Peak Demand occurs essentially during the hottest days of the year (or sometimes the coldest) when electricity use is at its highest and requires all available energy resources to be operating. When demand is at its highest, dirty and very expensive fossil fuel peaker plants that can be quickly ramped on or off are called to operate to meet this demand. Many of these peakers are located in more densely-populated areas and they create significant air pollution and public health problems. In addition, because these plants are very expensive to operate and are paid to be “on-call,” they add a significant cost to everyone’s electric bill, even though they only run only a few hours a year.

Fortunately, solar energy generation is also generally at its peak production during similar hours as peak demand. Therefore, if we get enough solar on the grid, it can play an important role in shaving peak demand – which can reduce the cost of energy for everyone on the grid. And, if the dirty peakers are replaced with solar and/or storage, then the communities where they are located will also benefit.

Join us as we talk with the Clean Energy Group that is piloting a project in New York City to replace fossil fuel peakers with solar plus storage.

They will also share information about the peakers in the Philadelphia metropolitan region, which is one of the top 10 regions affected by fossil fuel peakers in the country. These peakers that are an average age of 50 years old run just 100 hours a year, but spew tons of air pollution (NOx) into the neighboring communities.

We will also provide a primer on peak demand, how it works, and the economics behind meeting peak demand. The Philadelphia Energy Authority will discuss how they are expanding solar energy access Philadelphia, which is a start to replacing peak demand with solar.
