrical current until the unit reaches a prescribed shut-off temperature.

“If we start to detect it’s getting hot, we decrease the current,” says DeNicholas of National Semiconductor. “When we decrease the current, it lowers the light output, but it also decreases the power dissipation, so we can keep the LEDs in a safe operating region.” (National Semiconductor also offers help for designers with its WEBENCH® LED designers tool suite.)

Spreading the Heat

Still, heat happens. And when it does, the entire LED system has to be able to dissipate it. Typically, heat travels a circuitous path, gradually exiting the LED through its electronic packaging, moving into a printed circuit board and across a dielectric layer, and then onto a heat sink where it is transmitted into the surrounding atmosphere. In some cases, applications engineers also employ blowers or other active devices to help push the heat away from the LED assembly.

“It’s very similar to water flow,” DeNicholas says. “You don’t want to resist it. You want the heat to travel from its generated source to where it is being dissipated, as smoothly and fluidly as possible.”

Materials experts, such as The Bergquist Co. and TT electronics’ IRC Advanced Film Div., create substrates that can quickly transfer heat away from the LED’s base. Bergquist’s Thermal Clad Insulated Metal Substrates (IMS) provide an alternative to the commonly used and inexpensive FR-4 material, which consists of copper laminated to a glass-epoxy board. In contrast to FR-4, Thermal Clad IMS is a thin, thermally conductive layer bonded to an aluminum-copper substrate for the expressed purpose of heat dissipation. The layer combines electrical isolation with high thermal conductivity, while bonding the base metal and circuit foil together. The bottom line for users is that the metal-clad substrate quickly transfers heat to the aluminum base plate, thus improving the LED’s performance.

“The LEDs are placed on top of the substrate using regular surface mount technology,” says Justin Kolbe, a senior research and development engineers for The Bergquist Co. “Conduction to, and through, the thick metal layer is very good.”

Similarly, TT electronics’ IRC Advanced Film Div. has rolled out a substrate technology known as Anotherm, which consists of an aluminum alloy substrate, a thin dielectric layer and a screen-printed conductor atop the dielectric. “Because of the high thermal conductivity that the base aluminum substrate offers, in many cases the Anotherm board eliminates the need for additional heat sinks,” says Morris of TT Electronics’ IRC Div.

Creating Air Flow

In some cases, however, heat sinks, fans and other devices may be needed. In those cases, engineers typically try to employ natural convention first, and forced convection (fans and other active devices) second. “In the natural convection mode, if you just move the air slightly, you can increase cooling by a factor of as much as ten,” says Dagan of Cool Innovations. “If you run a fan at low speeds, you can improve your cooling even more, but many people don’t want fan noise in their LED applications.”

Cool Innovations has developed an innovative way to boost the cooling of naturally convected systems. The company’s flared pin heat sinks depart from the conventional by employing thermally conductive pins that are splayed outward. Because the flared pins incorporate significantly wider spacing than conventional straight pins, they feature low friction between the air and the heat sink.

“By nature, there’s a limit to how much heat you can dissipate by the natural convection mode,” Dagan says. “But with the flared design, we’re tricking the heat sink. By flaring the pins outward, we’re using free space and the distance to adjacent pins is greater. So we’re optimizing the surface area and the distance between the pins.”

Dagan says the flared pin design dramatically aids heat dissipation. He adds, however, that some systems still need a fan or other type of active device when power generation reaches high levels. For those applications, Cool Innovation also offers “pin-fin fansinks” that embed a fan in the heat sink’s pin array. The fansinks, designed for applications that are restricted in height but need substantial cooling power, generate 6.1 cubic ft of air flow per minute.

Similarly, Nuventix Inc. markets a product know as the SynJet – a synthetic jet that uses a diaphragm to cool the region around the LED. The device works by activating an electromagnetic driver, which causes the diaphragm to oscillate, thus pulling the surrounding air into the device’s housing. Rapid cycling of air in and out of the housing creates turbulent pulsating air jets that can be directed to precise locations where cooling is needed.

Experts say forced convection will continue to be a necessity in some applications. “There is a class of LEDs where the users don’t care about noise,” Dagan says. “In applications where replacement of bulbs is costly, such as in skyscrapers, or where LEDs are hard to reach, it makes sense to have a small fan on top. That way, you increase the life of the device.”

More Heat to Come

With average LED power levels doubling every few months, engineers say the number of potential LED applications will balloon, as well. New electronic products can now drive 40 LEDs at once, and experts predict future chips will soon be able to drive as many as 80 LEDs at a time. Moreover, new research suggests that future LEDs of 180-200 ℓm/W may be only two years away. That’s why engineers in the auto and consumer electronics industries are talking about more widespread use of LEDs.

