In Boston, ENGIE signed a 35-year energy supply and utility services agreement with Longwood Medical Energy Collaborative (LMEC), which plans and coordinates the energy services needs of Harvard Medical School and five affiliated hospitals and research institutions. 

Delivered in partnership with Axium Infrastructure, the agreement comprises an electricity microgrid and a district heating and cooling network. ENGIE’s services are enabling LMEC’s member hospitals and research centers to focus on their missions of patient care and advancements in medicine. Future sustainable energy service enhancements may include solar energy, energy storage, and facilities management. 

ENGIE’s Partnered Approach

ENGIE and its development partner Axium Infrastructure created the Longwood Energy Partnership (LEP) and are working with LMEC to align the need for safe, reliable, and resilient energy delivery with forward-looking sustainability goals. The partners also recognize, that while each LMEC entity is unique, the collaborative would be better served with a systematic, rather than a case-by-case, approach to utility infrastructure and delivery, as it would enhance efficiency and improve responsiveness. (This has been especially important during the COVID-19 pandemic.) 
The approach was jointly conceived by LMEC and LEP, and is being developed through regular meetings between ENGIE operations and maintenance personnel and the LMEC Board of Directors and Energy Steering Committee. 

The Solution

Under a 35-year agreement (through 2051), LEP will provide central plant management for LMEC’s six main medical facilities. Utility services under the agreement include a microgrid and a 112-million-square-foot district heating and cooling network that serves 74 buildings. The microgrid and district energy system have the capacity to produce 99 MW of electricity, 1,100,000 lbs/hr of steam, and 42,000 tons of chilled water.

The agreement covers operations, procurement, and risk management of power and gas systems. It also includes performance guarantees during outages or failures for 450 GWh of power, 5 bcf of natural gas, and other commodities.

Opportunities exist for future sustainability improvements through investments in solar energy, energy storage, and facilities management.

The Results

The district heating and cooling networks provide LMEC with the most efficient, reliable, and cost-effective means of providing energy while improving sustainability. They are backed by ENGIE’s risk management and performance guarantees, which give LMEC’s member healthcare and researcher institutions peace of mind as they focus their efforts on world-class patient care and advances in medicine. 

Longwood Medical and ENGIE are collaborating to further develop their long-term sustainability goals.

energy efficiency within 10 years

As a prominent higher education institution—one of the top 20 public universities in the US—The Ohio State University has long been committed to excellence.

With an ambitious goal to become an international pioneer in sustainability, Ohio State entered into a 50-year integrated solutions agreement with Ohio State Energy Partners (OSEP), a public-private partnership between ENGIE North America and Axium Infrastructure in 2017. This unique partnership not only addresses the university’s sustainability and energy operations goals, but also funds and guides academic initiatives, such as an energy innovation center and support for scholarships and internships in the realm of energy innovation.

ENGIE’s Partnered Approach

Ohio State Energy Partners is an exemplar of the partnered approach ENGIE takes with its clients. In the case of Ohio State, all the components of OSEP’s sustainable energy operations projects were developed hand-in-hand with the university. Likewise, to further the academic collaboration component of the agreement, ENGIE works closely with Ohio State’s Energy Academic Collaboration Council (EACC). Composed of students and faculty, the EACC guides OSEP’s efforts and ensures meaningful campus engagement in the advancement of the sustainability academic mission of the university.

The Solution

Leveraging the combined expertise of ENGIE, Axium Infrastructure, and Ohio State leaders, the OSEP agreement can be summarized by four areas:

Operations: As part of OSEP, ENGIE is tasked with operating the systems that power, heat, and cool Ohio State’s Columbus campus under a 50-year lease of the university’s energy assets. Through its performance guarantees, ENGIE assumes responsibility for the resiliency and reliability of these systems.

Sustainability: In collaboration with Ohio State, OSEP develops and implements energy conservation projects which contribute to the university’s ability to reduce its carbon footprint. Specifically, within the first 10 years of the partnership, OSEP has committed to improve energy efficiency by a minimum of 25% on the Columbus campus. The university reviews each capital project and approves those that are expected to provide appropriate environmental and financial benefits.

Supply: OSEP is working with Ohio State to enhance its effectiveness in the procurement process for electricity, natural gas, and other energy sources.

Academic collaboration: In addition to a $1.015 billion upfront payment to the university, OSEP will fund and carry out a $150 million commitment to support various academic, research and community interests of Ohio State. Among these projects is an Energy Advancement and Innovation Center. The center will enable Ohio State faculty members, students, alumni, ENGIE Buckeye Operations researchers, local entrepreneurs, and industry experts to work together on the next generation of smart energy systems, renewable energy, and green mobility solutions. OSEP has committed $50 million for the project, including $36.7 million in design and construction costs. In addition to this project, the partnership also supports grants, scholarships and internships at Ohio State.

The Results

Just a few years into the 50-year partnership, Ohio State has already noted improvements in sustainability, beginning with smart metering, lighting upgrades, and various facilities’ utility system upgrades.

Ohio State is benefitting from ENGIE’s significant experience and scale, which enable it to meet its energy and utility commitments.

The agreement is expected to enable Ohio State to achieve its goal of 25% energy efficiency improvement within the first 10 years of the partnership.

