Idaho Power Company originally filed for incorporation in
Maine on May 6, 1915. It was reincorporated in Idaho as a subsidiary of
IDACORP, Inc on October 1, 1998. In 2018 Idaho Power sponsored the annual "Drive Electric Week" car show event at the state capitol. At the show people can learn about
electric vehicles. Interest in electric vehicles has increased because of changing gas prices, improvements in battery technology, concerns for the environment and federal tax incentives for buying electric vehicles. To respond to customer interest, Idaho Power added tools to its website to guide customers investigating purchasing an electric vehicle. In 2019, Idaho Power set a goal to provide 100-percent clean energy by 2045. In addition to its hydropower facilities, which typically meet almost half its customers’ energy demands, Idaho Power plans additional investments in wind, solar and other clean sources. Clean energy resources are becoming more affordable, which could help Idaho Power accomplish its goal while keeping prices fair. Grid upgrades and battery-storage technology should help maintain Idaho Power's impressive reliability while moving the company closer to its goal. Continued energy efficiency efforts will help. Clean energy initiatives are not new to Idaho Power. In 2009, the company adopted a resolution to reduce carbon emissions. Idaho Power has reduced its carbon emissions intensity — measured in pounds of carbon dioxide () per megawatt-hour — by almost 50 percent since 2005. The company has entered agreements to end participation in two coal plants and is exploring exiting a third — and final — coal plant. ==Hydroelectricity==
