Under recently approved market changes, the California Independent System Operator seeks to double down to protect reliability in the states of the Western Interconnection it serves while guarding the transition to growing levels of variable and distributed renewables. The Federal Energy Regulatory Commission approved CAISO’s interim market mechanisms in late June to allow more efficient […]

Updated Feb. 18 In a reversal of high heat and demand causing rolling blackouts in California, Texas suffered far larger and longer blackouts this week because of unusually icy conditions. More than 4 million customers lost power because thermal power plants were unable to operate. Wind turbines also froze. “Extreme weather conditions caused many generating […]

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 […]

California’s energy imbalance market had a good 2020. It passed $1 billion in total benefits, added two powerhouse participants, and filed its first plan for expanding into day-ahead trading. But the question of how California can share decision-making with other states continues to block that expansion and potential participants are looking at alternatives. The voluntary EIM […]

The new chief of the California Independent System Operator, Elliot Mainzer, announced an executive reorganization Nov. 6. It switches around managers in market policy, operations, planning and technology departments with the aim of broadening their understanding of how the grid works as it moves towards decarbonization.  “Internal mobility brings new thinking, new blood and new […]

The California Independent System Operator saw a whopping 17% reduction in overall wholesale electricity market costs in 2019 compared to the year before, thanks to energy efficiency, the deployment of small renewables, more hydropower and less natural gas. Total energy costs last year were $8.8 billion, at an average $41 per megawatt-hour, compared to $10.8 […]

Landowners’ legal challenge to the Federal Energy Regulatory Commission’s practice of allowing land to be seized for a pipeline before deciding whether to reconsider a granted permit forces FERC to ease its rehearing rules. However, the one dissenting commissioner says the new rule is a hollow victory for aggrieved property owners. Private and public utilities […]

Falling sun and wind resources occurring as demand rises, particularly in the evenings, has created a worsening supply gap. It grew 50% this year, California Independent System Operator Chief Executive Officer and President Steve Berberich said. This gap or ramp is now 15,000 MW over a three-hour stretch.  It is expected to reach 20,000 MW. […]

The California Public Utilities Commission says goodbye to President Mike Picker. The five commissioners also approve new decade-long energy efficiency targets and SDG&E’s $100 million heavy-duty vehicle electrification program. The California Independent System Operator gets a CEC pat on the back for being the new Reliability Coordinator. The Energy Commission also adopts impressive new rules […]

The announcement by California’s transmission operator that it will become the regional coordinator, not only in its territory, but across big parts of the western grid beginning July 1 generated few headlines. However, the California Independent System Operator becoming the new high wires reliability cop on the beat from Northern Mexico to Canada is a […]

Q & A with Lorenzo Kristov The California Independent System Operator’s former principal of market design and infrastructure policy PART 1 Editor’s Note: In a recent editorial in the San Francisco Chronicle, Lorenzo Kristov and Mark Ferron, former CAISO board member, advocated for an “open access” distribution system and indicated that local planning increasingly is “where […]

The grid operator’s chief executive officer went off script in his report to board this week to lambaste those who opposed AB 813. The bill would have authorized the California Independent System Operator to create a multi-state grid and wholesale power market in the West. “Those who opposed this are on the wrong side of […]

A legislative hearing on tracking carbon from electrons delivered to Californians quickly turned into a debate about grid regionalization and the impact of community choice aggregators and direct access providers in the state Capitol on July 2. Liane Randolph, California Public Utilities Commission member, said her agency has targeted a reduction of 42 million tons […]

As community choice aggregation, distributed generation, and interest by companies in making or purchasing their own power rise, California energy officials appear ready to change the state’s electricity market under the banner of “customer choice.” It’s uncertain what the California Public Utilities Commission will recommend in its final analysis outlining how customer choice is changing […]

Suddenly, all eyes are turned toward the likely prospect California lawmakers will soon enable a regionalized western power grid and wholesale market. Regionalization was on the table a few years ago, but progress largely faltered on concerns it would enable more coal power to flow into California, confounding the state’s march to decarbonize its economy. […]

Grid regionalization legislation appears to be back on the table, with draft language being circulated in Sacramento by Assembly Utilities & Energy Committee Chair Chris Holden (D-Pasadena). Holden amended a bill late in last year’s legislative session to include provisions to allow the California Independent System Operator to move forward with a regionalized western grid […]

The California grid operator plans to begin providing reliability coordination services in its territory and potentially to other interested balancing authorities in the western U.S. beginning in late 2019. The California Independent System Operator announced its plan Jan. 2 in response to the expected departure of Mountain West Transmission Group from Peak Reliability and the […]

Greening the grid is the talk of the town. At the CAISO’s annual confab held this week, most bets are that a westward grid expansion will happen. Why? Because proponents insist it will promote renewables, which will decarbonize both the grid and economy, near and far. Achieving that goal, however, requires paying new alternative resources […]

A top legislative staffer gives an insider’s look at the fallout from the governor’s ill-fated effort to push through a bill to create an integrated western grid in the waning days of the legislative session. Electric transportation advocates flock to a meeting this week on the California Air Resources Board’s plan to give away $1.5 […]

The most significant state energy bills of the year stopped breathing the final week of this legislative session. Legislation to set a 100 percent carbon free-power mandate for California by 2045, with the last 40 percent from large hydro, failed to come up for a vote before the wee hours of Sept. 16, the session’s […]
