Australians Put About 1 GW of Solar on Their Roofs Last Year

Australian homeowners and businesses installed 1.1 GW of solar PV last year, mostly for rooftop solar, according to the Australian Clean Energy Regulator’s (CER) Small-Scale Renewable Energy Scheme data released yesterday. CER said that Australians preferred larger capacity systems in 2017 to reduce costs. The average solar system capacity doubled since 2012, from 3 kW to 6 kW.

Power-to-Gas in Microgrids: Competitive with Batteries?

Power-to-gas, a technology that converts excess renewable energy to gases that can be stored, is cost-competitive with lithium-ion batteries in microgrids, according to Matt Gregori, technology development manager, Southern California Gas. Gregori spoke at a solar conference last week at the University of California, Riverside.

What Is Driving Cooperatives to Deploy Energy Storage?

The use of batteries to reduce peak demand charges may be one of the most clearly defined business cases for battery energy storage among electric distribution cooperatives in the U.S., according to a report released yesterday by cooperative bank CoBank’s Knowledge Exchange Division.

Tackling the perverse incentive: Utilities need new cost recovery mechanisms for new technologies

The perverse incentive built into the way regulated utilities recover costs and earn profits is becoming an obstacle to utilities providing the best service to their customers. The perverse incentive rewards utilities with a profit margin for making capital investments, but not for contracted services that might serve customers better. It has become an increasing concern as utilities discover that contracted services for distributed energy resources (DER) and cloud computing may provide more reliable and affordable customer service in certain circumstances.

Utilities are paying their customers to buy electric vehicles

Electricity utilities were never designed for a world in which electricity demand didn’t go up forever. For a century, that was fine. But after 2005, US demand leveled off and, in some regions, began to decline. The Tennessee Valley Authority is now preparing for an unprecedented 13% drop in demand across the region it serves in seven states, Vox reports, the first sustained drop in the utility’s 85-year history.
