For finance, commercial and investment people
Add results from the technical tools as measures, then see the combined capex, saving, payback, NPV and IRR, the cost per kWh saved and a cost curve. Save the project as a file.
A 1 MWp rooftop plant financed with senior debt: generation, PPA revenue, tax losses and the cash-flow waterfall, with returns, DSCR, LCOE and sensitivity.
The after-tax business case for an efficiency investment, with and without the section 12L allowance: NPV, IRR, payback and sensitivity.
The constant price per kWh that recovers capex and O&M over the life, in real and nominal terms, with a capex/O&M split.
Compare buying a rooftop plant, paying per kWh under a PPA, and a rent-to-own lease on the present value of cost, with an optional section 12B tax view.
How much senior debt a cash flow supports at a target DSCR, with a sculpted repayment and with a level annuity, capped by maximum gearing.
Escalate the tariff, discount the savings and see what saving one kWh a year is worth today: the most you can spend for a saving to break even.
For engineers and facility managers: Size the fix and see what it saves: notified maximum demand, power-factor correction, load factor and time-of-use, solar yield, battery peak shaving and variable-speed drives. Inputs are the numbers on an electricity bill or a nameplate. Technical tools
