WPPI Energy is seeking proposals from third-party suppliers for short to medium term capacity with or without associated peaking energy rights.
Responses to the Request for Proposals are due by close of business (5:00 p.m. CPT) on Friday, August 8, 2025.
WPPI is a joint action agency serving 51 customer-owned electric utilities (“members”) in Wisconsin, Michigan, and Iowa. These utilities purchase all their electrical requirements from WPPI and supply power to more than 200,000 homes and businesses.
WPPI has a peak demand of approximately 1,060 MW and an annual energy requirement of 5.4 million MWh.
WPPI has a diverse portfolio of power supply resources, including power purchased from other entities, conventional generation owned by WPPI, and renewable resources.
WPPI is a Midcontinent Independent System Operator market participant with about 90 percent of its member load in MISO Local Resource Zone (LRZ) 2, and the remainder in MISO LRZs 1 and 3.
WPPI’s load Commercial Pricing Nodes are WEC.WPPI, NSP.WPPI, ALTW.WPPI, MIUP.WPPI, and UPPC.WPPI. WPPI has generating resources in LRZs 1, 2, 3, 4, and PJM.
Through the RFP, WPPI is looking for up to 150 MW of MISO Zonal Resource Credits (ZRCs) for the summer season (June – August) in any of the next five planning years beginning June 1, 2026, in LRZ 1 or 2.
WPPI will also consider the following variations to the primary interest described above:
• Source of ZRCs: LRZs 3 – 7 or from the MISO PJM External Resource Zone.
• Annual capacity
• WPPI has surplus capacity in fall, winter and spring seasons and would consider an exchange of this surplus capacity for summer capacity.
If associated peaking energy is proposed, the RFP asks respondents to include the following in their response:
- Dispatchability: Specify the scheduling flexibility. Preference will be given to energy resources that can be scheduled at WPPI’s option.
- Energy Pricing: Specify the energy price; e.g., a fixed price, indexed to a fuel and heat rate, etc.
- Energy delivery: Specify the energy delivery point (Supplier is responsible for transmission congestion and loss costs up to the delivery point).
- Scheduling: Scheduling provisions must be compatible with MISO business practices with a preference for the use of MISO Day-ahead Financial Schedules.
WPPI is a member of the North American Energy Markets Association and expects to use either the NAEMA 2019 Power and Gas Master Agreement or the Edison Electric Institute Master Power Purchase & Sale Agreement as the governing agreement for transactions, together with one or more written confirmations.
All credit requirements will be negotiated between WPPI and participating suppliers.
