Midwest ISO Board Approves MTEP10 Endorsing 231 New Projects

CARMEL, Ind.,Dec. 2, 2010 /PRNewswire/ — The Midwest ISO Board of Directors
approved today the 2010 Midwest ISO Transmission Expansion Plan (MTEP10), which
recommends the addition of 231 new projects over the next decade to further
increase regional reliability, grid efficiency and enable public policy
fulfillment.

In approving the plan, the Board commended the Midwest ISO’s transmission
owners, regulators and other stakeholders for their active engagement with
Midwest ISO in producing MTEP10, which represents a total new investment of more
than $1.2 billion in transmission infrastructure within the Midwest ISO
footprint through 2020.

“MTEP10 exemplifies how implementation of a value-based planning approach to
infrastructure development can maximize value for the region,” said John Bear,
president and CEO of Midwest ISO. “These recommended projects are tribute to the
collaborative efforts of all stakeholders to further our collective goals of
increasing reliability, decreasing energy productions cost, decreasing energy
losses associated with transmission, addressing energy policy goals, and
potentially reducing reserve margin requirements.”

MTEP10, the seventh edition of the regional transmission plan, is a culmination
of more than 18 months of collaboration and ongoing dialogue between regional
stakeholders and the Midwest ISO planning staff. In addition to benefits
realized from increased system reliability, a $4 billion subset of projects
targeted at reliability and similar needs is projected to provide a potential
annual benefit of $825 million from market efficiencies beginning in 2015.

The MTEP 10 planning cycle also includes the Michigan Thumb Loop project
approved earlier in the year, a $510 million project intended to address
integration of renewable energy for the region and the first regional project
expected to fall within Midwest ISO’s Multi-Value Project (MVP) cost methodology
currently pending before the Federal Energy Regulatory Commission. The project
was reflected in the Midwest ISO’s collaborative Regional Generation Outlet
Study (RGOS), which identified where to locate wind zones, along with the
transmission required to interconnect them, to achieve the lowest delivered cost
for this clean, renewable energy resource.

“The Midwest ISO is proud to have an independent, transparent, and inclusive
planning process that is well-positioned to study and address transmission needs
in the region,” said Bear. “The RGOS is a great example of this collaborative
process in action. Key wind zones were identified to maximize the integration of
renewable energy into the region in an economically efficient manner, minimizing
the combined cost of transmission and generation while meeting the varying
energy policy goals of states in the Midwest region.”

The Midwest ISO welcomes feedback and comments from stakeholders, regulators,
and interested parties on the evolving electric transmission power system. For
