Harrisburg Data Center Uses Rooftop Solar for 40% of Energy

Alerify CEO defines the physical reality of the cloud

A data hosting facility near Harrisburg uses rooftop solar to supply roughly 40% of its energy, according to a report from abc27 (WHTM).

The facility, operated by Alerify, houses rows of metal cages, wires, and blinking lights rather than the abstract concept the term “cloud” often suggests. Andy Kochanowski, the founder and CEO of Alerify, provided a tour of the site to show the industrial scale required to maintain digital services, Tech Insider reported.

“So when you hear the word cloud, this is what we call the cloud,” Kochanowski said during the tour.

The massive energy requirements of digital storage

Electricity represents the primary operating expense for the Alerify facility. While Kochanowski did not disclose the specific dollar amount of the monthly bill, he identified power as the company’s number one expense.

The facility utilizes large air-conditioning systems to cool computer equipment and regulate humidity. This cooling is critical because servers convert nearly all consumed electricity into heat. If the air becomes too dry, static discharge becomes a risk; if it is too damp, corrosion can damage the hardware.

Kochanowski distinguished his operation from the newer wave of artificial intelligence campuses. He noted that AI centers use exponentially more energy than the conventional CPU-based hosting provided by Alerify.

Harrisburg facility maintains four distinct backup layers

To prevent service interruptions, the Harrisburg facility maintains four distinct backup layers. These systems are designed so that no single failure takes a customer offline.

  • Power and Cooling: The facility uses uninterruptible power supplies (UPS) and batteries to bridge the gap between a utility outage and the startup of generators. Spare air-conditioning units are kept on hand to cover cooling failures.
  • Internet Connectivity: Redundant network paths are used to route traffic around fiber cuts or carrier outages.
  • Data Integrity: Copies of customer data are maintained to protect against disk or server failures.

Rooftop solar hedges against rising energy costs

The use of rooftop solar at the Alerify site provides a meaningful hedge against rising energy costs, though it operates on a different scale than the massive power needs of the region. While the rooftop array covers about 40% of the facility’s energy, it cannot match the gigawatt-scale requirements of upcoming AI campuses.

The scale of energy demand in the region is shifting rapidly. According to data from the Pennsylvania Public Utility Commission, the state’s electricity demand in 2025 sat at approximately 150 terawatt-hours. However, high-load scenarios for the PJM grid suggest that data centers could add more than 200 terawatt-hours of new load between 2029 and 2030.

Pennsylvania electricity demand (2025) About 150 TWh Pennsylvania PUC
PJM data center load addition (2029–2030 high-load) More than 200 TWh Pennsylvania PUC
PJM summer peak demand (2025 actual) 162,400 MW Pennsylvania PUC
PJM summer peak demand (2030 forecast) 183,009 MW Pennsylvania PUC

Solar energy is increasingly part of the state’s energy mix. Reuters reported in February 2026 that solar made up 7.2 gigawatts of the 14.7 gigawatts of Pennsylvania power projects in PJM’s active queue as of May 2025.

Data center expansion triggers local scrutiny and legal challenges

As data centers expand, they are moving from server closets to massive regional campuses, triggering intense local scrutiny. In Swatara Township, a data center campus is currently under construction on the site of the former Dauphin Highlands Golf Course, WGAL reported.

Politics in Harrisburg is also changing. WGAL reported on November 6, 2026, that recent election results could reshape how Pennsylvania regulates and taxes these facilities when the new legislative session begins in January.

“The cloud isn’t really in the cloud—it’s in data centers.”

State Senator Tracy Pennycuick, majority chair of the Senate Communications and Technology Committee, made this observation to the Harrisburg Regional Chamber in August 2026.

The tension between traditional hosting providers and massive AI-driven campuses defines the current era of Pennsylvania’s tech infrastructure. While a local provider like Alerify manages cooling and cages to provide “peace of mind,” the larger campuses are engaging in a massive scramble for power, often seeking onsite generation to bypass grid constraints.

Will the incoming legislative session prioritize the tax revenue from these massive campuses, or will it implement stricter regulations to protect the state’s electricity supply for residents?
