PPA
HELCO
The electricity supplied by HELCO peaks when towards the beginning and end of the day when there isn't much sunlight, but still human activity that requires consumption. HELCO power is at its lowest in the middle of the day when the PPA system is generating the most energy. Although the necessary HELCO never reaches zero it averages around 80 kWs. This means the PPA is supplying the majority of the energy needed. The PPA and HELCO graphs reflect each other, as electricity is provided to the campus. On average, every time the PPA is at it's peak of 250 kWs for one hour HPA saves $67.50.
