Overview

IDACORP, Inc. is an American electricity holding company incorporated in Idaho and headquartered in Boise. Its principal operating business is Idaho Power Company, an electric utility that serves customers in Idaho and Oregon. The holding-company structure also includes IDACORP Financial and Ida-West Energy, giving the group interests beyond the regulated utility's core electricity operations. IDACORP was formed on October 1, 1998. Its corporate identity is closely associated with Idaho Power, whose business is centered on generating, purchasing, transmitting, distributing, and selling electricity. The utility's resource portfolio includes substantial hydroelectric generation, supplemented by coal-fired and natural-gas generation and wholesale market purchases. In 2020, hydroelectric resources accounted for approximately 41.7% of power generated, while market purchases represented approximately 7.4% of the overall electricity supply mix described in the reference material. The remaining supply came from other generating resources, including coal and natural gas. The company operates in the regulated electric-utility sector rather than the oil and gas industry. Its main commercial activity is the provision of electric service, with operations concentrated in the northwestern United States and particularly in Idaho. As a publicly listed holding company, IDACORP provides the corporate structure through which Idaho Power and its affiliated businesses are owned and managed. The company is traded on the New York Stock Exchange under the ticker symbol IDA. IDACORP's positioning is that of a regional electricity infrastructure and utility group. Its business is shaped by the characteristics of regulated power markets: long-lived generation and transmission assets, service-territory obligations, exposure to fuel and purchased-power costs, and the need to maintain reliability while managing the environmental and operational implications of its generation mix. Publicly available reference material identifies hydroelectric power as an important component of the group's supply profile, while also noting continued use of fossil-fuel generation and electricity purchased from external markets. The available reference material provides limited detail on individual executives, consumer-facing campaigns, product launches, acquisitions, controversies, or recent strategic decisions. Accordingly, this entry focuses on the documented corporate structure, formation date, operating geography, electricity business, and generation portfolio. IDACORP should not be confused with unrelated companies or brands bearing similar names; the relevant subject here is the Idaho-based electricity holding company described by the Wikipedia article titled “Idacorp.”

History

IDACORP, Inc. is an Idaho-incorporated electricity holding company based in Boise. The company was formed on October 1, 1998, establishing the corporate framework under which Idaho Power Company and related businesses operate. The reference material identifies Idaho Power as the group's principal subsidiary and describes IDACORP Financial and Ida-West Energy as additional components of the organization. The company's business is rooted in electric utility operations. Through Idaho Power, IDACORP is associated with the generation, procurement, transmission, distribution, and sale of electricity to customers. Its service activity is concentrated in the northwestern United States, particularly Idaho, and is conducted within the operating and regulatory environment of the U.S. electric-power industry. IDACORP's electricity supply combines owned generation with power purchased from external markets. Hydroelectricity is a major part of the portfolio: in 2020, hydroelectric power represented approximately 41.7% of power generated. The company also uses coal-fired and natural-gas generating facilities, while market purchases accounted for approximately 7.4% of the power mix described in the source material. This combination reflects the portfolio of a regional utility that balances hydroelectric resources with thermal generation and purchased electricity. As a public holding company, IDACORP separates the corporate ownership and reporting structure from the customer-facing utility operations carried out by Idaho Power. Its shares trade under the ticker IDA. The supplied reference sources do not provide a sufficiently detailed chronology of later acquisitions, executive appointments, campaigns, product introductions, or major controversies. Those areas therefore remain unpopulated rather than being inferred from the company's general role in the electricity sector.
