LES encourages and supports cost effective, small power production of electricity by customer-owned renewable generation facilities.

Overview of the generator interconnection process

LES customers may wish to interconnect a customer-owned generator in parallel with the electric system. FERC-defined qualifying facilities, which include cogeneration facilities and renewable energy generators such as wind and solar, have specific requirements for interconnection with LES. To operate in parallel with LES, the qualifying facility must meet all applicable LES interconnection requirements including, but not limited to, submission of an interconnection application, as well as entering into an interconnection agreement. Nonqualifying facilities, which include emergency or backup generators, are generally only allowed to operate in parallel with LES for periodic testing purposes. On a case-by-case basis, LES may allow a customer to contract to operate in parallel for more than testing purposes under agreement with LES to generate only at times of LES’ request. All nonqualifying facilities operating in parallel for both periodic testing purposes or for more than testing purposes must meet all applicable LES interconnection requirements including, but not limited to, submission of an interconnection application, as well as entering into an interconnection agreement if required.

The process for interconnecting to the electric system within the LES service area follows:

  1. Customer determines the type, size and site for a generator.
  2. Customer applies for a building permit and completes an Application for Electric Service with the Authority Having Jurisdiction.
  3. Customer completes and submits an Application for Review of Interconnection with LES.
  4. Customer installs the generator according to the applicable requirements after receiving a notice to proceed from LES.
  5. Customer completes and returns to LES one of the following forms:
    1. Net Metering 25 kWAC or less Agreement for Interconnection.
    2. Renewable Generation up to 100 kWAC Agreement for Interconnection.
    3. Cogeneration and Small Power Production Parallel Operation, Power Sales, and Interconnection Agreement.
    4. Generating Facilities in Excess of 100 kWAC Interconnection Agreement.
    5. Agreement for Non-Qualifying Generation – Emergency and Standby (Types 3 and 4).
  6. LES inspects the generator interconnection. If acceptable, customer may interconnect with the electric system.

These LES avoided costs of generation are displayed on this website as required by the Federal Energy Regulatory Commission, Regulations Order 69, 18 CFR Part 292.302. Avoided costs of generation are the costs saved by reductions in retail energy use.

Net metering

Renewable generation with production capacity of 25 kWAC or less, in conjunction with a retail load. Renewable generation includes electric generators powered by methane, wind, solar, biomass, hydro or waste technologies.

Net metering is a billing arrangement where residential and business customers who produce their own energy from renewable sources can get a credit on their electric bills for extra energy that flows back into our distribution system. We measure the electricity you generate from solar panels, a wind turbine or other renewable generators by a special meter that measures both the electricity you use and the electricity you produce. The energy you generate is used to offset an equal amount of power supplied by LES in the billing period. Energy produced in excess of your need (or net kilowatt-hours) is credited to your bill at a renewable rate based on our residential retail energy rate.

Renewable generation

Renewable generation with production capacity of greater than 25 kWAC and less than, or equal to, 100 kWAC. Renewable generation includes electric generators powered by methane, wind, solar, biomass, hydro or waste technologies.

LES’ renewable generation rate is a billing arrangement where customers sell energy to LES from renewable generators. The same types of generators that qualify for net metering also qualify for this renewable generation rate. All energy produced by these generators will be purchased at the renewable rate.

Cogeneration or small power production

Rates and agreements will be developed on a case-by-case basis.

Cogeneration and small power production facilities with production capacity of 100 kWAC and less that qualify under the guidelines for implementing Public Utility Regulatory Policies Act of 1978 (PURPA) Sections 201 and 210 as adopted by the LES Administrative Board.

Emergency generator

Customer-owned emergency or standby generating facilities that do not qualify under the guidelines for implementing Public Utility Regulatory Policies Act of 1978 (PURPA) Sections 201 and 210 as adopted by the LES Administrative Board. This type of generation is generally only allowed to operate in parallel with LES for periodic testing purposes.
