California regulators first to allow multiple revenue streams for energy storage. Also, Maryland Storage Tax Credit pays 30%

Feb. 13, 2018, Utility Dive The state has approved rules that increase the ways for energy storage systems to make money, for example, through frequency regulation, capacity or spinning reserve services.  The California Public Utilities Commission in mid-January became the first state regulator to issue revenue stacking rules for energy storage projects, but the rules could be more of a starting point …

Solar and batteries are edging out gas, and batteries are becoming bigger for Tesla too

Bloomberg, Feb 2018 Natural gas is getting edged out of power markets across the U.S. by two energy sources that, together, are proving to be an unbeatable mix: solar and batteries. In just the latest example, First Solar Inc. won a power contract to supply Arizona’s biggest utility when electricity demand on its system typically peaks, between 3 p.m. and 8 p.m. The panel …

Many ways to avoid blackouts and save money in the shift to 100% renewable, reliable energy, worldwide

Researchers propose three separate ways to avoid blackouts if the world transitions all its energy to electricity or direct heat and provides the energy with 100 percent wind, water and sunlight. The solutions reduce energy requirements, health damage and climate damage. Key elements of the solution applicable to different cases are to Produce heat directly from solar and geothermal heat …

Rooftop Solar + Storage = Hurricane Energy Resiliency. Roof-mounted systems and nearly all ground-mounted systems in Florida came through Hurricane Irma

Clean Technica, Feb 2018, by Danny Parker Figure 1: Hurricane Irma Bears Down on Florida on September 8th, 2017. (NOAA) Improving Storm Resiliency with Rooftop Solar & Electrical Storage One series of complaints in the wake of Hurricane Irma came from some individuals who had installed solar electric PV systems and then were unable to use the produced solar power …

California requires state’s biggest utility to rely on batteries for demand peaks

From Bloomberg: A New Era of Batteries Spells Trouble for Gas in America, By  Mark Chediak January 11, 2018 California, the state that helped birth the global boom in battery-toting electric vehicles, is trying to spark a similar transformation for utilities. And that spells trouble for power plants all across the U.S. that run on natural gas. The California Public Utilities Commission approved an order Thursday that …

Renewable energy bids in Colorado for Xcel Energy

Citizens’ input/Letter to Editor of Denver Post: Renewable Electricity Now: Good for the Environment, Good for the Ratepayers It is now clear that the costs of wind, solar and battery storage have recently dropped dramatically, and adding large amounts of these clean technologies to our electric grid can reduce costs to ratepayers.1  Yet Xcel Energy has declined to perform a …

Battery breakthroughs

December 21st, 2017 by Steve Hanley  on Clean Technica Batteries are the key to the zero carbon future, there’s little argument about that. But today’s batteries are less than ideal in many respects. They cost too much, are too big, weigh too much, function poorly in low temperatures, are prone to catch fire under certain circumstances, or simply don’t last long enough. …

The Death Of Oil: Scientists Eyeball 2X EV Battery Range

By Tina Casey on Clean Technica, 19 Dec 2017  For someone who’s all in for fossil fuels, President* Trump sure has a thing for electric vehicles. Last October the US Energy Department announced $15 million in funding to jumpstart the next generation of “extremely” fast charging systems, and last week the agency’s SLAC National Accelerator Laboratory announced a breakthrough discovery for doubling …

Siemens Gamesa expects to deliver stored energy at a cost of less than €0.10 ($0.12) per kilowatt-hour with hot rock storage technology

By Jason Deign, GTM, 18 Dec 2017 – Siemens Gamesa Starts Building Hot Rock Plant for Long-Duration Grid Storage: The Future Energy Solution project in Hamburg will use surplus power to heat rocks to 600 degrees Celsius. An artistic approximation of the experimental technology that will store surplus energy by heating up 1,000 tons of rock. Photo Credit: Peter Hindmarsh / …
