MISO to Re-File Entergy Cost Allocation Proposal According to FERC Guidance

CARMEL, Ind., Sept. 27, 2011 /PRNewswire/ — In June 2011, MISO asked the
Federal Energy Regulatory Commission (FERC) to waive, during a transition
period, tariff provisions related to the cost allocation of network upgrades
associated with Multi-Value Projects in order to establish a smooth and fair
transition for integrating Entergy operating companies into MISO.

Today, FERC advised MISO that submission of modified tariff sheets is the
appropriate vehicle for seeking this change. FERC did not speak to the merits of
the waiver request, in fact, noting that “(w)e make no findings here as to the
nature or the duration of any transition arrangements that may be appropriate to
integrate Entergy into MISO.”

Based on this FERC guidance, MISO will work with its stakeholders to quickly
craft the appropriate changes to its tariff that will accomplish the same
objectives sought in the waiver.

Aldie Warnock, MISO’s government and regulatory affairs vice president, issued
the following statement:

“Our objective is simple. As Entergy transitions into the MISO market, we want
to make sure that both existing customers and new ones only pay for projects
that benefit them. That’s what we sought to do with this waiver, and we will
continue to pursue that objective under the direction the FERC has provided.

“Our focus is on improving reliability and delivering power at the lowest
possible cost. We consistently do that today for our members and we look forward
to doing that for Entergy and its customers as well.”
