CAISO Adopts Energy Storage, Imbalance Market Rules to Improve Grid Reliability

The California Independent System Operator has approved three reliability improvements for storage management that are set to take effect this summer when extreme heat could cause a spike in demand.

Stage 2 Power Emergency, Flex Alert in Effect

It is the eighth day in a row that a flex alert has been called in California, reports NBC 7’s Melissa Adan.




State Warns of Possible Rolling Blackouts Amid Scorching Heat Wave

The operator of the state’s power grid warned residents Tuesday to prepare for possible rolling blackouts, as a drawn-out heat wave reaches its peak and drives electricity demand to an anticipated record level.


VIDEO: The heat wave is stretching into the seventh day and relief is not expected anytime soon which means the demand for energy is straining the grid. The California Independent System Operator has issued a Flex Alert asking residents to conserve energy during peak use but as KPBS reporter Alexander Nguyen shows us it is also tapping other sources for energy.


CAISO Approves Nearly $3B of Transmission Projects to Prepare for California’s Clean Energy Goals

The California Independent System Operator approved a transmission plan Thursday that includes 23 projects, estimated to cost nearly $3 billion, to cope with the dramatic increase in renewable generation and forecasted load growth in its footprint.

First Steps Taken to Make Pumped Hydro Energy Storage Project at San Vicente Reservoir a Reality

With an $18 million boost from the state, a major energy storage project using hydroelectric power is taking shape at the San Vicente Reservoir, nestled in the Cuyamaca Mountains near Lakeside.

The long talked about San Vicente Energy Storage Facility — proposed by the city of San Diego and the San Diego County Water Authority — received the funding earlier this month when Gov. Gavin Newsom signed the state budget. The $18 million will be spent to tackle some of the preliminary work needed to make the “pumped hydro” project a reality, such as initial design, environmental reviews and federal licensing.

“We believe the project is a critical component to meeting the state’s needs for integrating renewables” into the power grid, said Gary Bousquet, deputy director of engineering at the County Water Authority.

The Energy Transition: ‘The Days When People Couldn’t Pay Attention to Their Electricity Supply are Over’

California is going through a dramatic energy transition. The state has set a goal to derive 100 percent of its electricity from carbon-free sources by 2045 and last week Gov. Gavin Newsom directed state agencies to look at moving the target up to 2035.

That means finding a way to eliminate greenhouse gas emissions from the state’s power grid while at the same time ensuring the power system remains reliable and affordable.

It’s a balancing act.

Opinion: Can We Have a Power Grid That is Both Renewable and Reliable?

With more than 4 million acres burned this year – shattering a state record – California’s wildfire season came with a wicked ferocity, along with the climate-induced crises of crippling heatwaves and forced power outages.

Report: A Combination of Factors Caused California’s Rolling Blackouts in August

How a Plan to Save the Power System Disappeared

On August 14, 2018, Joshua Novacheck, a 30-year-old research engineer for the U.S. National Renewable Energy Laboratory, was presenting the most important study of his nascent career. He couldn’t have known it yet, but things were about to go very wrong.

As California Burns, the Winds Arrive and the Lights Go Out

New wildfires ravaged bone-dry California during a scorching Labor Day weekend that saw a dramatic airlift of more than 200 people trapped by flames and ended with the state’s largest utility turning off power to 172,000 customers to try to prevent its power lines and other equipment from sparking more fires.
