The agreement started with the Vikings first home game versus the Jacksonville Jaguars. Juhl expects to provide 520 MWh of renewable energy over the course of the team’s eight regular season home games.

The California Independent System Operator (ISO) board of governors in September approved a proposed rule to ensure the ISO can keep existing flexible power plants from prematurely retiring if they’re found to be needed for reliability in future years. The need for the ISO to address this issue was highlighted earlier this year when the owners of the Sutter Energy Center informed the ISO it hadn’t been able to secure a power contract and would have to shut down the plant. ISO analysis showed the 525-MW plant would be needed for grid reliability in 2017 and 2018. The California Public Utilities Commission required utilities to enter into power contracts with the Sutter Energy Center for 2012, but the situation prompted changes to the ISO tariff as it currently only provides for capacity compensation under specific circumstances to resources determined to be needed in the next operating year. The approved at-risk of retirement provision allows the ISO to contract for capacity determined to be needed for reliability reasons two to five years in the future. The price for the capacity is based on the resource’s “going-forward” costs. The ISO would only use the special designation after the plant operator has made a good faith effort to secure a utility contract.
