Time Shift Renewable Energy
Challenge: Naturally variable, peak solar and wind production does not align with peak demand.
In most regions of the country, peak solar production occurs mid-morning to mid-afternoon, and wind generation more likely occurs at night. Peak demand from air conditioning occurs mid-afternoon to early evening, and heating loads occur in early morning and mid-afternoon to early evening.
Consequently, there is a significant daily lag between when solar energy production drops and demand for air conditioning peaks, and between when heating demand occurs and when wind generation commences.
Demand Energy Solution: Absorb solar or wind power during peak production and discharge energy during off-peak production.
Charge the Demand Shifter during the day during high solar, low demand hours, and overnight, during high wind production time and periods of low demand. Discharge wind and solar energy based upon seasonal demand for heat and air conditioning.
Value: Optimize the utilization of renewable source production.
Solar panels are installed on an office building or home. Demand Shifters are charged during peak solar production and discharge stored energy when needed.
