LCG, March 13, 2026--The Southwest Power Pool (SPP) announced yesterday that leaders from the participating organizations voted unanimously to proceed as planned with expanding its regional transmission organization (RTO) services into the Western Interconnection. SPP sees the decision to proceed as planned as a strong signal of confidence as SPP and its partner utilities prepare for this key milestone, which will occur overnight between March 31 and April 1.

LCG, March 6, 2026--Entergy yesterday announced approximately $5 billion in total savings for 2.3 million customers in Arkansas, Louisiana and Mississippi resulting from data center customer agreements in those states. Entergy, which completed its first data center customer agreement in 2024, projects the customer savings over the next 20 years and after the regulatory approval or acknowledgement of the public service commissions in those states.

PPL Explores Development of New Nuclear Reactor
LCG, June 14, 2007--PPL Corp. is considering the construction of a third reactor at its Susquehanna plant in northeastern Pennsylvania. PPL has notified the U.S. Nuclear Regulatory Commission (NRC) of its plans to submit an application for a combined construction and operating license (COL). Furthermore, PPL filed a request with the PJM Interconnection for preliminary transmission interconnection studies for the Susquehanna site.
The existing Susquehanna plant consists of two reactors with a combined electric generating capacity of 2,360 MW. The operating licenses for Susquehanna 1 and 2 were issued in 1982 and 1984, respectively, and the licenses for Susquehanna 1 and 2 expire in 2022 and 2024. The facility is jointly owned by PPL Susquehanna, LLC and Allegheny Electric Cooperative Inc. and is operated by PPL Susquehanna.
Filing the application for a COL with the NRC should enable PPL to meet the application submittal schedule criteria for receiving financial incentives included in the Energy Policy Act of 2005. PPL estimates the cost to proceed with the licensing phase to be approximately $70 million, which would primarily be spent by the end of next year.
PPL stated that it has not yet made a decision to move forward with construction. In addition, given the market, construction and regulatory uncertainties, along with the large capital commitment for a nuclear project, PPL would proceed with construction only in a joint venture arrangement.
PPL's interest in developing new nuclear reactors is not unique, especially given current concerns with respect to climate change and a corresponding effort to reduce the use of fossil fuels. In that nuclear reactors emit no greenhouse gases, many companies are now cautiously pursuing nuclear power, and new reactor designs are being planned as well.
Up until recently, most of the nuclear development activity was led by utilities in the Southeast, like Duke, Dominion, Southern Company, TVA, Entergy and Progress, and these companies generally planned on using either Westinghouse or GE passive nuclear designs. This year, utilities outside of the Southeast have stepped forward to pursue the development of nuclear reactors, typically through the addition of reactors at existing nuclear sites. For example, last month UniStar Nuclear notified the NRC that it has selected a site adjacent to Constellation Energy's existing Calvert Cliffs Nuclear Power Plant in Maryland for Unistar's first COL application. Unistar Nuclear's application will include AREVA's 1,600-MW, U.S. Evolutionary Power Reactor (US EPR).
Mitsubishi Heavy Industries Ltd. in March announced that it had received an order for two nuclear reactors from TXU Corp. and that it plans to submit its application to receive the reactor design certification from the NRC by the end of 2007. The order is for two US-APWRs, Mitsubishi's new pressurized water reactor. The generating capacity of each reactor is 1,700 MW. The new reactors are targeted to be built near Dallas and are scheduled to commence commercial operations between 2015 and 2020.
DTE Energy in February announced that it is preparing a license application to construct and operate a nuclear power plant at a site near the existing Fermi 2 reactor in Michigan. DTE anticipates filing its application with the NRC toward the latter part of 2008, which would meet the application submittal schedule criteria for receiving financial incentives included in the Energy Policy Act of 2005.
