Q&A: New report challenges assumption that bigger solar is better

In a time when hundreds of megawatts of large solar projects are underway in Minnesota, a new report suggests that smaller-scale solar projects could be just as good at delivering low-cost electricity.

John Farrell, director of the Institute for Local Self-Reliance’s Energy Democracy Initiative, argues in a recent paper that smaller-scale solar — and to a lesser degree wind — can be just as effective as utility-scale projects.

Why? Farrell’s research suggests that with transmission costs from remote wind and solar farms, having the source closer to users begins to make sense.

“Power that’s delivered at the distribution level might have a different value than generic wholesale power generation that comes on to the transmission system,” said Farrell, a nationally known solar expert.

Evidence in the paper — “Is Bigger Best in Renewable Energy?” — reveals that solar in particular is a bit more competitive at a smaller scale than wind. Economies of scale appear more favorable in the wind industry, where better and bigger equipment along with faster wind can offset higher transmission costs, he said. Still, the report doesn’t totally dismiss small wind, especially that which is community owned.

“Since sub­-5­-megawatt wind projects may be able to compete at a different price point, having community ownership may prove more economically lucrative (even with a slightly higher electricity price) than purchasing power from a remote wind farm,” Farrell wrote.

Part of Farrell’s argument is based on the Public Utility Regulatory Policies Act, or PURPA, which passed in 1978 to assist in renewable energy development. The act encourages utilities to buy power from independent producers if the price is less than what they would pay to generate the power.

The “avoided cost” became part of the equation for utilities in buying and developing power sources. By having power generators closer to users, the avoided costs make renewable energy more competitive.

That means the argument that bigger is always better in renewable energy isn’t always firmly rooted in economic reality, Farrell believes. The battle over distributed generation can be seen in the debate over rooftop solar where utilities are fighting against net metering for individual customers while at the same time building large solar projects.

He argues utilities like large-scale solar because they in many cases control and own it. Farrell has been studying the issue for several years and recently spoke with Midwest Energy News about his research.

Midwest Energy News: The argument for small wind, which you have advocated in the past, doesn’t seem to work as well as it does for solar. Why?

Farrell: The advantages of height and the bigger blades is dramatic in wind turbines, as is having a much bigger area to get wind energy. The advantage of small turbines is not quite as clear. You can’t really put a wind turbine of any size in an urban area. It has to be in a rural area and you don’t have as much electrical load to offset when you’re talking about building at a distributed scale.

Is there an approach to wind that might work?

Wind developer Dan Juhl has been exploring wind-solar hybrids, where there’s a couple of wind turbines that are utility scale and about 500 kilowatts to 1 megawatt (MW) of solar. He suggests installing them together near a utility substation to avoid that transmission cost. His argument and business model is that you can get a higher avoided cost under PURPA from the utility for that power because it has a good peak overlap with solar and avoids a lot of transmission costs. But it still requires utility-scale turbines.

What about solar panels that produce electricity?

Solar competes at any scale. It works at the residential, commercial and utility scale. The key finding in the report is that it’s not the size of the solar that determines whether it can compete, but it’s the price of the energy in the place it interconnects.

What are you seeing in the solar market?

There are two substantial economies of scale in solar, especially when you go from the kilowatt to megawatt scale. There’s a big diseconomy of scale at 100 MW. I’m not entirely sure what’s behind that. What I heard and read is that the interconnection and transmission costs for the largest solar projects are quite prohibitive relative to the distributed scale.

Is there an optimal size?

It’s under 20 MW, especially the 5 to 10 MW range, which turned out to be the lowest-cost scale. The 5 MW projects can use the fast-track interconnection process under FERC. They can interconnect at standardized and simplified rules and may be able to use existing capacity on the system without a build out.

How about the rooftop market?

Rooftop solar is really only competing with the retail electricity price or the value of solar, it isn’t really in competition with solar that delivers power at the wholesale level.  Think of it as the difference between room service and going to McDonald’s. The fact that one delivers to where you are makes it more valuable.

Is Minnesota going to see more rooftop solar?

We know that with the current level of incentives it is competitive because the market is growing. In the next five years, it is the level of incentives that determines whether rooftop solar is going to compete with retail electricity prices or the value of solar. Given the cost trajectory for solar and the inflation history of electricity prices, I have no doubt that rooftop solar will be competitive at the retail level in the next five years in Minnesota, without any local incentives and maybe even without the federal tax incentives.

