Black Hills Energy has nearly tripled its investment in its Iowa pipeline system since its last general tariff filing approved over 10 years ago. These investments include the replacement, upgrade and maintenance of more than 2,800 miles of natural gas pipelines and 164,000 system service lines across the state – critical infrastructure needed to ensure the safe and reliable delivery of natural gas to people. clients’ homes and businesses and supporting the growing needs of local communities.

The importance of these investments has been demonstrated by the excellent performance of the Black Hills pipeline system in meeting extraordinary demand during extreme weather events.

The settlement agreement is subject to final review and approval by the Iowa Utilities Board. If approved as filed, the application will shift approximately $ 2.2 million in user revenue to base tariffs and generate approximately $ 3.7 million in additional revenue per year. The regulation proposes a capital structure of 50% equity and 50% debt and a return on equity of 9.6%. Black Hills is seeking new rates effective January 1, 2022, replacing interim rates in effect on June 11.
