Grid Operator Raises Its Extreme Summer Peak Estimate by 6%

13 May

The California Independent System Operator is “cautiously optimistic” that the grid will be more stable this summer than last because there will be 2,000 MW of added resources by Sept. 1 to help meet soaring consumption from cranked up air conditioners as the sun sets in late afternoon and early evening. That includes supply from […]

CEC Okays Big Green Energy Grants, More Diesel Backup Looms

14 Apr

The California Energy Commission approved $73 million in grants for clean energy projects, ranging from advanced communications within batteries for fast electric vehicle charging, flexible demand response, to green microgrids. The five commissioners also moved closer April 14 to voting on two more big diesel backup generator projects at data centers. The decisive vote on […]

CPUC Summer Demand Side Decision Cuts Back on Fossil Power

25 Mar

The California Public Utilities Commission March 25 unanimously approved a revised emergency resource plan for the private utilities for the next two summers. Unlike the initial proposal, this new decision prohibits using increased gas generation from plants with existing contracts and from revived plants to meet high demand. Many clean air advocates were pleased by […]

Bills to Promote Green Hydrogen and Large Customer Demand Response Advance

16 Mar

A handful of measures passed out of the key Senate Energy, Utilities & Communications Committee March 15. One expands the definition of green hydrogen; one adds statutory protections to a demand response program that pays commercial and industrial customers to shed load, and the third seeks to increase poor communities’ access to distributed resources. SB […]

Roundup: East Bay to Offset Peak Load w/ Negawatts Reaped Elsewhere

4 Mar

East Bay Community Energy signed a deal with home energy management company OhmConnect to apply 25 MW in aggregated energy reductions to EBCE’s peak load during evening hours as solar power diminishes. It’s a novel demand response arrangement. The transaction does not sign up EBCE customer into the ‘negawatt’ program but instead taps into the […]

4 Feb

State regulatory staff propose further crimping demand response, much to the dismay of advocates of these behind-the-meter resources. Making matters worse for them is the disparity in treatment between DR and fossil power plants. The City of San Diego plans to issue a second request for bids for electricity and gas services because the long-time […]

CPUC is Heading Backwards on Demand Response Forward on Gas Plants

4 Feb

Instead of increasing demand response to help avoid blackouts during intense heat, a California Public Utilities Commission staff proposal would continue restricting its use on grounds some resources failed to show up during the August outages. At the same time, the fleet of gas plants are getting increased financial support in order to play a […]

Final Blackout Study Calls for More Reserves, Warns of Diablo & Pacific Line Risk

14 Jan

Details on the key causes of the mid-August blackouts are out, and consistent with an earlier analysis. They highlight market and planning flaws and a system thin on the cushion of extra power, or resource adequacy, the grid requires. The final analysis also points to an acute concern over two scenarios: a sudden loss of […]

Edison Reimagines California’s Distribution System

5 Jan

Distributed energy’s explosive growth makes integrating it in a way that supports the power system critical, according to a new white paper from Southern California Edison. The paper forecasts significant growth of distributed energy resources (DER) in California and “we want to have the system technologies to see and manage their impacts,” SCE VP of Asset […]

Liane Randolph, who has been at the California Public Utilities Commission for the last five years is making a big move. She is the next Air Resources Board chair, replacing Mary Nichols, who may head to Washington DC. Southern California Edison signs another big round of energy storage deals this week. That includes 585 MW […]

JUICE: CAISO Board’s First Woman Chair Focuses on Renewable Integration

9 Dec

The California Independent System Operator is charged with operating 80% of the state’s massive electric highway. The first board of this semi-public entity launched in May 1997. It had 25 directors, five of them women. It included a range of representatives, from private utilities, to independent generation companies, which thrived temporarily, to environmentalists. The first […]

Integrating Variable Resources and Flexible Demand

7 Dec

What is the best way to mix in growing levels of intermittent renewable resources in networks such as California’s, as it marches towards a 100% clean energy portfolio by 2045? Among the usual suspects are better interconnections, and more generation diversity, including more storage and price responsive demand, a resource traditionally neglected. A newly released […]

19 Nov

State utility regulators aim to move on demand side resources to avoid outages when it is roasting hot next summer. They plan to take the unusual step of expediting changes to California Public Utilities Commission resource adequacy, demand response and other load reduction programs. Over at the nation’s capital, the Federal Energy Regulatory Commission holds […]

CPUC Will Scour for Demand Side Resources

19 Nov

In order to avoid a replay of rolling blackouts next summer, the California Public Utilities Commission voted unanimously to expedite rules to get more resources connected to the grid, avoiding the typical, years-long process. The new rulemaking considers temporary changes to resource adequacy, demand response, load shifting and other like programs and rules.  The commission […]

New Energy Providers Join Forces Against Entrenched Agency Rules

29 Oct

Bureaucratic red tape at the California Public Utilities Commission prevented East Bay Community Energy from contracting for clean, behind-the-meter electricity last year that could have provided power or lowered demand during the August heat waves. The resources were designated to help meet East Bay’s 2020 resource adequacy obligations. The community aggregator says it also is […]

Lawmakers Told Grid Imbalances Can Be Solved by Next Summer

13 Oct

The California Assembly Utilities & Energy Committee Vice Chair Jim Patterson (R-Fresno) castigated the state’s three energy agencies at a Monday hearing, saying their joint report on rolling outages in August was essentially finger pointing and excuses. The heads of those agencies, the California Public Utilities Commission, grid operator and California Energy Commission, continued to […]

Groundbreaking action by federal regulators requires grid operators to open their doors to aggregated power from energy storage, solar rooftops, electric vehicles, and energy efficiency. CAISO is ahead of the regional transmission operator pack, but the new rule is expected to ease the way for more clean distributed resources into its grid. The Federal Energy […]

Juice: Scrutiny of Demand Response Failures Needed

15 Sep

The analysis of the rolling blackouts is in the works but there was advanced warning of some serious systematic problems, making some mistakes avoidable. The joint agency root cause report of the mid-August blackouts may be underway, but some problems were just waiting to happen. California was clearly and inexcusably on a path to rely […]

The Cause of California’s Blackouts

8 Sep

Under Gov. Gavin Newsom’s order, the California Public Utilities Commission has initiated a “root-cause analysis” of the state’s August 14-15 blackouts. Its joint report with the grid operator and California Energy Commission is expected to be completed at the end of this month. The blackouts were “intolerable,” but combined with the pandemic, west-wide heat storm, […]

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 […]
