MISO Energy Storage Study Phase 1 Report - Utility Wind ...

THE MISO PLANNING ENVIRONMENT
• Multi Value Projects (MVP): meeting Attachment FF requirements to provide regional
public policy economic and/or reliability benefits
MTEP projects are prioritized based on their documentation, justification and approval. Each
annual MTEP plan lists projects in appendices according to these priorities. Projects start in
Appendix C when submitted into the MTEP process, transfer to Appendix B when MISO has
documented the project need and effectiveness, then move to Appendix A after approval by the
MISO board of Directors.
MISO planning efforts expanded in 2010 to meet the challenges associated with integrating
renewable energy. The MVP project category represents new transmission that provides regional
public policy economic and/or reliability benefits. The MVP category requires extensive analysis
and modeling to determine which transmission expansions best meet regional public policy goals
under different future economic and regulatory scenarios. The Regional Generation Outlet Study
(RGOS) and the Regional Economic Criteria and Benefits (RECB) task force were created to
determine the transmission needed to meet MISO stakeholder RPS policy goals as well as how to
fairly allocate costs associated with these projects.
The RGOS analysis includes refining future generation and load scenarios, and modeling
transmission values under a full range of future possibilities. The study produced three reliable
transmission portfolios based on different scenarios. Elements common between these three
portfolios, and common with previous reliability, economic and generation interconnection
analyses were identified to produce a 2011 candidate MVP portfolio.
The 2011 MTEP studies 5 evaluate the candidate MVP portfolio to identify near-term, robust
transmission solutions that fulfill multiple transmissions and reliability needs. This represents a
first step towards a truly regional transmission solution to integrate wind resources into the
MISO footprint.
The future resource and load planning scenario detail used during the MTEP11 MVP analysis is
presented here to explain the model environment that MISO transmission planners currently use
to evaluate wind integration projects. The Energy Storage Study uses similar future scenarios and
assumptions to model the additional impact that using energy storage might have on the MISO
resource and load plan.
The MTEP11 MVP modeling analysis uses the following alternative future scenarios and
parameters:
• Future Policy Scenarios
o Business as usual with continued low demand and energy growth (assumes that
current energy policies will be continued, with continuing, recession-level low
demand and energy growth projections).
o Business as usual with historic demand and energy growth (assumes that current
energy policies will be continued, with demand and energy returning to prerecession
growth rates).
