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 […]

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. […]

Earlier this year, state and federal energy officials were ringing their hands that the summer would bring natural gas and electricity shortages and price spikes in Southern California. The assumed culprit was continued limits on SoCal Gas Aliso Canyon natural gas storage field operations and several pipeline outages in the utility’s system. So far the […]

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 […]

The grid operator’s newly approved budget for the coming year sets a revenue requirement of $193.5 million. It is 2 percent lower than the adopted requirement for 2018.

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 […]

The East Bay’s new community choice program adopts a five-year local investment plan that targets local renewable energy, energy efficiency, and electric transportation. In an increasingly rare display of bipartisanship in Washington, members of both parties in the House praise the growing role of energy storage technology during a committee hearing this week. Current’s Juice […]

As the deadline for voting on legislation to allow California’s grid to become a regional entity gets closer, debate rages on as to whether it would be a boom or bust. A report released July 17, favoring removing barriers to establishing a Western Independent System Operator, warns of the inherent complexities of the legislation, AB […]

Pacific Gas & Electric notifies investors and lenders that it is taking a $2.5 billion loss in the second quarter as a result of mounting wildfire liability, with the worst potentially yet ahead. Meanwhile, a legislative committee in Sacramento advances a bill that may ease utility liability for wildfires. The California Public Utilities Commission sets […]

The Bonneville Power Administration is keeping an eye on how flows of electricity to California and others in the grid operator’s Energy Imbalance Market might affect its ability to provide reliable power to the Pacific Northwest. Russell Mantifel, Bonneville EIM access program manager, outlined the effort in a presentation Nov. 28 at the Regional EIM […]

If California becomes part of a western grid, is the vehicle important? Specifically, is it better for the California Independent System Operator to formally grow or for western states to join an expanded Southwest Power Pool? While nobody expects the Southwest Power Pool to ever reach California, there’s growing concern about the pool expanding into […]

California will have an adequate supply of natural gas and electricity this winter, with gas prices down slightly from last year, according to the Federal Energy Regulatory Commission’s 2017-18 winter energy assessment. “Fuel and electricity demand likely will be moderate this winter,” Alan Haymes, FERC economist, said Oct. 19. Moderate demand is expected, he said, […]

Utility regulators approved $30 million for energy storage facility subsidies in disadvantaged communities, mostly for institutional systems. The California Public Utilities Commission’s former chief administrative law judge is preparing to sue the agency in court on claims of a retaliatory firing after blowing the whistle on alleged collusion by the commission staff with Pacific Gas […]

The western Energy Imbalance Market produced $39.52 million in benefits in the second quarter of 2017 for the market participants, the grid operator reported July 31. Total benefits since the California Independent System Operator launched the EIM with PacifiCorp in 2014 were $213.24 million, with carbon emissions reductions of 28,700 metric tons from using 67,055 […]

The California Air Resources Board amended its rules for reporting greenhouse gas emissions June 29. The board decided not to include the California Independent System Operator’s energy imbalance market in the rules. Instead, it said it will collect annual information on greenhouse gas emissions related to that market under a formal subpoena process. It made […]

Sacramento Municipal Utility District ratepayers will be paying more for power beginning in 2018. Meeting June 15, the board approved consecutive 1 percent hikes for commercial and agricultural customers in 2018 and 2019, and a one-time hike of 1.5 percent for residential ratepayers in 2018. More “significant,” said Board Member Gregg Fishman, is that the […]

Editor’s Note: This story was updated June 1. For the past several years, the California Air Resources Board and other state agencies have struggled with how to capture emissions related to imports of power into California in the state’s carbon cap-and-trade program. They’ve chiefly focused on a problem originally called resource shuffling. The effort became […]
