Matching Flexible Demand with Green Load

2 Dec

What is the best way to integrate growing levels of variable renewable resources into grid networks such as in California, as it marches towards 100% renewable mix by 2045? Among the usual suspects are better interconnections, and more generation diversity, including more storage and price responsive demand, a resource traditionally neglected. This subject is gaining […]

Guest Juice: Solar Gets Better, Cheaper

24 Nov

By Feiridoon Sioshansi Solar projects, particularly the utility-scale variety, are now considered the cheapest way to generate power in California and many other parts of the U.S., according to the Lawrence Berkeley National Laboratory’s new report 2020 Utility-Scale Solar Data Update. It provides the latest trends in ground-mounted solar projects larger than 5 MWAC. It […]

CAISO Rules Evolve to Accommodate Solar Plus Storage

19 Nov

To accommodate the growth in battery projects paired with solar plants, the California grid operator’s board Nov. 18 further loosened constraints and will allow project operators to send more or less power into the market than initially bid. Allowing deviations from original bids aims to use more renewable power produced by combined solar-battery generators, reducing […]

State Regulators Face Solar Dilemma

3 Nov

Monday’s kickoff of California’s long-awaited proceeding to update net energy metering highlighted regulators’ dilemma of how to grow solar resources without shifting system costs to customers who don’t own solar energy projects.

Major stakeholders—from utilities to community energy—insist that clean reliable resources are needed now more than ever. The California Public […]

Report: Salton Sea ‘Lithium Valley’ Could Supply 33% of Global Demand

6 Oct

Just one week after a law was signed in California creating a special committee to explore the potential of the Salton Sea to yield significant amounts of lithium, a report concludes it could result in a multi-billion dollar windfall for the state and its electric vehicles. The report by the non-profit New Energy Nexus says […]

California is Driving the Hydrogen Fuel Market

6 Oct

California has been a leader in hydrogen-fueled transportation and today is home to nearly all the hydrogen fuel cell electric vehicles in the United States. There are about 7,000 of these vehicles on state roads, and only another 600 spread across the whole country. Seven thousand vehicles is very few, but hydrogen vehicles are likely […]

Withered Demand Response Blamed for Rolling Outages

26 Aug

The grid operator, state energy regulators and utilities largely abandoned demand response that would have provided enough electricity to avert outages during the recent heat wave, advocates of the policy say. And the numbers back them up. Rather than strengthen demand response, in which energy users cut back to leave more electricity on the grid […]

Rising Concern Over Diesel Generators

25 Aug

Pacific Gas & Electric came under fire for relying on diesel generators at a special joint energy and air agency day-long meeting Aug. 25. The utility is now moving large generators into 62 substations to provide backup power to communities in the event of outages provoked by fire. But generators owned by PG&E and others […]

Officials Demand PG&E Limit Shutoffs, Protect the Vulnerable
