A grid with a million solar rooftops

Bill McKibben wrote for Rolling Stone 11 April 2013, The Fossil Fuel Resistance,

A grid with a million solar rooftops feels more like the Internet than ConEd; it’s a farmers market in electrons, with the local control that it implies.

Distributed solar power is exactly what electric utilities fear. There’s a reason why Southern Company CEO Thomas A. Fanning consistently ranks “renewables” as his second-to-last power source; the only thing worse for big baseload utilities is his last one: efficiency, which could remove all demand for additional electrical supply in Georgia.

How big of an opportunity for the rest of us is this threat to the cozy business model of big baseload utilities? Continue reading →

IKEA biggest solar in Georgia

The biggest solar rooftop installation in Georgia? Not by mighty Georgia Power, not by an EMC, not even by GaSU: it’s IKEA’s distribution center in Chatham County. Chatham is also trailing only Atlanta in solar installations in general.

Mary Landers wrote for Savannahnow.com 7 January 2013, New solar adds to Chatham’s growing inventory,

Just in time for the new year, and for a tax break for the old one, Consolidated Utilities began producing electricity from solar panels at its water treatment plant in west Chatham County on the afternoon of New Year’s Eve.

“When I left on Monday the meter was receiving power,” said Tony Abbott, president of Consolidated Utilities, a private local water company.

The 416-panel, 100-kilowatt system is big enough to power about 10 average homes for 25 years, said Julian Smith, of SolarSmith, which installed the system. At the water treatment site, however, solar will instead power the blowers that keep the sewage ponds aerated. The panels occupy previously useless property in a flood zone, Smith noted.

OK, the Wiregrass Solar installation at Valdosta’s Mud Creek Wastewater Treatment Plant is larger, and the Valdosta City Council recently voted to expand it further. Go Valdosta!

But what about IKEA?

It’s not the largest solar installation in the county. That honor still goes to the IKEA distribution center, which in October plugged in its 1,460-kilowatt solar array on the roof of its distribution center. That IKEA installation is in fact the largest in the state.

Back in July I mentioned that IKEA was going to build that array, and IKEA was building almost as much solar as all of Georgia Power’s parent Southern Company. BusinessWire reported 9 Oct 2012 IKEA Plugs-In Georgia’s Largest Private Solar Rooftop Array on Savannah Distribution Center: Surpasses 75% U.S. Solar Presence.

This installation represents the 34th completed solar project for IKEA in the U.S., with five more locations underway, making the eventual U.S. solar presence of IKEA nearly 89% of its U.S. locations, generating with a total 38 MW. IKEA owns and operates each of its solar PV energy systems atop its buildings — as opposed to a solar lease or PPA (power purchase agreement) — and globally has allocated €590 million to invest in renewable energy, focusing on solar and wind during the coming three years. This investment reinforces the long-term commitment of IKEA to sustainability and confidence in photovoltaic (PV) technology. More than 250,000 solar panels have been installed on IKEA stores and buildings across the world. The company also owns and/or operates approximately 110 wind turbines in Europe.

The Savannahnow article mentions something happening in Chatham County but not so much yet in Lowndes County:

“What’s really going on in Chatham is that lots of homeowners put solar on their rooftops,” Arora said. “The excitement exists in Chatham for solar.”

Renewable energy much needed in Georgia —John S. Quarterman

My op-ed in the VDT today; I’ve added links, plus some more after the op-ed.

Finally! Kewaunee, Calvert Cliffs, and now Crystal River permanently closing say it’s time for Georgia to stop wasting money on Southern Company’s already over-budget and increasingly-late nukes and get on with solar power and wind off the coast: for jobs, for energy independence, and for clean air and plenty of clean water.

