Overview of Data Center Growth
As data center development surges across the United States, New Hampshire legislators and regulators are evaluating the implications for the state's aging electric grid. Craig McGahey, a data center developer, highlighted the increasing demand driven by artificial intelligence and competition among major cloud computing companies like Google, Meta, and OpenAI during the 2025 New Hampshire Energy Summit. Despite the national boom, New Hampshire currently hosts only ten small-scale data centers, placing it in the bottom fifth of states for data center presence.
Legislative Perspectives on Data Centers
Some New Hampshire lawmakers advocate for creating a favorable regulatory environment to attract data centers, citing potential benefits such as property tax revenue and job creation. Rep. Doug Thomas, vice chair of the House Science, Technology, and Energy Committee, emphasized the need to demonstrate interest in attracting businesses. However, skepticism exists regarding the actual job creation potential, with Rep. Thomas Cormen noting that data center employment does not scale proportionally with size. Concerns also arise about the environmental impact of data centers, particularly regarding water usage and power supply.
Energy Supply Challenges
The New Hampshire Department of Energy is exploring options to enhance electricity generation, including small modular reactors (SMRs) and microgrids. Director of Energy Innovation Thomas Barrasso expressed optimism about the potential for SMRs to support data centers, although critics argue that this technology is still in development and may not be a timely solution. Alternative energy sources, such as renewable energy and battery storage, were suggested as more immediate options by Dan Weeks of ReVision Energy.
Environmental and Regulatory Concerns
Legislators like Sen. David Watters have raised alarms about the environmental implications of data centers, particularly their energy consumption and water usage. The cooling processes of some data centers can adversely affect local water bodies, raising concerns about ecological impacts. Additionally, uncertainty about how data centers would be powered poses challenges, as reliance on the grid could increase electricity costs for residents.
Future Considerations and Legislative Actions
The New Hampshire Legislature has taken initial steps toward localized power generation, including House Bill 672, which allows off-grid generators to sell power directly. However, the state faces significant hurdles in attracting large-scale data center development due to its aging grid and power shortages. McGahey noted that developers are seeking quicker-to-deploy energy solutions, such as natural gas plants and battery storage, to meet the rising demand for data centers.
Conclusion
The debate surrounding data center development in New Hampshire reflects a complex interplay of economic opportunity, environmental concerns, and energy supply challenges. As lawmakers and regulators continue to assess the potential impacts, the future of data centers in the state remains uncertain, with discussions ongoing about how to balance growth with sustainability and community needs.