“LEDs have moved from cheap indicator lights to much more sophisticated applications over the last few years,” says Kolbe of Bergquist. “You’re going to see them in architectural and artistic applications and in automotive head lamps and streetlights more than ever before.”

But as power levels rise to 10W and possibly even 20W, engineers know there will be more heat and they’ll need new ways to manage it.

“It’s not like an incandescent light,” says Di Maso of  TI. “Incandescent bulbs eliminate their heat through radiation, whereas with LEDs it’s more of a mechanical issue. But with the efficiency of LED systems increasing as they are, that’s a problem worth solving.”

Clean Energy Shows Spark

Clean Energy Shows Spark
By KEITH JOHNSON

The clean-energy industry is poised for record growth in the U.S., with big companies expecting to invest billions of dollars, despite Washington’s failure to enact limits on greenhouse-gas emissions.

Areva SA, a world leader in nuclear power, this month announced it is taking a leap into U.S. solar power, buying California solar-equipment maker Ausra Inc. The French energy company said demand for solar plants is likely to jump by 20% a year over the next decade and that it plans to be a leader in what it called an “attractive and growing market.” Terms of the deal weren’t disclosed.

Many politicians and environmentalists had argued that a clean-energy revolution requires passage of a cap-and-trade program that limits greenhouse-gas emissions and provides a market for trading on the ability to meet the caps. The idea is that such a system would make traditional energy sources more expensive and cleaner energy more appealing.

But that doesn’t seem to be the case. Existing programs to support clean energy, combined with the prospect that Congress will pass an energy and jobs bill, have many analysts projecting a banner 2010.

Natural gas could sap near-term enthusiasm for renewable energy and there’s concern that government incentives could have only short-term effects.

But the biggest names in renewable energy—such as General Electric Corp., Iberdrola SA, NextEra Energy Resources, First Solar Inc. and Horizon Wind Energy—still say they are confident of a strong year, even without the prospect of climate-change legislation in Congress.

NextEra, a unit of FPL Group Inc. and the largest wind-farm operator in the U.S. by capacity, recently purchased a trio of wind farms from Babcock & Brown Infrastructure Group. NextEra, which is on the lookout for further wind-power acquisitions, plans to add one gigawatt of wind power this year, in optimum conditions roughly the capacity of a nuclear power plant.

Spain’s Iberdrola, the world’s largest renewable-energy company by capacity, was the biggest recipient of U.S. government grants for clean-energy projects last year, receiving $570 million, and expects to receive $400 million more this year to spur wind-farm development.

Clean-energy companies say it would have taken years before the penalties in cap-and-trade legislation would have sparked development. “We still support cap-and-trade, but the price on carbon emissions we would expect to see simply isn’t sufficient to make a difference to our industry,” says Don Furman, senior vice president for development, transmission, and policy at Iberdrola Renovables, the company’s clean-energy unit.

The clean-energy sector last year braced itself for trouble after the credit crunch and the recession slammed business investment broadly. But the U.S. government’s stimulus package, which included cash grants for clean-energy projects, turned the year into a record breaker. The American wind-power industry, for example, installed nearly 10 gigawatts of new turbines, keeping the U.S. the world leader by capacity. While that represents less than 2% of U.S. energy generation it was more than the entire installed capacity in 2005.

Bloomberg New Energy Finance, a clean-energy consulting firm based in London, figures world-wide investment in clean energy could reach $200 billion this year, easily topping the record of $155 billion set in 2008.

The U.S. is at the forefront. The Department of Energy still has almost $30 billion in stimulus grants left to spend this year.

Meanwhile, the Obama administration’s budget calls for a jump in federal loan guarantees for new energy projects. And Congress is considering, as a means to create jobs, legislation to establish renewable-energy targets decades into the future.

That has renewable firms champing at the bit. Energias de Portugal SA’s Horizon plans to invest $4 billion in the U.S. through 2012. GE, which dominates the U.S. market for wind turbines, expects revenue in its clean-energy division to rise to $25 billion this year, up from $17 billion in 2008. Both companies, like Iberdrola, cite existing support for clean energy as a big reason the U.S. is such an attractive market.

The companies do have concerns, however. Natural-gas prices are relatively low, which makes wind farms less economically competitive. And many companies worry that the short-term incentives for clean energy, especially the cash grants, could simply drive firms to accelerate already planned investment in clean energy rather than create new investment, much as the “cash for clunkers” program accelerated future sales of automobiles.

