Net Billing

Net Billing  allows JPS customers who own renewable energy generators such as wind turbines and photovoltaic (solar) systems to generate electricity for personal use. It also permits them to  sell excess energy to JPS at wholesale or “avoided cost” prices set by the OUR. Explain avoided cost . The customer will however buy electricity at the existing rates as outlined in the Tariff Schedule.

NET BILLING versus NET METERING

Net Billing is not the same as Net Metering. Under ‘Net Metering’ the renewable energy (wind or solar) which a customer generates for himself is metered (or measured), so that any excess electricity which is generated can be credited (or banked) to the customer’s account for future consumption. In practice, the meter will spin backward to compensate for any excess electricity generated; or forward, if the customer’s private supply is insufficient, and he/she needs additional electricity from JPS. In effect, the customer is selling electricity to JPS at the retail rate. For information from the OUR about Net Billing, visit the OUR website http://www.our.org.jm.
