Why This Site

A battery energy storage project needs what any new energy asset needs: land, a connection to the grid, and transmission to move the power. Assembling them from scratch takes years. The EEI/Joppa plant site already has all three.
The EEI/Joppa Power Plant, owned by Electric Energy Inc., occupied this property in Massac County for decades. The site carries established transmission equipment connecting it to the regional grid.
The plant retired in 2022. Vistra announced the accelerated closure in April 2021 under a settlement that moved the retirement date forward.
EEI/Joppa is already playing a role in a renewed and strengthened grid. Pulaski Solar, a 405-megawatt facility completed in neighboring Pulaski County, reaches the grid through an eight-mile line that connects at this plant site. The interconnection built for coal generation is now delivering zero-carbon electricity to Illinois.

Project scope changes as development work proceeds, and no decision to construct has been made. Any project at the EEI/Joppa site would depend on market conditions, permitting, interconnection and other approvals.

What a Project Here Would Mean

Building a project at the EEI/Joppa site would deliver a one-time economic stimulus to Massac County — capital investment at the site, wages for local trades, and spending through the local supply chain.
The figures below are what that was modeled to produce.

Local earnings$5.9MEarnings for local workers during construction.
Local economic output$10.2MAdded economic activity in the county during construction.
Economic impact figures were modeled for Vistra by Dr. David G. Loomis, Strategic Economic Research, LLC.

This Has Been Done Four Times in Illinois

EEI/Joppa is a proposal. The approach behind it is not.
Baldwin68 MW of solar with energy storage in Randolph County, operating.
Newton52 MW of solar with energy storage in Jasper County, operating.
Coffeen44 MW of solar with energy storage in Montgomery County, operating.
Pulaski405 MW of solar in Pulaski County, connected through this site.
Three of the four sit on existing plant property, using the same combination of land, interconnection and transmission that the EEI/Joppa site has. The fourth, Pulaski Solar, was built on leased farmland and connects to the grid here.

Questions About the EEI/Joppa Site

No. A utility-scale battery energy storage project has been under development for the site, but no decision to construct has been made. Energy projects of this size take years of diligence, engineering, permitting and interconnection work before anyone breaks ground.

No, but it connects here. Pulaski Solar is a 405-megawatt facility built on leased farmland in neighboring Pulaski County. An eight-mile transmission line carries its output to the retired EEI/Joppa plant site, where it reaches the regional grid through the interconnection the coal plant used.

Because the hardest parts are already there. New energy assets need land, a connection to the grid and transmission to carry the power away, and assembling those three from scratch can take the better part of a decade. The EEI/Joppa plant site has all three in place already.

Yes, four times. Baldwin, Newton and Coffeen pair utility-scale solar with energy storage on existing plant property and are operating today. Pulaski Solar, a 405 MW facility, reached commercial operation ahead of schedule.

Modeling for a redevelopment project at the EEI/Joppa site estimated 101 jobs supported in Massac County during construction, $5.9 million in earnings for local workers and $10.2 million in added local economic output.

The EEI/Joppa plant closure page carries the community briefings, resident letters and community updates published during the retirement, including the April 2022 community update.

Plant Closure and Community Updates

Materials published for the community during the plant’s retirement remain available, including resident letters, community briefings and the April 2022 and June 2022 community updates.