That’s why a lot of firms are still pushing for more long-term support, such as the federal renewable-energy targets under consideration in the Senate. Clean-energy lobbyists made a plea for Washington to pass energy legislation that will prop up their businesses.

“There’s so much activity now because of the uncertainty over future incentives,” says Pete Duprey, chief executive of Acciona North America, a unit of Spain’s Acciona SA, a big player in wind power, solar power, biofuels and water treatment.

You Don’t Need a Weatherman to Know Which Way the Wind Blows

You Don’t Need a Weatherman to Know Which Way the Wind Blows

But we do need a national energy policy to stimulate wind, solar, and other renewable fuel projects, says Acciona Energy North America’s CFO, Susan Nickey.

David M. Katz – CFO.com | US

You might not expect to spot a finance chief on Capitol Hill, jawboning senators and representatives. Yet that’s where Susan Nickey of Acciona Energy North America found herself on February 11, just two days before Congress passed the American Recovery and Reinvestment Act, better known as “the stimulus bill.” The only CFO among a group of wind-power advocates, she was holding forth on the need to spur capital investment in renewable energy.

Unlike most other finance chiefs, Nickey feels that an important part of her job consists of making things happen in Congress. Thus, she’s found herself nose to nose with the likes of California Sen. Barbara Boxer and has joined a number of policy-oriented committees of the American Wind Energy Association aimed at boosting the financing of renewable-energy projects. “The biggest challenge and the most difficult issue that I need to work on is to get Washington to think about the energy policy and the legislation in terms of its having has to work for the capital markets. Our work is so capital intensive,” she says.

Her main reason for such work: a major source of project financing isn’t up to producing the growth the industry needs to stay viable. Up until now, wind, solar, and other alternative-energy efforts have been funded heavily in the United States via tax credits given to investors in such projects. Investment banks like JPMorgan and GE Capital, which tend to report huge profits, are in the market for deals that will provide them with tax credits to slim down their tax liabilities.

In contrast, project developers and owners like Acciona, the Spain-based parent company of Acciona Energy North America, don’t have a big-enough U.S. tax base to make efficient use of the tax credits.

Thus investment bankers and big commercial banks like Citigroup have been moved to take equity stakes in tax-favored renewable energy projects. But the amount of funding unleashed by a tax-based national energy project is limited, especially since the nation’s investment banking sector was walloped by the global financial crisis, Nickey notes. What’s more, the current tax-oriented financing system for renewable energy is “overly complex, restrictive and [provides] a too-small pool of available capital,” she says.

Currently, she’s most worried that the U.S. Treasury Department won’t continue supplying the cash refunds mandated by the stimulus bill for qualified renewable energy facilities. The amount of a grant generally equals that of the investment tax credit the owner otherwise would have been eligible for (usually 30% of the qualified cost of the project).

She sees such funding as a “bridge” from a system based on tax incentives to “the enactment of a stable, long-term energy policy to support renewable energy growth and attract capital investment through the larger capital market pools available for energy in the U.S.” From a CFO’s perspective, she says, she feels that such a policy must provide investors with “a predictable minimum economic return stream to attract long-term capital.”

The bulk of Nickey’s job at Acciona Energy North America is taken up with project finance issues — something she knows a good deal about, having worked for 20 years in commercial and investment banking experience, including 15 years in the renewable energy sector. In fact, she made the transition to CFO three years ago, working as an investment banker for Mesirow Financial on Nevada Solar One, a project that Acciona had become involved in that employs concentrated solar energy. She proceeded to start up the finance operations of the European company’s new Chicago-based North American unit from scratch.

Nowadays, she spends the bulk of her time wrapping up financing on such deals as the Red Hills Wind Farm in Oklahoma, a project Acciona closed with $100 million in “tax-equity” financing and $65 million in debt financing on August 21. But as the finance chief for not only Acciona Energy North America, but for the conglomerate’s separate U.S. wind and solar power subsidiaries as well, she’s responsible for the usual run of a CFO’s duties: accounting, financial planning and analysis, asset management, compliance, and risk management.

Indeed, making use of what seems like a wellspring of energy, she hasn’t taken very many vacation days in the last three years, Nickey told CFO Deputy Editor David M. Katz and Senior Editor Marie Leone in an interview in New York on October 13. An edited version of the conversation follows.

How is Acciona North America positioned in terms of the parent corporation?
The strategy is for 70% of the growth to be international, with the North American market being the primary growth market. Given the size of the North American market for renewable energy today — in which about 2% of our power is in renewables — we have a huge opportunity to be a good chunk of that 70%.

