Z2 Resettlement

Z2 is an attachment to SPP’s tariff, approved by FERC, that outlines a process to compensate utilities, generation owners, and others within the SPP footprint for transmission upgrades that enhance grid capabilities. These upgrades enable access to increased electricity generation, benefiting the overall system.

SPP is actively working to comply with a Federal Energy Regulatory Commission (FERC) mandate to resettle invoices related to specific transmission upgrades. This complex task has posed significant challenges for both SPP and its members, but a resolution is anticipated in the near future.

The issue has evolved over the past 15 years and is expected to involve the resettlement of several hundred million dollars in electricity purchases. The process involves navigating a complicated mix of legal, financial, and engineering factors that need to be restructured in a way that satisfies court requirements while remaining feasible to implement. SPP is treating this matter with the utmost priority, with multiple departments and numerous staff members dedicated to finding a solution.
