The brief
A three-building office campus was paying high demand charges every afternoon when air conditioning peaked. The goal was to cut those peaks, not just add kilowatt hours.
What we installed
Panels across all three roofs feed a 200 kWh lithium iron phosphate battery in a ventilated plant room. Control software discharges the battery when demand climbs.
- Peak demand reduced by about 35 percent
- Battery also covers emergency lighting
- Quarterly performance report included
The result
Combined energy and demand savings land at around 29,000 per year, with a projected payback of seven years.
Yearly savings
About 29,000 per year
Estimated from the first twelve months of monitoring data at current tariffs. Your own figures depend on roof, usage and tariff.
