John Petersen for Investor Intel: Rooftop solar is an odd duck. A consumer buys an expensive capital asset with the expectation that he’ll recover his investment through lower electric bills. As a matter of metaphysics, he’s decided to go into the power business with the primary goal of satisfying the most important and discriminating customer on the planet. The value proposition he currently offers his local electric utility is:
- I’ll buy less electricity from you because of my solar panels, but I need you on standby 24/7 to supply my nighttime needs and fill any weather related power production gaps;
- Since my solar panels will frequently produce more power than I need, I want you to give me credit for any excess power production, let me draw equivalent power from you when I need it, and structure it all as a tax free swap;
- You can, of course, bill me for any difference between what I deliver and what I take;
- I’ll have no duty to buy a fixed amount of power from you or deliver a fixed amount of power to you, but you must supply whatever I need and take whatever I don’t need; and
- You will be required to pay all of the costs associated with weather related production gaps and pass those costs through to your other customers.
Aclara Participates in White House Summit on 'Scaling Renewable Energy and Storage with Smart Markets;' Announces Commitment to Deploy 500,000 Smart Meters with Distributed Solar by 2025
Julia Pyper for GTM: A growing number of electric industry leaders agree that it’s only a matter of time before renewable energy resources dominate their grid systems.
In California, it’s already a reality, said Steve Berberich, president and CEO of California Independent System Operator Corporation. On a typical day, CAISO will pull about 30,000 megawatts of energy production, with around 6,500 megawatts from solar, 5,000 megawatts from wind and another 5,000 from geothermal and other services on the system. In addition, California’s grid system has roughly 4,000 megawatts of behind-the-meter solar, which is growing at a rate of about 70 megawatts per month.
In any given day, California gets more than 30 percent its electricity from renewable energy. On many days that amount climbs to 40 percent, and on some days renewables reach 50 percent, said Berberich.
“Now we have to think about the system as a renewable energy-based system complemented by other things,” he said, speaking at the Edison Electric Institute’s annual convention this week in Chicago. Cont'd...
Richard Martin for MIT Technology Review: Attempting to harness the power of distributed rooftop solar installations to make its grid more flexible and reliable, New York utility Consolidated Edison is launching a pilot program this summer to link dozens of small solar arrays into a single, software-connected power plant. The utility is working with solar power developer SunPower and energy storage company Sunverge to create a “virtual power plant”—a network of distributed assets that functions as a unified resource on the grid.
The project will include 300 homes with a combined total of 1.8 megawatts of solar capacity and batteries that can store up to four megawatt-hours of electricity, enough to run 300 average U.S. households for about 10 hours. Cont'd...

William Pentland, Contributor for Forbes: In Chile’s most recent power auction, the bids from solar project developers came in at between $65 and $68 per megawatt hour (MWh) were considerably more competitive than bids made by coal plants, which were priced at $85 per MWh. Solar power projects were awarded the lion’s share of the 1,200 gigawatt hours (GWh) of electricity contracts sold.
Chile boasts one of the world’s biggest solar resources. High electricity prices and strong demand from Chile’s mining industry have driven demand growth for solar, especially large scale commercial or utility projects.
The total installed solar capacity in Chile increased from less than 4 MW in 2013 to more than 220 MW last year. Nearly 1 GW of solar is projected to be installed in Chile in 2015. Meanwhile, a total of about 8 GW of solar power projects have been approved for development in Chile. First Solar and SunEdison are two of the biggest U.S. solar companies active in Chile. Cont'd...
Ken Silverstein for Forbes: The fall season is kicking off a sizzling solar power debate in California and one that has the potential to undercut the state’s climate mission.
Utility regulators there are in discussions over how to balance the interest of rooftop solar generators with the utilities on which they will still depend. Just how those hearings are resolved with have implications for the rollout of renewable energy not just in California but also around the country.
At issue is something called “net metering,” which is technical term used to measure the amount of money that rooftop solar generators should get paid relative to retail electricity prices. Utilities, generally, want to offer them the wholesale rate for what they send to them over the grid. Those are expensive wires to maintain and ones that all customers will use, even those who power their homes with solar panels. That’s because the sun is not always shining and the utilities would then have to provide them electricity over their networks.
The present net metering rules in California were set a dozen years ago, with the intent that they would expire when solar penetration reached 5 percent at any of three investor-owned utilities: Edison International’s SoCalEd, PG&E Corp. and Sempra Energy, which is nearing the threshold. Generally, those utilities are paying customers the full retail value for their electricity generated and transmitted. Cont'd...
