Net metering systems allow power consumers to connect on-site generation sources to the utility grid. When the on-site generation source is producing energy, the consumer uses this energy instead of purchased power. When the on-site generation source is not producing energy, the consumer uses power purchased from the utility.

SLVREC offers a manual for net metering here:
Net metering for systems 25kW and less

The application for net metering is here.

Under net metering, a utility company may either purchase power produced in excess of the consumer’s needs or credit the consumer for power fed back into the electric grid. SLVREC’s policy is based upon current state law. Copies of the policy are available from SLVREC customer service. In general, those who net meter must:
• Use as an energy source solar, wind, biomass or hydropower resources.
• Have the facility on premises owned, operated, leased or otherwise controlled by the Customer-Generator.

Members must pay an inspection fee prior to connection of their net metering service to ensure that their system meets all appropriate safety codes and does not adversely impact the cooperative’s distribution network.

Up to the point where the generation system produces power in excess of on-site needs, the cooperative will compensate the member by running the member’s electric meter in reverse. However, if during a billing period, the net metering system produces more energy than the member uses, the excess energy will be purchased by the cooperative at the SLVREC’s avoided cost. The avoided cost is defined as the average cost of wholesale power for the previous calendar year.

Members with net metering systems are still required to pay monthly minimum charges. These charges go toward system maintenance, meter reading and other overhead expenses associated with keeping the cooperative’s distribution infrastructure available to members.

Members who are interested in installing a net metering system are encouraged to contact the cooperative first to discuss interconnection requirements and system needs. Net metering systems can be expensive. SLVREC can help determine an appropriately-sized system and provide information on installation concerns.

Net metering offers much promise. However, maintenance costs, current state law insurance requirement expenses and installation costs can make installing a net metering system prohibitive. SLVREC offers members an alternative way to use renewable energy through a green power program. This program offers members a way to ensure that the power they use comes from renewable sources.

Under the cooperative’s green power program, members pay a small premium for every 100 kWh block of renewable energy they purchase. SLVREC turns this money over to their power provider, Tri-State Generation & Transmission Association, who in turn uses it to purchase power produced by renewable generation sources. For every 100 kWh block purchased, 100 kWh of green power enters the electric grid. This program offers every member a cost-effective way to use renewable energy.

Customer service representatives can answer questions on the green power program, or help members contact SLVREC net metering specialists. Call for more information. The Governor’s Energy Office may be also able to provide information on net metering in Colorado. (http://colorado.gov/energy)

The diagram above outlines the essentials of a net metering system.
In most locations within the Valley, solar panels offer the most promise
for consumer generation. With photo-voltaic generation systems,
an inverter converts DC power to AC power. Power feeds
into the member’s electric service panel.
A disconnect switch protects both the
homeowner and utility workers. The meter records
both member use and member generation.
