Solar Electric Supply Expands Role in Madison's Bus Rapid Transit Project

Solar Electric Supply (SES) has expanded its partnership with the City of Madison, Wisconsin, bolstering the city's Bus Rapid Transit (BRT) project with additional solar energy systems. The company has now provided a total of 38 SES ADU Tiny Home Solar Systems, up from the initial 36 installed in 2023, further advancing Madison's goal of achieving net-zero energy use for its public transit infrastructure.

The expansion of SES's involvement in the project represents a significant step forward in the integration of renewable energy into urban transportation systems. Each solar system is equipped with six REC 360NP2 high-efficiency solar panels, designed to offset the energy requirements of bus stop shelters, including lighting and other electrical loads. The systems also feature Enphase IQ8 microinverters for AC grid interconnection, allowing for remote monitoring through a gateway communication system.

To meet the stringent snow loading requirements set by Madison's building department, SES utilized Ironridge racking for the solar installations, ensuring durability and reliability in the city's winter conditions. This attention to local environmental factors demonstrates the adaptability of solar solutions to diverse urban settings.

The BRT project, set to open in late 2024, will connect East Towne and West Towne malls via a 15-mile route with over 30 stations. The initiative has received substantial support, including a $110.6 million grant from the Federal Transit Administration, which will fund the route development and the purchase of 60-foot electric buses.

The expansion of solar energy use in Madison's public transportation system carries significant implications for urban sustainability and accessibility. Mayor Satya Rhodes-Conway highlighted the project's social impact, noting that approximately 66% of Madison's low-income residents and almost 41% of its people of color will be within walking distance of the BRT route upon completion. This improved access to efficient public transportation has the potential to enhance job opportunities, entertainment options, and overall community connectivity for a substantial portion of the city's population.

The collaboration between SES, Walbec Group, and Zenith Tech demonstrates the importance of partnerships in realizing large-scale sustainable infrastructure projects. Mike Gerkhardt, Electrical Project Manager with Walbec Group, praised SES for their rapid response and comprehensive support in bringing the project from concept to construction in a matter of weeks.

Metro Transit General Manager Justin Stuehrenberg's assertion that Madison's Rapid Route A will be a national 'gold standard' underscores the potential for this project to serve as a model for other cities looking to implement sustainable public transportation solutions. The integration of solar power into the BRT system not only reduces the city's carbon footprint but also sets a precedent for how urban transit can contribute to broader environmental goals.

The expansion of SES's role in Madison's BRT project reflects a growing trend in urban planning that prioritizes sustainability and renewable energy. As cities worldwide grapple with the challenges of climate change and the need for efficient public transportation, Madison's approach offers valuable insights into the potential of solar-powered transit systems. The success of this project could inspire similar initiatives in other municipalities, potentially accelerating the adoption of renewable energy in public infrastructure across the country.

As the project progresses towards its late 2024 opening, it will be closely watched by urban planners, environmentalists, and public transit authorities. The performance and impact of the solar-powered bus shelters will provide crucial data on the viability and benefits of integrating renewable energy into public transportation systems, potentially influencing future urban development and transit policies nationwide.
