Powerbalance2 is comprised of programmed Excel spreadsheet templates for modelling different technology mixes.
8760 hour annual wind and solar generation data from renewable energy grid modelling software such as SIREN is downloaded into the first columns and the modeled capacities are entered into the top dashboard.
The user enters technology costs into the spreadsheet and enters the desired RE and dispatachable technology power capacities for each technology into top dashboard, working from left to right.
PB calculates a step-wise reduction of power shortfalls, working left to right across columns of 8760 hours,for each energy technology in order of dispatch (lowest to highest cost), until there are no shortfalls. The user manually optimizes capacities (usually for cost) by rapid iteration until the scenario LCOE reaches its minimum.
PB displays weighted average LCOE and annual CO2 emissions for the whole scenario and the individual technologies. Also more data for each technology such as MWh and percent of total energy.
