Solar energy can help to address summer peaks of demand

June 28, 2012 1 comment

One of the highest challenges utilities have to face during the hottest season is a huge increase of electricity demand. Customers all around the country, moreover in southern states as Texas, Arizona or California, turn on their air-condition machines at the same time. Utilities are then forced to supply more energy by means of running plants for a short-time, leading to a more expensive generation cost.

Some California utilities already charge electricity depending on a base/peak basis (Time of Use tariff, see previous posts). Solar energy has demonstrated to be able to reduce the electric generation cost on peak times since solar radiation is higher during these hours. If we also consider PV as a distributed generation system, benefits are even more decisive.

The Brattle Group, an energy consultancy, has analyzed “how prices would have been impacted if solar photovoltaic (PV) systems had been added to the generation mix” in Texas last year.
