- | Given a system at 15% SOC that has set the battery costs to 0.06 €/kWh, energy prices right now (11.00) set at € 0.29 and becoming € 0.40 this evening. Why would it feed into the grid already and not wait until the prices are higher? | ||
- | The battery cost is € 0.06 per kWh. This means that for a cycle of battery usage to be useful (financially beneficial) the price difference should be at least € 0.12 cents per kWh (€ 0.06 for charging, and € 0.06 for discharging). € 0.40 - € 0.29 is € 0.11 which is below that, hence Dynamic ESS does not want to use the battery for this task, instead it is offloading the excess to the grid. | ||
