Solar is now competitive with … natural gas –Crossborder Energy study

Colorado, California, North Carolina: when will Georgia catch up in solar power? What will it take to get the Georgia legislature to realize all Georgians will benefit economically from much more solar power than GA PSC in July required Georgia Power to buy? And why should we permit a methane gas pipeline to gash through Georgia to profit executives in Houston and Juno Beach, Florida when we could be deploying solar everywhere in Georgia for local jobs, profit, lower electric bills, and clean air and water?

Here’s the study that showed solar benefits outweigh costs in North Carolina, The Benefits and Costs of Solar Generation for Electric Ratepayers in North Carolina, by R. Thomas Beach and Patrick G. McGuire for Crossborder Energy, 18 October 2013.

Wholesale solar PPA prices provide perhaps the most dramatic evidence of the continued decline in solar PV costs. Solar PPA prices have fallen dramatically over the past several years, to the point that, in some regions of the U.S., solar is now competitive with other generation resources, including wind and natural gas. Xcel Energy in Colorado recently announced that it is proposing to add 170 MW of utility-scale solar to its system, with its CEO stating “[f]or the first time ever, we are adding cost competitive utility scale solar to the system.”33 The California electric utilities make public each year the average PPA prices for renewable contracts approved by the CPUC in the prior year. Figure 3 shows the trend in the prices for their solar PV PPAs; CPUC contract approval can occur up to a year or more after bids are received, so the figure is indicative of prices through roughly 2011.34 2012 solicitations for solar PPAs in California in the 3 MW to 20 MW size range through the Renewable Auction Mechanism (RAM) have yielded market-clearing prices in the 8 to 9 cents per kWh range.3

The Lawrence Berkeley National Lab (LBNL) conducts and publishes regular national surveys of the installed costs of solar PV; these surveys include Continue reading →

57% of Colorado electricity from wind on 15 April 2012

Steve Hargreaves wrote for CNN Money 6 August 2012, Wind power hits 57% mark in Colorado

During the early morning hours of April 15, with a steady breeze blowing down Colorado's Front Range, the state's biggest utility set a U.S. record — nearly 57% of the electricity being generated was coming from wind power.

As dawn came and the 1.4 million customers in Xcel Energy's service district began turning on the lights, toasters and other appliances, the utility's coal and natural gas-fired power plants ramped up production and brought wind's contribution back closer to its 2012 average of 17%.

The article also included the usual power company quibble:

"A lot of utilities don't want to contract large amounts of wind because it's volatile," said Amy Grace, a wind analyst at Bloomberg New Energy Finance. "Anything over 25%, and utilities get nervous."

They neglected to mention that the traditional rigid grid connecting big baseload power plants failed for millions of Americans in June and failed for 600 million Indians in July. More renewable energy distributed through a smart grid would help prevent that.

In any case, 17% is a significant percentage to start with.

WSJ on Economic Problems of Biomass Plants

Jim Carlton points out in the Wall Street Journal some of the problems of biomass plants.
With all the plants and trees in the world, biomass energy would appear to have boundless potential.
Or as Georgia politicians are fond of saying, “Georgia is the Saudi Arabia of forest energy.”
Yet in the U.S., biomass power—generated mainly by burning wood and other plant debris—has run into roadblocks that have stymied its growth.

Here at the Northern Nevada Correctional Center, officials in 2007 built a $7.7 million biomass plant to meet all the power needs of the medium-security prison. But last month, two years after the plant opened, prison officials closed it, citing excessive costs.

“This was a project that was well intentioned, but not well implemented,” says Jeff Mohlenkamp, deputy director of support services for the Nevada Department of Corrections.

Even with a captive market (pun intended), biomass was not economically feasible.

Maybe it was an isolated case? Continue reading →

Solar Companies Booming in Buffalo

There’s still time to lead the solar parade:
“The solar market is the fastest-growing market worldwide, bar none,” said Ryne P. Raffaelle, director of the U.S. Department of Energy’s National Center for Photovoltaics in Colorado. “For the last half-dozen years, it’s grown at about a 40 to 45 percent compound annual growth rate per year.”

That growth is expected to accelerate next year, said Raffaelle, who was a Rochester Institute of Technology faculty member for 10 years. But the vast majority of that growth, both in the manufacturing and deployment of systems, is happening outside the United States. Asia has taken a “commanding lead” in manufacturing, and Europe leads in deployment, he said.

“But the rest of the world, they’re still watching the United States. They still see us as the 800-pound gorilla,” Raffaelle said. “It’s like, ‘When are they going to do something?'”

That was from a conference held in the Buffalo area recently.

In Buffalo, New York, they’re not just talking about solar power: Continue reading →
