Why are energy prices higher in the summer?

The kWh or unit cost of energy is different in winter and summer regardless of your price plan. The price you pay rises and falls with the demand for electricity. During the coolest months, customer usage, generation costs and the price you pay are lowest. During the hottest months, customer usage skyrockets and generation costs to meet peak demand are highest.
