BIZ-POWERGRID-TEXAS-BUFFETT-GET

After a brutal storm knocked out about half the power to Texas last month, over 4 million families and businesses suffered in the cold and dark. Berkshire Hathaway has proposed a way to boost reliability on the grid, but it comes at a cost.

DALLAS — Berkshire Hathaway Energy, part of Warren Buffett’s giant holding company, is proposing a fix for the Texas electric grid, which suffered widespread outages after a brutal storm last month.

But the plan includes a major change to Texas’ deregulated power market, including guaranteed payments for the extra capacity.

The company, to be known as Texas Reliability Corp., is offering to invest $8.3 billion in new generation powered by natural gas, along with gas storage. That would add about 10,000 megawatts of reliability plants to ERCOT, the grid that sends electricity to about 90% of Texans, the company said in a slide deck presentation.

In an event such as last month’s outages, the Berkshire plants would supply at least half the load that was shed from the system, a slide said.

Berkshire executives were in Austin last week to lobby lawmakers on the plan.

In its slides, Berkshire said the investment would protect ERCOT from future extreme weather events and would limit power outages to three-hour intervals. During last month’s weather crisis, some people were without electricity for several days.

But the proposal is likely to face opposition, especially from heavy industrial users of electricity. In general, they want to pay for power they use, not power pledged for emergencies.

Texas generators also would want to get in on the action, and one observer called the Berkshire proposal “a one-company capacity market.”

Berkshire proposes that consumers pay a fixed fee to cover the project costs, plus a rate of return approved by the Public Utility Commission. That would be similar to how the state regulates transmission and distribution lines, but not generators.

ERCOT would control the power plants under the proposal and the units would run intermittently for testing and when needed for emergency supply, the company said.

This “fixed-cost solution,” as Berkshire called it, could be implemented in time for the winter of 2023. While it would introduce added costs, it would also reduce uncertainty, Berkshire said.
