The top US grid operator asks large users to reduce demand during warm weather

PJM Interconnection, the US electric grid operator, called on 'large energy consumers' in 13?states?to reduce their consumption?on a Thursday as high temperatures fueled power demand and threatened blackouts.

PJM is the largest regional grid operator in the US, covering the Mid-Atlantic region and the Midwest. The system reported that it had experienced power outages of about 36,000 megawatts, reducing the supply of electricity.

PJM's "demand -response program" pays customers who temporarily reduce power or?cut it when asked to, in order to deal with rolling blackouts.

As transmission and power plant operators enter maintenance season, the demand for cooling systems from homes and businesses is strained by temperatures above average.

In recent years, the demand for electricity in PJM has outpaced new supply and increased energy margins.

The US Department of Energy granted PJM’s request for a temporary waiver on environmental permit restrictions. This will allow 'energy-intensive data centres to switch over to backup generators which can be'more polluting.

PJM is the largest data center hub of the world in "Data Center Alley" in?northern Virginia. PJM also services a number of?new hubs that are booming in states such as Pennsylvania and Ohio.

As part of its emergency measures, the operator may also restrict?exports.
