It is a somber sight to see towering smokestacks fall. They serve as monuments to a past era, symbols of industry and progress – until they are no longer needed. Last month, the demolition of the Homer City Generating Plant in Indiana County marked the end of a once mighty, coal-fired power station.
The plant’s Unit 3 chimney, once the tallest in the United States at 1,217 feet, could be seen from Greensburg to Ebensburg. Now, it is just dust and memory. The Homer City Generating Plant was a 2.
0 gigawatt coal-fired facility that began operations in 1969, employing 124 people at its peak. It was once the largest coal-fired power plant in Pennsylvania and ranked among the 25 largest power plants in the United States. For decades, it contributed significantly to the region’s economy and energy infrastructure.
Like many coal-fired plants, Homer City struggled under economic and regulatory pressures. Originally built by the Pennsylvania Electric Co., its ownership shifted to private equity firms, with Knighthead Capital Management holding a 75% stake and Golden Tree Asset Management owning about 12%.
The plant endured two bankruptcies, the latest in 2017, before ultimately succumbing to the growing push to eliminate coal-fired power generation. Yet, as one chapter ends, another begins. The site is now poised for an ambitious redevelopment – a 4.
5-gigawatt natural gas-fired power plant that will support a state-of-the-art artificial intelligence data center and high performance computing. With an initial $10 billion investment in power generation and site preparation, followed by additional billions for the data center, this project represents a historic economic transformation for the region. The financing will be largely private, led by Knighthead, with minimal public funding – only a $5 million state grant for a gas line extension so far.
In January, Gov. Josh Shapiro proposed a tax incentive plan for projects supplying electricity to the grids and utilizing hydrogen. The proposed tax credits could amount to as much as $100 million annually for newer plants.
So far, this is only a proposal, but it is possible the project may, eventually, receive some public funding. The scope of this development is staggering. Over the five-year construction period, an estimated 10,000 construction jobs will be created with 1,000 permanent positions, primarily at the data center.
This project is projected to be the largest single private investment in Pennsylvania’s history, surpassing even the Shell ethane cracker plant in Monaca, which ultimately cost $14 billion. Though specifics on the data center remain undisclosed, its potential is immense. Data centers are typically measured by power consumption, square footage, and computing capacity.
Given the planned 3,200-acre campus, it is likely to house cutting-edge AI data handling and high- performance computing. Estimates of power consumption for data and computing are in the range of 125 megawatts. For perspective, the largest data center in the U.
S., the Citadel in Tahoe Reno, Nev., requires approximately 130 megawatts.
The NSA’s facility in Bluffdale, Utah, consumes around 65 megawatts. Homer City’s data center could easily be in this league, if not larger. Powering this operation will be the largest gas-fired power plant in the U.
S., generating 4.5 gigawatts.
Most of this energy will be supplied to the PJM Interconnection and New York Independent System Operator power grids, serving multiple states, while a portion will be dedicated to the data center. To put it in perspective, 4.5 gigawatts could power three million homes – nearly twice the entire consumption of Pittsburgh.
The plant will be fueled by Pennsylvania’s vast Marcellus and Utica shale reserves. Its seven GE turbines will require approximately 530 million cubic feet of natural gas per day – the output of about 70 dedicated gas wells. Some will ask why renewable energy is not being considered.
The reality is that solar and wind alternatives would require vast amounts of land and infrastructure. Due to Pennsylvania’s moderate solar irradiance, solar panel efficiency is around 15%, meaning 75 million panels and 230 square miles of land would be needed to match 4.5 gigawatts of production.
Wind power, with a 30% efficiency factor, would require 5,000 turbines spread across 1,875 square miles – twice the size of Washington County. While these technologies are crucial to the broader energy mix, they are not yet practical for a development of this scale. As the dust settles at Homer City, what emerges is not just a replacement but a reinvention – an economic powerhouse poised to redefine Pennsylvania’s industrial landscape.
With cleaner energy, cutting-edge technology, and substantial job creation, this transition represents the future of energy and economic growth in the region. For those who watched the smokestacks fall with heavy hearts, the promise of what’s to come should be a source of great hope. Dave Ball is the former chair of the Washington County Republican Party.
