MISO Corrects APPA Report Interpretation

CARMEL, Ind., June 22, 2011 /PRNewswire/ -- APPA's Competitive Market Plan, Update 2011, issued earlier this month, states that "...MISO is in the process of developing a proposal for a centralized forward capacity market resembling PJM's Reliability Pricing Model."  This statement is an inaccurate characterization of MISO's resource adequacy development activity.

Over the last several months, MISO has been working with its stakeholders to improve its current resource adequacy construct to address the following issues of importance:

• Address zonal deliverability concerns and ensure FERC compliance.
• Extend term from a monthly to annual construct to increase efficiencies and better align to existing planning processes.
• Create increased capacity portability and market efficiency across market seams.
• Address retail-state specific issues on load shifting.

While MISO is still working with its stakeholders in anticipation of its scheduled July 15 resource adequacy filing, MISO will be proposing a resource adequacy construct that has distinct differences from PJM's Reliability Pricing Model.  MISO's modified resource adequacy construct is designed to address the unique needs of utilities operating in retail choice states, while respecting and building on the success regulators in traditionally regulated states have built with their integrated resource planning programs.

One of the many key distinguishing features of MISO's proposed resource adequacy construct is the ability of Load Serving Entities (LSEs) to either self-schedule their resources in the auction or "opt out" of the auction entirely by providing evidence of the resources they have to meet their planning resource margin requirement.  Both provisions are designed to allow LSEs the opportunity to continue satisfying their resource planning requirements as they do today.  In other words, MISO's proposed Planning Resource Auction (PRA) creates new options for utilities to meet their resource adequacy requirements while maintaining their current options.

An annual Planning Resource Auction is a key element of MISO's resource adequacy requirement proposal.  The PRA serves several purposes, all related to ensuring that an adequate supply of resources – not an excess supply – is available to meet demand.  The demand forecast for the region will be based on the sum of the forecasts from the LSEs in the MISO region.  The PRA will determine a market-based value for all resources on a zonal basis.  

MISO strives to provide broad regional benefits to its region.  In 2010 alone, these net benefits exceeded $1.25 billion.  The resource adequacy construct modifications currently under development will increase these benefits in the future.