We’re seeing much bigger solar farms than that in Minnesota and in other areas of the Midwest. Doesn’t that indicate big is good?

In 2015 Xcel Energy did a video called “Doing Solar Right” that argued solar should be at utility scale, not rooftops, because it’s cheaper. Xcel says that because they financially benefit from that, not because it’s necessarily true from a cost-benefit analysis. What I think is the most important takeaway here is to understand the motivation of the folks who are participating in this conversation about scale. Some people have something to benefit from bigger projects. There’s a lot of nuance and bigger is not always better.

U.S. conservative group backs Republicans who favor clean energy

U.S. conservative group backs Republicans who favor clean energy

By Valerie Volcovici

WASHINGTON (Reuters) - A conservative nonprofit group that lobbies Republicans to support clean energy policy will spend more than $1 million over the next few weeks to back 10 members of Congress running in the Nov. 8 elections, hoping to attract key swing voters such as millennials.

Citizens for Responsible Energy Solutions (CRES) is backing Republican House and Senate candidates who favor clean energy, even as Republican presidential nominee Donald Trump mocks wind energy and calls climate change a hoax.

Embracing a clean energy agenda can help Republicans win in close races by attracting key voters like millennials and women, and help broaden the Republican base, James Dozier, CRES executive director, told Reuters.

“The way I look at it is regardless of who is in the Oval Office, we need clean energy champions on the Hill," said Dozier, who added that Republicans have ceded the issue to Democrats.

“This is a ripe opportunity to reframe Republicans' engagement in energy debate,” said Dozier. “We see this as an issue the party can use to grow the tent with the next generation of voters, with female voters and Hispanics and African Americans.”

CRES kicked off its fall spending campaign last week with more than $200,000 in radio ad buys for Alaska Senator Lisa Murkowski and North Carolina Senator Richard Burr, who faces a close re-election race against challenger Deborah Ross.

The group will spend an additional $900,000 in support of other Republican candidates, including New Hampshire Senator Kelly Ayotte, who is neck-in-neck with Democratic Governor Maggie Hassan in her re-election bid, and Representative Joe Heck, who is running in the hotly contested race for the open Nevada Senate seat against Democrat Catherine Cortez Masto.

On the House side, CRES will spend money for ads and voter turnout efforts for representatives from Illinois, Virginia, Florida and New York.

CRES is not alone in backing Republicans who can help the party embrace clean energy policy and accept the science behind climate change.

Jay Faison, a North Carolina-based businessman, launched the $2 million Clear Path Action Fund to launch digital media campaigns for candidates, including Ayotte, who support clean energy in key swing states.

But these Republican efforts are dwarfed by spending from environmental PACs that are spending record amounts to back Democrats.

The League of Conservation Voters said it will spend a record $40 million this election cycle.

Other groups, including green activist billionaire Tom Steyer's NextGen and the Natural Resources Defense Council Action fund, have also announced tens of millions of dollars more in spending.

Corporations looking for 100% renewable energy including using PPAs

More than half of new wind capacity in 2015 was contracted through power purchase agreements, according to AWEA.

Utilities squeezed as corporations seek renewable energy elsewhere

As large corporations increasingly demand 100 percent renewable energy, many utilities are left in a bind: Add to their already excess capacity, or they can risk losing new customers to lower-priced third-party agreements.

“We have to figure out how to thread the needle with utilities,” said Letha Tawney who, as the director for utility innovation at the World Resources Institute, spends many of her waking and working hours trying to guide utilities into a new energy paradigm.

Many large power consumers have clearly demonstrated that, with or without their local utilities, they are moving towards a renewable future. That message was reiterated recently in Nevada when MGM Resorts International and Wynn Resorts paid a hefty upfront fee to Nevada Power to stop purchasing power from the utility and start buying it from other sources.

As of September, 62 of the country’s largest corporations had indicated their energy priorities by endorsing the Corporate Renewable Energy Buyers Principles. Other large institutions such as universities and military bases are moving in that direction as well.

Adam Kramer, the executive vice-president of strategy for Switch, a “transformational technology idea engine,” reflected on the company’s thinking in choosing Michigan for a new facility.