The North American operations really kicked off about three years ago. I was the financial advisor for them on Nevada Solar One, and they looked at that project as a key entree into the marketplace. They then made a commitment to open a wind-turbine manufacturing facility, and then three were built, for a total of over 500 megawatts. That’s three huge wind projects. We’ve been in a start-up to high-growth mode in the last three years.

What’s your current sales figure for North America?
We haven’t published the North American sales figures externally yet, but we will. We’re a private company, so we publish things on a consolidated global basis instead of just for North America. But you know, we’ve gone from a couple of million in revenues to over a couple hundred million in revenues. I can also say that in the past three years, we have added 546 megawatts of wind energy (410 in the United States, 136 in Canada) and 64 megawatts of solar energy, for a total of 610 MW. [In comparison, U.S. nuclear power plants have net summer capacities of between about 500 and 1300 megawatts.]

How do you finance a typical project?
What drives the market in the U.S is the tax incentives. For example, I financed Nevada Solar One with tax investors and debt, and it’s the same thing for our wind projects. When you look at individual wind projects, typically the tax credits have driven the majority of the capital structure — say 50% to 60% — with traditional project debt being another 20%, and 20% in sponsored equity from Acciona.

How did you move from investment banking into being a CFO?
As an investment banker for Nevada Solar One, I was brought on as a financial advisor to work with the State of Nevada and come up with a structure that would build an almost $300 million project. My role was to look at the development and the contracts, and to produce something that the markets would invest in, up-front, as a 25-to-30-year asset [on their books]. Acciona came in and said they wanted to invest in the United States and were willing to launch. But from across the seas, they said to me, “you’re the person on the spot that helps give us comfort that the pieces, the market, and the tax investors are there.”

So I helped put together the whole package, with a bow on it. I prepared the due diligence for Acciona to come in as the equity investor and gave them the comfort that we were going to have the long-term takeout. As we closed that project, they continued to spend a lot of time in North America and decided to open an office in Chicago and continue to build the human capital infrastructure to leverage what they had. They became confident that U.S. financial investors would step up and invest in these projects. I was with Mesirow Financial and then I joined Acciona as their CFO as we were closing that project.

What exactly is a “tax-equity investment”?
An equity investment in which the return is tax-benefit-driven, rather than cash-driven. In the case of renewable energy investments, a tax-equity investment would be motivated primarily by the production tax credit or investment tax credit and accelerated depreciation. The tax-equity investor market in renewables has primarily been comprised of institutional equity investors, typically large financial institutions such as JPMorgan and GE Capital. They have a significant tax base to efficiently use the tax incentives that developers and owners of renewable projects, such as Acciona, lack.

An investment credit is the same concept as a tax-equity credit. They get a dollar-for-dollar reduction in their tax bill today by making this investment. Let’s use a round number: there’s a $100 million a tax credit for making a $300 million investment in a solar project. You can allocate it through a partnership.

How many partners does a typical project have?
Usually you have financial institutions like the JPMorgans or the Citibanks. The reason for that is that banks don’t have manufacturing or other depreciation [that they can claim for tax purposes]. They’re typically very profitable, but they have nothing to offset their profitability because they’re not an operator or manufacturer. That’s why the financial institutions have historically been tax investors in housing, renewable energy, and other things that our government has wanted to promote.

The issue with that is there’s limited tax appetite. We’ve also lost many of our financial investors or banks in the last two years. But we want to take renewable energy from being alternative to mainstream. To do that, we need to change our regulatory and energy policy to open up the capital markets for traditional, 20-year utility loading. That’s my mission.

So what change needs to be made?
What we’d like to see is a national renewable portfolio standard that would require utilities to buy renewable energy. And that would help clear the price they pay for power. Then, that can be financed through bond markets or any of the capital that we have available in the United States. Actually, I think there’s adequate capital that’s interested in sustainable infrastructure development.

What role would the federal government play in the policy you favor?
Right now the government is providing an important bridge to get from a tax-oriented policy to a financial structure that’s less complicated. Tax investors helped grow the industry to where it is today — it wouldn’t be there without that. What was passed in the stimulus bill was a direct treasury grant to help continue renewable development as the capital markets recover [from the economic downturn]. Meanwhile, the government has worked on longer-term renewable energy portfolio standards and how we address carbon on a national basis. Because those are more complicated issues, they’re going to take more time.

In the interim, there’s a 30% direct cash grant refund that a project sponsor can apply for. We’re in the process of doing an application this week for two of our projects. That helps us continue to fund projects while the capital markets are recovering and fill some of the gap.

