In no case will the allowable nameplate generating capacity rating exceed 50 kW. 2.2.7 Charges for energy delivered by MEC in excess of the energy flowed back onto the system shall be billed monthly at a retail rate. Excess kWh’s may be banked beyond the monthly billing period. (banking is a method of accounting, within an annual billing period, for energy produced for export into the distribution system for later use at that customer’s service); 2.2.8 MEC may annually true-up (zero) banked kWh’s. The true-up will occur following the April billing cycle.

SLD Reqs: One-Line diagram showing the configuration of all Small Generating Facility equipment, current and potential circuits, and production and control schemes.

Install Reqs: No PM, but please be aware our meter will only read the energy being transferred onto our system. Most people are using power as they generate so what they will see on their bill won’t necessarily reflect what they are producing.
