9. Efficiency Comparison.29 BTU In Power PlantTransmission SystemHospital.06 BTU Loss.65 BTU Loss.35 BTU In1 BTU In At a Coal Fired Power Station, about 35% of the primary fuel is converted into electricity; the remainder is lost “up the stack”. An additional 6% efficiency drop occurs in transmission to the site. Overall, at the Hospital’s meter, the result is roughly a 29% efficient primary fuel conversion to useful energy. Typical Power Delivery

10. Comparison Efficiency CHP Plant 1 BTU In.25 BTU Loss.75 BTU In GRU’s South CHP Energy Center at the Shands Cancer Hospital will be 75% efficient at primary fuel conversion to useful energy. This is a 46% savings in primary energy utilization compared to the Typical Hospital Power Service Model. Hospital Cancer Hospital Power Delivery
