Grant County Wind

Grant County Wind

Aspenall was founded in 2007 in Puerto Rico with the goal of advancing community-scale and decentralized generation renewable energy projects. We developed, installed, and operated the first industrial-scale wind project on the island, providing the power from a 500 kW wind project to Bacardí Corporation's distillery in Cataño under a power purchase agreement (PPA). The project was transferred to Bacardí after ten years of operation. We also negotiated PPAs with a number of private and public entities on the island.

With the increasing fiscal issues facing the Puerto Rican government and the entrenched resistance of the Puerto Rico Electric Power Authority to the development of decentralized renewable energy projects, we shifted our focus away from the Caribbean. In the Midwest, we have found the supportive regulatory environment and actively engaged community necessary to foster the development of renewable decentralized generation.

In 2014, we purchased the Grant County Wind Project, a 20 MW wind energy project located in western Minnesota, and developed pursuant to that state’s Community Based Energy Development Program (C-BED).

In 2018, we reached commercial operation on the Kimball Wind project, our largest project to date, a 30 MW wind energy generation plant located in Kimball, Nebraska. The project provides power to the Municipal Energy Agency of Nebraska through a PPA. 

Our headquarters are in Minneapolis Minnesota, since 2017, and we are actively pursuing more projects in the Midwest
