1. The Challenge:
Meritus Medical Center wanted to reduce rising energy costs, advance its sustainability initiatives, and strengthen environmental stewardship—without disrupting hospital operations. The project also required seamless integration with existing hospital infrastructure and careful coordination across multiple rooftop sections.
2. Project Drivers:
- Reduce rising energy costs
- Advance sustainability and environmental stewardship goals
- Offset a significant portion of daytime energy demand
- Support energy resiliency for a 24/7 healthcare facility
- Deliver construction and installation with zero disruption to hospital operations
- Contribute to a broader microgrid strategy designed for reliability during outages
3. Envocore’s Solution:
Envocore partnered with Meritus Medical Center and FESCO Energy to design and install a 934 kW rooftop solar photovoltaic system across multiple rooftop sections at the hospital’s main campus. The system was engineered to optimize solar production while maintaining compliance with structural, electrical, and healthcare facility requirements.
Scope included:
- Detailed solar engineering and system design
- Structural and electrical integration with existing hospital infrastructure
- Utility coordination and permitting
- Procurement of high-efficiency PV modules and inverters
- Construction management and installation
- System commissioning and performance validation
All construction activities were executed with zero disruption to critical hospital operations and patient care.
4. By the Numbers
Total Solar Installed:
- 934 kW rooftop solar PV system
Project Materials:
- 1,946 solar modules installed across multiple rooftop sections
Estimated Annual Impact:
- 1.16 million kWh annual renewable energy production
- $128K+ in annual energy savings from the rooftop solar system
Broader Microgrid Impact:
- Approximately $1.6 million in projected annual savings
- Nearly 2,000 metric tons of avoided emissions annually
- A hybrid system combining rooftop solar with CHP for improved resiliency
5. Results / Impact
The Meritus Medical Center project helps demonstrate how healthcare facilities can improve resiliency and sustainability at the same time. Envocore’s rooftop solar installation now generates more than 1.16 million kilowatt-hours of renewable energy annually, helping reduce long-term operating costs and offset a meaningful share of the hospital’s daytime load.
As part of the broader microgrid initiative, the project also supports continuous power reliability and a stronger energy strategy for mission-critical healthcare operations. Together, the solar and CHP components create a model for how hospitals can reduce emissions, manage costs, and strengthen infrastructure for the future.
6. Fun Fact
The solar energy generated by the Meritus rooftop system each year is enough to power approximately 110 average homes for a full year—a strong example of how hospitals can play a visible role in advancing renewable energy adoption in their communities.