Turning to your role as a corporate CFO, what has it been like to start up a new department?
Not very many vacation days in the last three years. But as the first CFO for North America, I had the wonderful opportunity to build a finance organization from scratch. When I joined, our accounting system was outsourced. So I’ve developed the infrastructure for accounting, financial planning analysis, finance, asset management, compliance, and risk management.

How large a finance operation do you have?
I have a team at Acciona Energy North America; Acciona Wind Power has a team at our manufacturing plant; and also Acciona Solar Power has one. There’s an organization of about 30 and growing.

How do you balance your project finance role with the more traditional parts of a finance chief’s portfolio of tasks?

Because of the nature of the business, capital raising and having an external focus as a CFO is a critical part of my role and takes a good portion of my time. But I balance that with the operational side of the business. From the time we first go out and execute a land lease to the time we build and then close a project and then decide how we’re going to structure our financial statements and our reporting, it all has a finance-driven touch to it: to be able to go out and produce that package, to raise all those billions in capital. I’ve tried to make my finance organization function not only as a controllership; we have to be partners with all the cross-functional teams because they understand what the financial markets are like.

What role does the finance organization have in terms of compliance work for the assets in your portfolio?
Take our Red Hills wind project. I have two tax-equity investors and a lender. We have the monthly compliance of reporting to them. We do their tax returns and financial reporting. If we amend a contract, we have to make sure that what’s stated in the amendment is going to happen: it’s a 20-year living asset. We need to make sure we’re in compliance with that financial commitment we made to them as long as they’re continuing to do this.

Internally speaking, how is your company structured?
The closest business to what we do is a real estate company. But we invest in wind or solar companies, and they’re actually little limited liability companies. If you have a land lease, it’s not with Acciona Wind Energy, it’s with Red Hills. Each one of our projects is a little self-contained box that’s that particular asset. But even if we’re a portfolio company that raises the capital for a number of projects, we have a balance sheet and we raise corporate debt: that’s how we have to think about running and managing our business.

Do you tend to be an owner, a part-owner, or just an operator on these projects?
If it weren’t for the tax quirks in the U.S., Acciona would be what it typically is — a long-term owner-operator of wind projects. We try to bring in tax investors who monetize the project because they can get a majority of the tax attributes. Our financial structures let us become the majority long-term owner after the tax investors have gotten their investment, because they’re not long-term owners. So we run our projects like we’re the long-term owner. The investors also have the opportunity to flip down to a 5% ownership after they’ve gotten their return when the tax benefit runs off, in 7 to 10 years.

How many banking relationships do you have?
A lot. Globally, Acciona attracts banks that want to be relationship-oriented with an organization where they can have a long-term stable of lending activities. In the U.S., in addition to managing relationships with the project-finance arms of our global [financial] institutions, I’ve focused on bringing in new U.S.-based institutional investors to diversify and bring more capital to our activities: the life insurance companies, the John Hancocks, and the Prudentials.

Any pension funds?
We have not had any pension funds yet, but I’m talking to some because everyone’s heard that renewable energy now is sustainable. The financial crisis wasn’t caused by renewable energy; it’s actually been a very attractive and stable sector for investment. Pension funds need a long-term asset. They have a special interest, because some of them are labor oriented and may represent unions. And they’re saying, oh gee, renewable energy is creating jobs; if we invest in that sector, we’re a huge growth engine for new jobs.

What differences have you seen between the banks in Spain and the banks in the United States over the last year?
The Spanish lenders were not allowed by regulators to invest in mortgage paper. So fortunately the Spanish banks didn’t get into trouble. And they’re tremendous lenders to Acciona, so we benefited from having that continued stability with some of our core banks. European banks have generally restructured and gone through a reorganization with their governments.

They’re a very experienced and sophisticated lender group that has bought banks here in the U.S. When lenders are more conservative, there’s less capital and more deals chasing them. But as a CFO I have to make sure that our package rises to the top of their list.

The Spanish banks want to work with long-term sponsors, and particularly now they want projects that are well packaged, safe, stable investments. Having been on their side of the table, I also know that for bankers or institutional lenders like insurance companies, it’s important to have a package that they can literally cut and paste and go and get approved.

How do you feel about your job?
I have a dream job. To me, this is a perfect way to wrap everything I’ve learned in the last 20 years into working for a company where I can contribute to sustainability, renewable energy, and making the world a better place every day.

It is very, very satisfying that you can see a finished product that cross-functionally pulls the whole organization together. And we have an expression: we ring the bell. We ring the bell when we have a success like a financial closing or a power-purchase agreement. I hope to be ringing the bell a lot.
