The fundamental goal of the MISO Transmission Expansion Planning (MTEP) process is to reduce the wholesale cost of energy delivery for the consumer by addressing local and regional reliability needs. Through the planning process, MISO ensures that the transmission system will enable market efficiency and competitiveness under any resource mix.
The MTEP Report is the culmination of more than 18 months of collaboration between MISO and stakeholders. Each report cycle focuses on identifying issues and opportunities, developing alternatives for consideration, and evaluating those options to determine effective transmission solutions.
The MTEP planning process
- Supports public policy requirements
The proposed Multi Value Project portfolio, recommended to the MISO Board of Directors for approval in December 2011, is the result of more than eight years of process, policy and planning solutions to meet the renewable energy mandates of the states in the MISO footprint. This portfolio will support the annual delivery of more than 41 million MWh of renewable energy to MISO load, while providing economic benefits of 1.8 to 3.0 times the portfolio cost.
- Ensures system reliability is maintained
Reliability projects ensure compliance with all reliability standards and allow new generation to safely interconnect to the transmission network.
- Enhances system economics
Projects currently contained in Appendices A and B are primarily intended to address a reliability issue or need on the transmission system. However, those projects also have potential to create additional value. For example, in MTEP11, a subset of these projects will create 20 to 40 year present value market congestion benefits of $9.1 to $20.6 billion, driving economic benefit-to-cost ratios of 0.9 to 1.0.
- Proactively plans for changing energy policy requirements
MISO examines multiple future scenarios to capture the impact of a wide array of potential policy outcomes. These analyses are intended to provide context and inform state and federal energy policy makers.
- Supports long term resource adequacy
On an annual basis, MISO staff review whether the system has adequate generation capacity to meet its long term system load requirements. These analyses include an assessment of risk factors that may require additional generation build out to serve future demand.
