Thayer Executive Director Alaska Energy Authority Community and Regional Affairs Committee January 30, 2020 Who We Are Created in 1976 by the Alaska Legislature, the Alaska Energy Authority (AEA) is a public corporation of the State of Alaska governed by a board of directors with the mission to “reduce the cost of energy in Alaska.” AEA is the state's energy office and lead agency for statewide energy policy and program development. Alaska Energy Authority 2 What We Do Energy Planning –In collaboration with local and regional partners, AEA provides critical economic and engineering analysis to plan the development of cost effective energy infrastructure. Grants and Loans –AEA provides loans to local utilities, local governments, and independent power producers for the construction or upgrade of power generation and other energy facilities. Railbelt Energy –AEA owns the Bradley Lake Hydroelectric Project and the Alaska Intertie. These assets benefit Railbelt consumers by reducing the cost of power. Renewable Energy –AEA provides renewable energy and energy efficiency grants, analysis, and expertise to benefit Alaskans. These include hydro, biomass, wind, solar, and others. Power Cost Equalization –The Power Cost Equalization Program reduces the cost of electricity in rural Alaska for residential customers and community facilities. Rural Energy –AEA constructs bulk fuel tank farms, diesel powerhouses, and electrical distribution grids in rural villages. AEA supports the operation of these facilities through circuit rider and emergency response programs. Alaska Energy Authority 3 Our Projects AEA works with its Alaska partners and stakeholders to provide reliable and affordable energy solutions.

Commonly measured as Megawatt -hours (MWh) or kilowatt-hours (kWh). House on the Alaska Railbelt may use 500-600 kWh per month energy.
