The Midwest ISO announced its annual Value Proposition study for 2010, which reflects the quantitative and qualitative benefits provided to the region through its grid reliability and efficiency measures. The study identifies US$1.3 billion to $1.6 billion in annual benefits to the region. Over the next 10 years, the Midwest ISO estimates the region could receive between $11.2 billion and $14.6 billion in benefits on a net present value basis.

The analysis shows realized annual benefits ranging from $650 million to $875 million from the Midwest ISO's greater grid reliability and efficiency measures. The study also identifies benefits of $600 million to $760 million from reduced generation investment. The generation investment benefit will be realized as load grows or current generating infrastructure retires due to age or environmental restrictions.

Like prior Value Proposition studies, the Midwest ISO's analysis included input from all interested stakeholders in an open and transparent process. The 2010 study measured value drivers in which the Midwest ISO's members and their customers are benefiting from the regional transmission organization's operations in the following areas: improved reliability, market commitment and dispatch, wind integration, generation investment deferral and demand response.

The Midwest ISO ensures reliable operation of and equal access to high-voltage power lines in 13 U.S. states and the Canadian province of Manitoba.
