Make your assumptions
work harder.
Change the inputs to explore annual electricity demand, renewable capacity and an indicative battery requirement. Every calculation stays visible.
Your illustrative results
The method, in plain sight.
Electricity demand
Average MW = peak MW × average load fraction.
Annual MWh = average MW × operating hours.
Renewable capacity
MW = target annual MWh ÷ (8,760 × capacity factor). Annual matching is not hourly supply or renewable certification.
Battery sizing
Delivered MWh = average MW × covered fraction × duration.
Nameplate MWh = delivered MWh ÷ usable fraction ÷ discharge efficiency.
Energy-only cost
Annual MWh × your price per MWh. Excludes demand charges, network costs, taxes, financing and capital expenditure.
No hourly dispatch, weather model, outage simulation, connection study, cost optimisation or resilience guarantee is included. Battery power is based on average covered load, so peak-critical-load sizing may be higher. A zero storage duration gives zero indicative storage power and energy.
