Community Solar Pilot Program

Idaho Power submitted a proposal to the Idaho Public Utilities Commission (IPUC) to launch a Community Solar Pilot Program.

Corporate Headquarters' Photovoltaic Array

Our corporate headquarters' photovoltaic (PV) array, installed in 1994, is a 25.0 kilowatt (kW DC) rooftop solar system.

This system has 90 individual panels (or modules) and five inverters with a system capacity of 20.5 kilowatts (kW AC). The electricity produced is supplied directly to the building and provides enough energy to operate all the computers on a single floor – just over 100 kilowatt-hours per day.

The amount of electricity generated varies significantly depending on the season and amount of sunlight, as you can see from these graphs of sunny day generation versus cloudy day generation.

Solar in Idaho Power’s Daily Operations

Solar Trailer

Idaho Power uses small PV panels in its daily operations to supply power to equipment used for monitoring water quality, measuring stream flows and for operating cloud seeding equipment.

In addition to these PV installations, Idaho Power:

  • Participates in the Solar 4R Schools Program
  • Has a mobile solar trailer to supply power for concerts, radio remotes and other events
  • Operates a 200-watt solar water pump used for demonstrations and promotion of PV technology
  • Donated a 2.7-kilowatt array (36 75-watt PV modules) to the Foothills Learning Center in 2005
  • Owns a Solar-Enhanced Lighting™ system in one of its downtown Boise parking lots, in partnership with Boise-based Inovus. The system was installed in July 2013 and is designed to generate as much energy during the day as the lights consume at night while illuminating the parking lot.
  • Participated in the installation of solar panels at Celebration Park, near Melba, Idaho. The panels supply electricity to the park’s outdoor lighting and visitors center, with any additional generation going back to the electrical grid.
