NSP – RFP for Seasonal Resource Adequacy Capacity

Northern States Power Company (NSP) is seeking offers for MISO Seasonal Zonal Resource Credits (ZRCs) for the 2027/28 MISO Planning Year. This solicitation is posted on behalf of NSP by the North American Energy Markets Association (NAEMA). NSP prefers capacity located in MISO Local Resource Zone 1 (LRZ 1) but will consider offers from other MISO Local Resource Zones. For offers outside LRZ 1, bidders must identify the source LRZ and describe the proposed pricing or settlement structure. NSP prefers structures that either satisfy its LRZ 1 resource adequacy requirements or financially settle based on differences between the applicable source zone and LRZ 1 clearing prices.

Short-term offers may cover one or more seasons of the 2027/28 MISO Planning Year. Long-term offers may consist of seasonal ZRC commitments, capacity from identified generation resources, or other capacity structures proposed by the bidder. Long-term offers may cover terms up to five years and may begin in the 2027/28 Planning Year or a later Planning Year. The requested minimum long-term bid quantity is 10 MW, with a preferred bid size range of 25 to 75 MW.
