Explanation of Ten Sample Load Profiles

Profile 1 is based on a device rated at 1 kW, operated only one hour during each summer month (June, July, August, and September) when the entire facility is already operating at its highest peak demand level. This added load increases the peak demand level for the month by 1 kW. Therefore, there is a peak demand charge for that 1 kW in each of the 4 summer months. It also adds 1 kW to any applicable peak demand ratchet level. Under Rate 1, for instance, the effect of this 1 kW is a monthly

Renewable energy is energy that is generated from sunlight, rain, tides, geothermal heat and wind. These sources are naturally and constantly replenished, which is why they are deemed as renewable.
