Ameren Corp. has axed an build-transfer deal with EDF Renewables North America for a 157 MW wind farm in Atchison County, Mo., citing transmission upgrade costs.
Ameren signed the deal for the the Brickyard Hills wind farm last year and it was supposed to be coming online in 2020 (PFR, 10/24).
"Significant upgrades would have been required on the transmission system to accommodate this project, leading to unacceptably high costs,” said Michael Moehn, chairman and president of Ameren Missouri, in a statement. "While it is disappointing we will not be moving forward with this project, we remain focused on seeing our other, larger projects through to the finish line."
The company aims to own at least 700 MW of new wind generation by the end of 2020, and has agreements in place for two other projects—Terra-Gen's 400 MW High Prairie wind farm in Adair and Schuyler counties (PFR, 5/22/18), which has the approval of the Missouri Public Service Commission, and a 300 MW facility being developed by Tradewind Energy in Atchison County, which is awaiting approval.
These two projects represent a total investment of about $1.2 billion.
Ameren Missouri also plans to add 50 MW of solar generation by 2025, rising to 100 MW by 2027, and to retire more than half of its coal-fired plants in the next 20 years, beginning with the Meramec Energy Center in 2022.
