As California moves toward a 100-percent clean power supply, the rapid growth of wind and solar power has many people wondering how a modern, 24-7 society will still have reliable power. After all, wind and solar are only available when the wind is blowing and the sun is shining. 

After decades in the slow lane, California's automobile manufacturing market is accelerating with the advent of the electric vehicle, but EV implementation is not without twists and turns as the California Public Utilities Commission lays out plans for how billions of dollars will be investe…

California's retail electricity rates are high. However, some argue it's not about rates but the bills that electricity customers pay, and the Golden State isn't doing so bad in that department. Coloring the conversation is the fact that energy-efficiency measures, weather, usage and income …

One of two office spaces of MCE Community Choice Energy, more than a decade after it was the first community choice aggregator to be formed, is nestled into downtown San Rafael, a city of about 60,000 residents in the North Bay region of the San Francisco Bay Area. A visit to the office by C…

Safety practices at investor-owned utilities in California were supposed to have a stronger link to the salaries of their top executives with the passage of AB 1054, wildfire-utility legislation that passed last year. But the plans filed by IOUs with the California Public Utilities Commissio…

Assm. Chris Holden (D-Pasadena) opened a Jan. 22 hearing in Sacramento with a rather grave assessment of the state of California electricity service, mentioning projected capacity shortfalls, high retail rates, power shut-offs and the bankruptcy of Pacific Gas & Electric.

A state legislator representing Oakland, along with other Democrats, introduced California's "Green New Deal"—a bill that would accelerate the state's efforts to combat climate change and link those efforts to a sweeping set of reforms tackling some of society's most difficult and long-lasti…

Going into 2020, a need for flexible power resources to ramp up the grid each day as solar generation wanes is largely confined to California, but it is a challenge that will expand across North America over the next decade, according to the entity responsible for the reliability of the bulk…

The public-safety power shut-offs have ended, but the nights are still long . . . and so we present our annual tradition of energy-themed carols to help see everyone through. NewsData will be closed the week of Dec. 23 through Dec. 27, and we will resume our usual publishing schedule the wee…

The finding Oct. 24 that a Pacific Gas & Electric transmission tower might be the source of yet another disastrous wildfire, coupled with serious fires in Southern California, made for a brutal week for grid users and utilities, who were already in the grip of a widespread public-safety …

The outrage expressed by Gov. Gavin Newsom over Pacific Gas & Electric's widespread power shut-off last week in Northern California, as well as the response from the state's top energy regulator, showed a curious reaction and allocation of blame for a state-government-approved event that…

It was the best of times, it was the worst of times for two natural gas-fired power plants in Yuba City, a working-class city with about 65,000 residents in the northern Central Valley.

In the wake of marches around the globe for action on climate change, Gov. Gavin Newsom took to a national stage to spread the word about California's climate success story. But a closer look at some of his victory pronouncements reveals a much more chaotic situation on the ground than his c…

Climate change—for years a focus in California—is shaping up to be a central theme in a U.S. presidential election for the first time and was the topic this week of a grueling seven-hour public town hall on the CNN television network among Democratic candidates.

As excited as energy storage developers are about new prospects as a result of the Federal Energy Regulatory Commission’s Feb. 15 energy storage rule , it will now fall to grid operators around the country to craft their own tariffs allowing storage to participate in wholesale markets.

Leadership of the Los Angeles Department of Water & Power drew a strong backlash this week over a decision to delay approval of a 25-year power-purchase agreement with a commitment of up to $1.5 billion to replace natural gas-fired power plants with a massive solar/battery storage project.

Every year we take a one-week break at year’s end, so California Energy Markets will not be published on Friday, Dec. 30. Our next issue will appear Friday, Jan. 6, 2017. We wish all of you Happy Holidays and best wishes for the new year, and here present another annual tradition: energy-the…

California offshore waters are known for surfers, sea lions and big waves, not ocean-bound wind turbines, but anticipation is high as a new leasing process for offshore sites by the federal government begins next year.

Arizona Public Service, which has 2,500 MW of transmission transfer capacity with CAISO, is having quite a large impact on the Western energy imbalance market.

With the shortest day of the year approaching, this is a good time to review some new solar-technology developments that may brighten our future horizon. Two of them have to do with reducing the weight of photovoltaic equipment, while another is an advance in solar-roadway technology.

CAISO’s market rules for how to allocate the cost of transmission in a regional grid have all the headaches of a gigantic dinner bill split among dozens of parties. With so much food on the table, it’s possible to have free riders, cost shifting, and an inequitable split.

In a recent post on the Energy Institute at Haas blog, James Bushnell took issue with a Los Angeles Times article that noted Californians are already paying billions for excess generation capacity the state doesn’t need. As a result, California’s retail electricity prices are about 50 percen…

No one died or was seriously injured in the April 21 daylong blackout in San Francisco, which was good news. But the incident highlights troubling conditions at some Pacific Gas & Electric substations in San Francisco.

Executives with California’s investor-owned utilities in second-quarter conference calls voiced support for Gov. Gavin Newsom and the AB 1054 legislation he signed in July that swiftly and dramatically reduced their financial risk from wildfires, shoring up their bottom lines.

Southern California Gas Co. is facing pressure from some environmentalists and elected officials to close the Playa del Rey gas storage facility in Los Angeles, a situation reminiscent of another big headache for the company—the controversy over Aliso Canyon.