Various academic collaboration programs are already underway to benefit students and faculty:

  • Each year, 10 students are selected for internships with OSEP, where they work alongside ENGIE and/or Axium team members to support, design and develop capital projects, to drive campus efficiency.
  • Students can participate in a range of events like the Smart CampusE Challenge, a venture capitalist-style student sustainability competition. The winning teams receive funding and expert guidance to implement their project on campus.
  • Those living on campus can also take part in Residence Hall Energy Competitions, where students compete against other dorms to conserve the most amount of energy.
  • OSEP has also co-sponsored West Fest, an interactive community event that showcases how Ohio State researchers and community partners are working to protect the environment, improve natural resource use, and enhance people’s daily lives.

The Energy and Advancement Innovation Center—currently under development—will be a place where collaborators work together on the next generation of smart energy systems, renewable energy, and green mobility solutions. By providing the support and resources necessary to become commercially successful, the center will help promising projects to find a route to market.

students access enhanced STEAM activities


Piggy Bank


in energy savings

Located in the San Francisco Bay Area, Hayward Unified School District (HUSD) serves over 20,000 students from preschool to adult school across 33 District campuses.

Starting in 2018, District leadership began exploring opportunities to make various improvements to its facilities and implement sustainable energy solutions to reduce utility spending. At the same time, District leaders saw renewable energy upgrades as a unique opportunity to provide meaningful connections to science, technology, engineering, art, and math (STEAM) concepts for students. To accomplish these objectives, HUSD partnered with ENGIE.

ENGIE’s Partnered Approach

ENGIE is committed to building three dimensions of impact for every customer’s future. Looking beyond simple financial savings, ENGIE combined environmental, fiscal and educational sustainability to create a platform for hands-on learning, teacher training and community awareness. ENGIE’s dedicated team of local energy experts worked closely with District staff to design and develop the program to be specifically customized for their energy needs. In conjunction, ENGIE’s Community Impact team collaborated with District principals and teachers to create hands-on STEAM activities that turn the District into a living laboratory, using the modernizations as a platform for hands-on learning and STEAM career exposure.

Hayward Unified School District

The Solution

ENGIE partnered with the District to upgrade all 33 District sites with infrastructure improvements, solar shade structures, roof and ground-mount arrays. The implementation includes 5.3 MW of solar PV, 360 kW/720 kWh of battery storage and 38 electric vehicle (EV) chargers, creating a robust District-wide renewable energy profile.

ENGIE collaborated with sister company EVBox to procure the 38 EV stations, which were set up across 22 District sites and offer a total of 76 charging ports. HUSD was able to take advantage of grants for EV charging stations from the Bay Area Air Quality Management District.

The Results

The District is projected to see $65MM in General Fund savings over the life of the program. The new solar installations are expected to generate 90% of the District’s needs, through the production of 8,100,000 kWh in the first year—the equivalent to powering 650 homes for a year. This clean, on-site renewable power reduces costs and protects against future electricity rate increases.

In addition, the battery storage systems, funded in part by California’s Self-Generation Incentive Program (SGIP), are connected to the District’s solar arrays to reduce peak demand charges, optimize facility energy usage, and maximize utility savings. The District can access real-time energy data via the user-friendly ENGIE Utilityvision™ dashboard.

HUSD schools are also becoming a community hub for EV charging. As more EVs hit the road and drivers are looking for a public place to charge them, District staff, students, and parents will be able to charge vehicles while class is in session. The new charging stations contribute to meeting California’s goal of putting 5 million zero-emissions vehicles on the roads by 2030 and installing a total of 250,000 EV charging stations by 2025. Overall, the program is expected to provide environmental benefits equivalent to removing 1,153 cars from the road annually.

The project has also provided an opportunity to enhance students’ understanding of climate issues—and expose them to STEAM careers—through direct engagement with the science behind the sustainability project. ENGIE’s Community Impact team partnered with principals and teachers across the District to design, and support the implementation of, hands-on STEAM initiatives, such as the following :

  •  Science Fair: ENGIE engineers and energy professionals served as judges for the 2018 and 2019 District Science Fair and Family Technology Awareness Day, in addition to hosting a booth at the event with hands-on STEAM activities.
  • 6th Grade Curriculum Development: In the summer of 2018, ENGIE’s Education team co- developed a 12-lesson Next Generation Science Standards (NGSS)-aligned Climate Change unit for the 6th grade, including materials kits for hands-on activities, and interactive professional development (PD) sessions for teachers.
  •  Preschool STEAM Program: ENGIE will provide STEAM activities and materials for ten classrooms and an accompanying PD session for the District’s youngest learners in the Hayward USD preschool program.
  • Living Labs: Real-time generation data from the solar panels are available to all District students and teachers via a web dashboard.
  •  High School Student Summer Internships: ENGIE is offering eight-week internships for Hayward USD high school students who are interested in pursuing careers in engineering. Students will work with ENGIE engineering mentors to gain experience on the construction site of a large-scale renewable energy project.
  • Three New STEAM Buildings: District educators and ENGIE’s Education team are currently developing programming for new STEAM buildings on the middle school campuses.
With critical support from our broad ‘Made in Hayward’ community—our Hayward families, local partners, and our Board—we have been able to transform our schools with dynamic infrastructure improvements that enhance the learning environment and put money back into our General Fund for other classroom needs. With meaningful alignment with STEAM opportunities tied to our program, these upgrades produce positive dividends for our students in multiple ways.”
