Electric power Flex Alerts in San Diego

SAN DIEGO (KUSI) — This heat wave could trigger a Flex Alert next week, which means the increased demand for power could put pressure on the state’s power grid during peak demand.

If that happens, the call will go out to SDG&E customers to conserve power.

Whether or not a Flex Alert is called depends on the peak demand for electricity and that demand may come from elsewhere in California.

There’s very little chance this hear wave will interrupt power like we’ve experience in the past, absent some catastrophic event.

But it may still impact San Diego.

"It looks like we have adequate resources available to cover our customers energy. We’re gonna be monitoring the situation closely and if the Cal ISO does call for a Flex Alert on Monday or Tuesday, we will be encouraging our customers to conserve energy," said Hanan Eisenman of SDG&E. 

Eisenman said the utility has spends several months every year preparing for the dog days of summer when the temperature beings to soar.

"We’ve taken a number of steps in order to have adequate resources available for just such a heat wave like this," he said.

"At the moment we’re adequately resourced that means we have our electric generation units on line, our transmission lines are feeding power in to the region so at the moment we have adequate resources," Eisenman added.

Even with the adequate resources, a Flex Alert could be issued for San Diego because we’re all in this together.

"This heat wave is gonna be throughout the region, so let’s say if Los Angeles is very hot and other areas in state are very hot, we might be asked to conserve and help out," Eisenman said.

If other areas of the state are reaching peak demand, that puts the grid under stress and power has to be drawn from other parts of the state.

CAL ISO is the state agency that maintains the power grid and shifts power from one part of the state to another that needs it. The grid is interconnected.

"What happens up north is also important for us because the power grid is interconnected so our conservation efforts down here in San Diego can also relieve pressure further to the north in Los Angeles and elsewhere in the state," Eisenman said.

Here’s what San Diegans are encouraged to do if a Flex Alert is called next week:

  • Conserve energy between 4 p.m. and 9 p.m. That’s peak time for the grid.
  • Set your air conditioner to 78 degrees.
  • No laundry until after 9 p.m.

Anything and everything you can do to converse energy.
