Save on the bill «inside», earn in the market

Peak-cut and energy management lower the bill inside the factory or building; demand response (DR) pays for what you don’t use. All three stand on the same metering.

Demand charge = billing demand × rate · billing demand is the highest 15-minute average — one high peak in winter or summer stays for a year

Peak-cut

In development

The demand charge is set by the peak demand (the highest 15-minute average), and a single high peak in winter or summer stays in the bill for the next year. As demand nears the target, the ESS discharges to shave that peak.

  • • Discharge at peaks · charge at cheap late-night rates
  • • Keep SOC in reserve for tomorrow’s peak
  • • Decides from the customer meter (15-min demand)

Energy management FEMS · BEMS

Planned

See usage by equipment and line in factories, by floor and use (HVAC · lighting · common) in buildings — and spot «where we use more than usual».

  • • Starts with metering and viewing — control after customer consent
  • • For factories, down to energy per unit of output
  • • BEMS is mandatory for new public buildings over 10,000 ㎡

Exchange demand response (DR)

Planned

Get paid to «use less» when the exchange calls in tight supply, and to «use more» when renewables are in surplus (Plus DR). Demand-response aggregators enrol customers.

  • • Reliability DR · economic DR · citizen DR · Plus DR
  • • Fits heat-pump thermal storage and customer ESS
  • • Energy metering is the basis for «how much was reduced»

One ESS, several jobs — with a fixed order of priority

Protection → grid operator orders → peak-cut and DR → the normal schedule. Battery and fire protection always comes first.
