Rhode Island’s Solar Highway Initiative: Path to Sustainable Energy

Rhode Island is embarking on a groundbreaking journey to transform its highway medians into sources of renewable energy. In a state where every inch of land counts, the median strips along interstate highways and Route 146 stand out as untapped resources.

“There’s an awful lot of real estate running along our highways that could be used for the creation of renewable energy,” Representative Robert D. Phillips notes, highlighting the potential of these spaces. This visionary initiative, led by a special House commission, is set to investigate the feasibility of placing solar panels along these underutilized areas, a move that could reshape the state’s energy landscape.

A preliminary assessment by the Rhode Island Department of Transportation has identified 15 potential sites for solar arrays along the interstates, collectively spanning about 330 acres. These sites, many of which are already flat and construction-ready due to interstate building, could generate over 100 megawatts of renewable energy.

This innovative approach not only aligns with Rhode Island’s commitment to achieving net-zero emissions by 2050 but also addresses the pressing need for sustainable energy sources in a space-constrained state.

Navigating Legal and Technical Challenges

The journey towards solar highways is not without its challenges. As Joseph Brennan, an attorney from the General Assembly’s Legislative Council, explains, while state law permits solar installations on highway medians, any major development requires Federal Highway Administration approval.

This necessitates a revision of the state’s utility accommodation policy to meet federal guidelines. “I think the state has a path forward from the legal side,” Brennan says, indicating a promising yet complex road ahead.

In addition to legal hurdles, the state faces significant infrastructure challenges. Shauna Beland, director of energy programs and policy at the Office of Energy Resources, points out the difficulty of integrating new solar projects into the existing electrical grid.

With many feeder lines already at capacity, and the high cost and complexity of grid interconnection, the project demands thoughtful planning and investment. Moreover, environmental considerations, particularly the presence of wetlands in median areas, require adherence to state buffer rules for wetlands.

A Collaborative Approach for a Sustainable Future

The commission, comprising state representatives and officials from various departments, is committed to a collaborative approach, aiming to involve a diverse range of stakeholders. This includes companies experienced in solar panel installation, renewable energy academics, and representatives from the Federal Highway Administration (FHWA).

Rep. Matthew S. Dawson points out the importance of learning from other states, citing Oregon’s experience with large-scale solar roadway projects. “If you want to do something, find someone else that did it and copy what they did,” he suggests, emphasizing the value of shared knowledge in pioneering efforts.

The project’s potential extends beyond energy production to encompass economic and social benefits. By creating jobs and fostering innovation in renewable energy, Rhode Island can set a precedent for sustainable infrastructure development.

The involvement of organized labor, specifically the International Brotherhood of Electrical Workers, as highlighted by Rep. David Morales, ensures that the project benefits the broader community while aligning with the state’s economic and environmental goals.

Towards a Greener Rhode Island: A Conclusion

As Rhode Island ventures into this innovative project, it not only addresses its immediate energy needs but also takes a significant step towards a more sustainable future. The state’s initiative in converting highway medians into solar energy hubs represents a novel approach to environmental stewardship and energy independence.

With a deadline set for April 11, 2024, to submit their final report, the commission’s findings will not only determine the feasibility of this project but also shape the future of renewable energy in Rhode Island and potentially beyond.

“This is something that people want,” says Phillips, reflecting the public’s growing demand for sustainable solutions. This project, if successful, could serve as a model for other states and regions, demonstrating the untapped potential of integrating renewable energy into everyday infrastructure.
