3 reasons Texas’ electric grid survived a summer that pushed its limits

As the hot summer approached, Texas leaders expressed concern about potential blackouts and brownouts. Yet, thoughtful planning, a functional electricity market and clean energy helped ensure the lights stayed on.

Power outage concerns

Hotter temperatures and continued population and commercial growth drove record electricity demand this past summer. Additionally, in early 2018, Luminant (now Vistra) shut down three large coal plants – all inefficient and highly-polluting – with a combined capacity of 4,200 megawatts (MW).

The shutdown of these power plants and other changes in the electricity market initially led the state’s electric grid operator, the Electric Reliability Council of Texas (ERCOT), to forecast few electricity-making resources would be available beyond the amount customers would likely demand.

A regionalized energy grid creates a home for California’s wasted renewables

By Andy Bilich, Lauren Navarro

These days, California’s renewable energy records are regularly broken.

During the summer solstice on June 21, California utility scale solar power set a generation record with solar producing equivalent to about 16 percent of all electricity consumed during the day.

And earlier this year, on April 27, California set two renewable energy records for both instantaneous solar generation: about 10.5 gigawatts), and instantaneous renewable generation: 73 percent of the state’s total electricity demand came from renewable energy.

With renewables deployment poised for more growth, it’s likely even these new records will be surpassed sometime soon. However, to ensure the state’s investment in clean energy is put to use, and not wasted, California has some work to do. Read More »

Resilience proceeding gives FERC a chance to advance gas-electric coordination

Last September, the U.S. Department of Energy (DOE) started a conversation on resilience, asking the Federal Energy Regulatory Commission (FERC) to provide new revenues and guaranteed profits to the owners of old, inefficient coal and nuclear power plants to compensate these resources for certain reliability and (undefined) resilience attributes.

FERC swiftly disposed of that proposal in a January 8 order, finding that it was not warranted and would run counter to its pro-market regulatory model. FERC then asked all of the Regional Transmission Operators (RTOs) and Independent System Operators (ISOs) to explain how they are evaluating and addressing resilience within their respective markets.

The most important thing California can do with its clean energy could be to share it

Not often is running the electric grid as simple as applying lessons from childhood. Right now it is ─ California is learning to share with its neighbors. A bill currently in front of the Legislature from California Assemblymember Chris Holden, AB 813, aims to build a better trading platform to share California’s extra solar power with nearby states like Oregon, Washington, and Nevada, which would then share their extra wind, solar, and hydropower resources with California.

It is like the lunch table you sat around as a kid – one where you can trade that banana pudding that overflows at your house for one of your neighbor’s chocolate chip cookies. It’s a delicious deal, where everybody wins.

That deal just got better. Holden’s office yesterday released new language which represents an important, positive step in the process of creating a regional electric grid for the West. This includes key requirements and protections to ensure a regional grid lowers harmful greenhouse gas emissions and supports California’s climate and energy goals – helping the state and its neighbors to move towards a low-carbon future.
