How does NEM work?
The NEM program uses a bi-directional meter to measure and/or track the “net” difference between the amount of electricity you produce and the amount of electricity you consume during each billing period. This can be accomplished on a cumulative basis or on a time-of-use basis, depending upon your rate schedule. At the end of each billing period, you may receive a credit for any energy you have generated that is in excess of the energy you have consumed. If your energy consumption is greater than your energy produced you will be billed for the net difference. You will be billed monthly and required to pay for certain other applicable charges whether or not you are a Net Energy Metering customer. For additional details, please refer to the NEM Fact Sheet (PDF).
