Pennsylvania PRESS Act (HB 501) Passes House Committee — What's Next?
The Pennsylvania Renewable Energy Standard Shift (PRESS) Act, introduced as HB 501, cleared the House Environment Committee on June 2, 2025. This is a critical legislative milestone that moves Pennsylvania closer to creating a premium GREC market for geothermal heat pump owners. For the thousands of Pennsylvania residents with geothermal systems, PRESS represents a potential new revenue stream worth thousands of dollars annually. Emergent Energy is actively monitoring the statehouse in Harrisburg to provide the most up-to-date guidance for our Keystone State clients. The momentum behind this bill is unprecedented, as lawmakers from both sides of the aisle recognize the need to modernize the state's energy portfolio. If passed, it would transform Pennsylvania from a laggard in renewable policy into one of the most attractive states for geothermal investment.
Transitioning from Tier II to Tier I
Under PRESS, geothermal heat pumps would move from Tier II to Tier I of Pennsylvania's Alternative Energy Portfolio Standards (AEPS) framework. This distinction matters enormously for credit value: Tier I credits command substantially higher prices than Tier II credits, reflecting the state's prioritization of these clean energy technologies. Currently, Tier II credits often trade for less than $1.00, making them virtually worthless for small system owners. The proposed ACP ceiling of $35 per MWh for geothermal Tier I credits would establish a price floor supported by utility compliance obligations. This shift would fundamentally change the return on investment for any commercial or residential geothermal project in the state. To see how these tiers work, visit our /how-it-works page. The reclassification is not just symbolic; it forces utilities to compete for a finite number of credits from residential systems. This competition is the primary engine that drives prices upward, ensuring that homeowners are rewarded for their contribution to the state's clean air goals.
Fixing the Current AEPS Framework
Pennsylvania's current AEPS framework classifies geothermal as Tier II, which groups it with lower-value technologies like waste coal and large-scale hydro, resulting in minimal credit prices. Moving to Tier I places geothermal alongside solar and wind — technologies that have demonstrated strong credit markets in Pennsylvania and neighboring states. This reclassification would create dedicated utility procurement obligations for geothermal credits, similar to the carve-outs that have made Maryland and Virginia's GREC programs successful. By creating a 'carve-out' or a dedicated tier, Pennsylvania ensures that utilities cannot simply fulfill their requirements with the cheapest possible credits from other states. This localized demand is what creates true market value. You can find more definitions for these terms in our /glossary. Correcting this legislative oversight has been a priority for the geothermal industry for nearly a decade. The current model failed to account for the superior efficiency of ground-source systems, essentially penalizing those who chose the most efficient technology available.
Legislative Next Steps
The bill now faces several steps: a full House vote, Senate committee review, Senate floor vote, and the Governor's signature. Based on typical Pennsylvania legislative timelines, enactment could occur as early as late 2025 or early 2026 if the bill maintains momentum. The bipartisan support shown in committee is encouraging — the vote was unanimous, suggesting broad recognition that geothermal heat pumps deserve premium credit treatment. Governor Shapiro has expressed interest in clean energy policies that promote energy independence and local job creation, which bodes well for the bill's ultimate passage. We recommend that system owners follow these developments closely and check our /states page for monthly updates on HB 501's progress. Public hearings scheduled for the fall will likely focus on the economic benefits of the bill, particularly for Pennsylvania's rural communities where geothermal is widely used. Engaging with your local representatives now can help ensure the bill stays at the top of the legislative agenda during a busy session.
Estimated Market Potential
Given that Pennsylvania is the largest PJM-territory state by population, the potential GREC market is substantial. Pennsylvania has an estimated 15,000+ installed geothermal systems, and new installations continue to grow thanks to local installers. At a $35/MWh ACP ceiling, a typical 4-ton system could generate approximately $15,000 in annual GREC revenue — a game-changing addition to the already-strong economics of geothermal heating and cooling. For commercial properties with 50-ton systems or larger, the revenue could reach six figures annually. This capital can be used to offset the original installation costs or reinvested into further building efficiency upgrades. Use our /calculator to see what your Pennsylvania system could be worth under the PRESS Act. The sheer scale of the Pennsylvania market means that utilities will have a significant need for credits, likely keeping prices close to the ACP ceiling for years. This latent demand represents one of the largest untapped pools of environmental credit wealth in the country.
Impact on the Local Geothermal Labor Market
Beyond the direct financial benefit to homeowners, the PRESS Act is designed to stimulate the local economy by creating high-paying jobs in the drilling and HVAC sectors. By making geothermal systems more affordable through annual credit revenue, the bill will drive demand for new installations across the Commonwealth. This, in turn, will allow local contractors to expand their teams and invest in new equipment specifically for ground-source projects. Pennsylvania already has a strong tradition of resource extraction and heavy machinery work, making the workforce perfectly suited for geothermal drilling. We anticipate that specialized training programs will emerge alongside this legislative shift to help meet the growing demand for skilled installers. This 'green-collar' job growth is a primary reason why the bill has received such diverse political support.
The Role of the Environmental Quality Board
Should the PRESS Act pass, the state's Environmental Quality Board (EQB) will be tasked with developing the specific regulations that govern GREC minting. This process will involve defining exactly how thermal displacement is measured and verified for both residential and commercial systems. It is expected that the EQB will lean heavily on the standards already established in Maryland, which would simplify the registration process for owners. Having standardized regional rules makes it easier for aggregators like Emergent Energy to manage portfolios across state lines, providing more efficiency and higher payouts for our clients. We will be participating in the public comment period for these regulations to represent the interests of geothermal system owners. Ensuring that the final rules are owner-friendly is a key part of our legislative advocacy.
Why Geothermal Deserves Tier I Status
The push for Tier I status is based on the superior efficiency and grid benefits of ground-source heat pumps. Unlike air-source heat pumps which struggle in Pennsylvania's cold winters, geothermal units maintain high efficiency regardless of the outdoor temperature. This reduces the strain on the grid during the coldest days of the year, preventing the need for expensive 'peaker' plants. By elevating geothermal to Tier I, the PRESS Act acknowledges that thermal energy displacement is just as valuable as renewable electricity generation. This recognition is a major victory for the geothermal industry and for climate policy across the Northeast. Our /for-installers section has more resources on the technical benefits of these systems. Furthermore, geothermal is a 24/7 resource unlike solar or wind, providing a consistent load reduction that makes the entire electrical grid more resilient. Tier I status reflects this 'always-on' reliability that air-source heat pumps simply cannot match.