February 2013:
Duke Energy is closing the Crystal River nuclear reactor (Tampa Bay Times, 6 Feb 2013), 160 miles south of us, because nobody wants to pay to fix it: between “$1.5 billion and $3.4 billion, plus what it costs to buy power to replace what Crystal River would have produced while it is being repaired” [Charlotte Business Journal, 11 Jan 2013].
November 2012:
NRC terminated Maryland’s Calvert Cliffs 3 (NRC 1 Nov 2012) after Constellation Energy dropped out because the cost “is too high and creates too much risk for Constellation” [Bloomberg 10 Oct 2010].

Rooftop solar: the most direct route to clean energy industries

Austin vs. San Antonio in solar power Around here I hear local leaders say “we’ll never be Austin.” Well, Austin may be letting San Antonio pass Austin as far as rooftop solar and the jobs that generates. It’s not a matter of size or pre-existing advantages. It’s a matter of political will. Do we have that will here?

TexasVox wrote a white paper in February 2012, Solar Austin: Rooftop Solar & Job Creation,

…the most direct route to attracting and encouraging the development of clean energy industries is through the

the scale of future development will be orders of magnitude greater than what has occurred to date.
mass deployment of local rooftop solar, which is probably why solar has by far the most significant presence of any clean energy generation technology in Austin.

But the paper’s point is that Austin is falling short. Look at the graph: Austin seems to have settled for linear growth in solar power, while San Antonio gets it about compound growth. As San Antonio Mayor Julian Castro said in 2011, solar power is in

Industrial Authority working for solar in south Georgia @ VLCIA 2012-12-18

The Industrial Authority is working to find locations for some of the 210 MW Georgia Power got the PSC to shift from biomass to solar back in September. That’s a good next step.

Jason Schaefer wrote for the VDT 23 Dec 2012, Solar power push has Authority working to establish connections,

Since the Georgia Public Service Commission (PSC) approved Georgia Allan Ricketts, Projects and Existing Industry Manager, VLCIA, 2012-12-18 Power Company’s plan Nov. 20 to add 210 megawatts of solar power to its electrical grid, the Valdosta-Lowndes County Industrial Authority has been devising strategies to draw solar energy producers to South Georgia.

Georgia Power will issue a Request for Proposals (RFP) from solar energy collection and production companies in early 2013, according to the PSC, and the company will contract with the lowest bidders to purchase their energy and place it on the Georgia Power electrical grid for public consumption.

Georgia Power plans to add 90 megawatts to its grid from distributed generation (small companies producing between 100 kilowatts and 1 megawatt), and 120 megawatts of large utility-scale projects producing up to 20 megawatts each. The company plans to price the solar energy at $0.13 per kWh for distributed generation and up to $0.12 per kWh for utility-scale projects, according to the PSC.

This government-approved commercial push for solar energy could be a boon to sunny South Georgia as well as the greater Valdosta area specifically, and the Authority is prepared to accommodate the solar energy producers they expect.

Andrew Schruijer, Executive Director, VLCIA, 2012-12-18 “I think there’s a very good possibility of solar energy coming to South Georgia,” Executive Director Andrea Schruijer said. “Possibly in the near future.”

There’s more in the VDT story. It’s pretty much what Col. Ricketts also told me after the VLCIA meeting Tuesday a week ago. He asked me if I knew what “distributed” meant. I pointed out Georgia Power’s version of distributed was actually not very distributed, compared to Continue reading →

U.S. has plenty of solar energy everywhere —Jennifer DeCesaro of DoE

Jennifer DeCesaro of the U.S. Department of Energy (DoE) said she liked showing a map of U.S. insolation outside the U.S. southwest because then she could point out that Spain has not as good resources and a larger solar market, while Germany, the world leader in deployed solar, has solar resources like the state of Alaska. So the U.S. has plenty of solar energy everywhere.

She made a few other comparisons between U.S. and Germany. U.S.: 30% investment tax credit. Germany: National Feed-in Tariff.

She talked about SunShot: the Apollo mission of our time. It aims to reduce solar costs by 75% by the end of the decade, making solar cost-competitive with fossil fuels without subsidy.

Actual panels cost about the same in U.S. and Germany, but the rest Continue reading →