He said, “Our first question was: ‘Can you get us our power needs?’ The second question was: ‘Can you get us 100 percent renewable?’ If the answer was no, Michigan wasn’t going to be part of the site selection. From our perspective, energy is our lifeblood.”

States are eager to meet these companies’ demands, seeking the economic development prizes that follow.

“If we just think about large IT companies and the next big data center, access to 100 percent renewable energy for many of them is a requirement,” said Ryan Hodum, vice president of David Gardiner & Associates, a clean-energy adviser to businesses. “So a state that doesn’t provide that is at a competitive disadvantage.”

Power purchase agreements

In April, the American Wind Energy Association released a report with a telling finding: in 2015, for the first time ever, “major brands and other emerging non-utility customers signed 52 percent, or 2,074 megawatts, of the wind power capacity contracted through power-purchase agreements.”

“We have seen the number of corporate power-purchase agreements double year-on-year for five years straight,” Hodum said. “We expect that to continue – I don’t know if it will be at quite that pace. We think this is absolutely the type of mechanism that large companies are looking for, especially for some of these large off-site projects.”

That’s not to say that large power customers that want renewable power don’t wish to play ball with their local utility. According to Hodum, they do.

Rather, the escalating number of PPAs between large electricity customers and, in most cases, wind farms, suggests to Hodum that utilities aren’t acting fast enough. Large customers “have set these public commitments with targets for 2020, 2025,” he said. “There’s an urgency.”

At least 26 states – including Illinois, Iowa, Michigan and Ohio – allow electricity customers to obtain power from an entity other than their local utility through a power-purchase agreement. Some other states are attempting to join that list. A bill legalizing PPAs was introduced in the Missouri General Assembly each of the past two years. It got a bit more traction in 2016 than it did in 2015.

“There was corporate buy-in this year,” said P.J. Wilson, the executive director of Renew Missouri, a non-profit that supports legalizing power-purchase agreements. “These companies were saying, ‘We want and need access to renewable energy.’ ”

Another approach

Some utilities have responded to this demand with “green tariffs.” Utilities either purchase or invest in generating renewable energy, then offer it at a different – often higher – price to customers that want green energy.

“We’ve seen 10 utilities offer 11 different green-tariff products,” Tawney said. “Not all are successful yet, but they are all experiments. There’s a particularly interesting one: Rocky Mountain Power in Utah has put forward a product that would let a customer access a PPA while still a customer of Rocky Mountain Power.”

In 2012, the Utah legislature approved a mechanism that allows large customers to purchase renewable power from a third party, but to continue to pay Rocky Mountain Power for non-generation services such as transmission, distribution and billing.

The arrangement is available to customers with a demand of at least 5,000 kilowatts, according to a utility spokesman. It works well for them, he said, because their bills already are broken down to reflect the cost of each component of electrical service.

A few months ago, Dominion Virginia Power and an affiliate of Amazon crafted a system that allows the Amazon affiliate, Vadata, to sign power-purchase agreements with renewable generators while paying a price to Dominion that reflects the changing cost of power in the wholesale market.

These sorts of arrangements come with their own rate, or tariff, which typically has been higher than the utility’s going rate, according to Mark Lawlor, director of development at Clean Line Energy Partners.

Clean Line is trying to develop two long-distance transmission lines that would move wind energy from the Midwest toward the east. He would like to sell some of the wind power that would move across Missouri on the proposed Grain Belt Express to Ameren, one of the major utilities serving the state.

However, as he pointed out, it’s tough for utilities acting as intermediaries with their green tariffs to compete with power contracts made between power consumers and, in most cases, wind farms that are selling power at low prices.

“If I’m one of these companies, and you (the utility) want to charge me a premium for something that’s supposed to be cheaper, how do I get excited about that? Why should I pay a premium for something that’s supposed to be cheap?

“It seems to be this real challenge for utilities.”

In the short term, investment in renewable energy amounts to excess generation capacity for most utilities, Tawney conceded. However, she said, time will change the picture, especially in states that use a lot of coal, as do many Midwestern states.

“I think the states are realizing that simplifying cost-effective access to renewable energy is a more-and-more important economic driver” she said. “When more than 70 percent of Fortune 100 companies have set (sustainable energy) goals, it’s not an odd, one-off situation anymore. States that don’t do it will face economic-development headwinds. It’s too mainstream now.”
