CARBON REDUCTION AND ENERGY GENERATION
Heating power accounts for approximately 80-90% of the hospital’s gas usage. The original hospital design includes six gas-fired boilers, each with a 3 MW capacity, supporting heating hot water (HHW) and DHW via heat exchangers and loops.
hydrogen Proton Exchange Membrane Fuel Cell (PEMFC) technology. Initially, we retained the diesel generators to meet traditional demands while deploying a 9 MVA PEMFC power plant. As hydrogen technology becomes more available, the diesel generators can be progressively replaced by additional PEMFC modules, eventually achieving a zero-carbon backup solution.
Conclusion Overall, after electrifying fossil fuel-dependent loads and upgrading the infrastructure to support EV chargers and solar PV generation, the total grid capacity demand of the electrified hospital has increased from the original 16 MVA to 32 MVA (a factor of 2), considering the grid demand reduction achieved via solar PV and the BESS. Without these considerations, the increase is from 16 MVA to 36 MVA (a factor of 2.25). Our all-electric hospital architecture demonstrates a
practical approach to decarbonisation in healthcare facilities. This transition supports healthcare facilities in meeting their Net Zero goals while maintaining reliability and cost-effectiveness. As we continue this journey, engagement with grid authorities and leveraging green
technologies will be crucial in addressing the increased demand for electricity and ensuring sustainable healthcare infrastructure. The rise of the all-electric hospital is no longer a distant
aspiration, but an achievable reality, with the potential to deliver profound benefits. Arriving at that reality requires careful planning, capital investment, specialised expertise, alignment, and collaboration across multi-disciplinary stakeholders within the estate. Establishing a network of external experts and advisors is equally important to your pursuit. With specialised expertise in the healthcare sector, a best-in-class portfolio of software, and infrastructure solutions for all-electric hospitals, Schneider Electric is the proud partner of more than 6,500 healthcare sites worldwide. At Schneider Electric, we believe nothing should hold your healthcare facility behind. Join us today as we journey towards the healthcare facility ahead of its time.
