The Customer may make a one-time election, in writing, on or before the end of a calendar year, to request that the excess kilowatt-hours be carried forward as a credit from month-to-month in

Net Excess Generation Notes

In the event that net metering is negative such that the eligible Renewable Energy System production is greater than the Customer’s consumption in any month, Utilities will allow excess generation credits (kilowatt-hours) to be carried over and applied to the following month(s).

Any excess generation credits accrued will be credited to the Customer’s account annually at the Small Power Producers and Cogeneration Service Rate Schedule. Customers receiving service under a rate schedule subject to the Standard ECA will have credits calculated at the Small Power Producers and Cogeneration Service Rate Schedule as follows: 18% of the On-Peak Rate plus 82% of the Off-Peak Rate. Customers will be billed the applicable per day Access and Facilities Charges each month regardless of excess generation during that month.

Plans & docs

Site Plan Reqs

Floor/Site Plan A Floor/Site plan must be submitted that shows the location of the following:

• The direction North
• Physical location of all equipment (PV array, inverter, existing Springs Utilities electric meter, REC Meter and AC Disconnect). All metering and disconnect equipment must be located on the same wall as the billing meter.
• The disconnect and meters must all be within line of sight and 10 feet of each other
• Please note that only arrays with an azimuth between 90 degrees East and 270 degrees West will receive a rebate.
•  Standards require billing meter, production meter and AC disconnect to be located in an exterior and accessible location. Solar equipment requires an exterior accessible location and raised to a height within 60-72 inches from grade to center of meter can during installation.
