Net Metering

Washington City adopted a net-metering program, including interconnection procedures, in January 2008.* Net metering is available to residential and commercial customers that generate electricity using photovoltaic (PV) systems or wind-energy systems up to 10 kilowatts (kW) in capacity. At the customer's expense, the municipal utility will provide a single, bidirectional meter to measure the in-flow and out-flow of electricity at the customer's home. Systems are restricted to being sized to provide no more than 120% of the historic maximum monthly energy consumption of the customer. Customers receive credit at the utility's avoided-cost rate for any net excess generation (NEG) at the end of a billing period. The utility takes ownership of all renewable-energy credits (RECs) and other renewable attributes associated with customer generation.

Net-metered systems must comply with the IEEE 1547 and UL 1741 technical standards, where applicable, and must be certified by the utility. The customer must install a manual disconnect switch. Washington City will inspect installations prior to interconnection. Washington City also maintains the right to inspect a customer's system anytime after the initial approval during reasonable hours and with reasonable prior notice. If the city finds the system to be in non-compliance, the city may require the system to be disconnected until compliance is achieved.

Note that Washington City offers a rebate of $1,000 per kW-DC for net-metered PV and wind-energy systems. The rebate is limited to $3,000 for residential systems and $10,000 for commercial systems. The minimum system capacity is 1 kW; the maximum system capacity is 10 kW.

* Utah enacted legislation in 2002 requiring all investor-owned electric utilities and cooperative utilities to offer net metering to their customers. However, the law does not apply to municipal utilities. Washington City offers net metering voluntarily.
