NYC DCAS Doubles City’s Total Solar Capacity in Less Than Three Years Announces Agreement with NYPA to Expand Clean Energy Generation at NYC Public Schools and NYC Department of Environmental Protection Wastewater Resource Recovery Facilities

September 22, 2023

The City’s Solar Capacity Will Grow From 22 Megawatts to More Than 50 Megawatts, Through the DCAS/NYPA Solar Project

10 MW Solar Installation Will Be Largest Clean Energy Installation at a Wastewater Treatment Facility Anywhere in the World

NEW YORK – NYC Department of Citywide Administrative Services (DCAS) Commissioner Dawn M. Pinnock today announced that since November 2020, the City of New York has completed 10 megawatts (MW) of solar photovoltaic (PV) projects on City properties; doubling the City’s total capacity to a total of 22 MW. This achievement equates to removing over 1,500 cars from city streets per year and reducing annual greenhouse gas emissions by 8,800 metric tons of carbon dioxide equivalent (MTCO2e). 

Commissioner Pinnock, together with the New York Power Authority’s (NYPA) President and Chief Executive Officer Justin E. Driscoll, also announced that construction will begin this fall to install solar PV systems at over 60 City-owned buildings in Brooklyn and Queens. Through an agreement between the City and the state Power Authority, this work will add over 30 MW of solar PV generating capacity and up to 10 MW of large-scale battery storage to provide energy to power City operations. The 60-plus City-owned buildings will be made up of New York City public school rooftops and six Department of Environmental Protection (DEP) wastewater resource recovery facilities (WRRFs), including installations at the Wards Island WRRF, which is projected to be the largest clean energy installation at a wastewater treatment facility anywhere in the world. The addition of these clean energy installations along with other active solar installations will bring the City’s total solar capacity to 70 MW after construction is complete. By the end of 2025, DCAS will be providing the annual electricity equivalent of roughly 11,500 NYC homes. 

“As we mark Climate Week, New York City remains committed to leading on sustainability issues,” said New York City Mayor Eric Adams. “With new solar arrays being deployed to more than 60 City-owned buildings, we are rapidly scaling up our solar capacity to meet our emissions targets, and prioritizing deployment to environmental justice communities. We thank NYPA for their partnership in building a cleaner, greener future for all New Yorkers.”

“This agreement to install solar systems across our City-owned properties shows our commitment to reduce our emissions and leverage our city assets in impactful ways. Thanks to the partnership between the City and NYPA, we will double the City's total solar capacity and set an example of the powerful benefits that come from working together and not in siloes,” said First Deputy Mayor Sheena Wright.

"Together with our state partners, New York City is leading by example and taking on the challenge of transitioning to a zero-emissions energy supply with continued creativity on how to maximize our existing assets," said Deputy Mayor for Operations Meera Joshi. "Today's commitment will provide our public school students with the opportunity to participate in tangible climate action at their own schools and foster the climate leaders of tomorrow." 

“In three years, we’ve seen our solar capacity double, demonstrating our commitment to combatting climate change. The City of New York is leading by example, and we are proud of our progress in reducing carbon emissions, adding innovative technology, and installing clean energy systems," said DCAS Commissioner Dawn M. Pinnock. "We are truly excited for this new phase in our continued partnership with NYPA to expand our solar portfolio at New York City public schools. This work will also help us support DEP with building its climate infrastructure for the future. Together, we are making our city greener and more sustainable.”

“New York City Public Schools are not only the centers of our communities but the home of roughly 80% of the city’s total installed solar capacity, across over 80 sites in the five boroughs,” said Schools Chancellor David C. Banks. “This new installation will expand this important work in the years to come, and New York City Public Schools is proud to help facilitate our shift to a greener and more sustainable city.”

“As we mobilize all New Yorkers to take the steps necessary to fight climate change and save the planet, City government is leading by example by creating clean, renewable solar energy that can power more than 6,000 homes,” said NYC Chief Climate Officer and DEP Commissioner Rohit T. Aggarwala. “DEP’s wastewater resource recovery facilities already play an indispensable role in protecting the environment and now we will utilize their substantial footprint to generate clean energy for the whole city.”

“Bringing solar systems to school rooftops and other city facilities involves our communities and neighborhoods in the generation of renewable energy and encourages an understanding of urban sustainable practices that can benefit us all,” said Power Authority President and CEO Justin E. Driscoll. “With this major solar project, New York City and New York State are working together to set a nationwide example – using underutilized spaces on public properties to achieve our shared goal of transitioning to zero-emissions energy resources."

The Power Authority’s Distributed Energy Resources Advisory Services team is serving as energy advisor for the project and helped manage the competitive bidding process to ensure specifications were included. The NYPA DER team will continue to provide guidance and oversight throughout the development of the project.

The project supports New York State’s ambitious clean energy goals, specified in the Climate Leadership and Community Protection Act (CLCPA), the state’s Climate Act, which calls for 70 percent of the State’s electricity to be sourced from renewable energy by 2030.

Installation of solar projects for over 60 City-owned buildings are estimated to be carried out in 10 tranches from fall 2023 through the end of 2025, with the first project being solar rooftop PV installations at these five school buildings:
  • I.S. 49, Brooklyn, New York
  • I.S. 125 Thom J. McCann Woodside, Queens, New York
  • P.S. 175 The Lynn Gross Discovery School, Queens, New York
  • J.H.S. 185 Edward Bleeker, Queens, New York
  • I.S. 227 Louis Armstrong, Queens, New York

School Construction Authority President and CEO Nina Kubota said: “The SCA is delivering for our students, communities, and climate by including solar panels at 29 new buildings currently under construction. Our architects and engineers are thinking outside of the box finding innovative solutions, and already drastically cutting carbon emissions at schools. Moving forward, we are also committing to building all-electric new school buildings to remain at the forefront of researching and developing buildings that provide our children with the sustainable future that they so richly deserve.”

In addition to the projects atop City school buildings, there will be installations at DEP sites including the Wards Island WRRF. Upon completion in 2025, this installation will provide 10 MW of solar PV capacity and 5 MW of large-scale battery energy storage, making it the largest clean energy installation at a wastewater treatment facility anywhere in the world. The installation will build solar canopies over aeration tanks, an innovative and challenging design and construction that is unlike typical solar rooftop installations the City has completed in the past.
