GenCalc - tool for matching half-hourly power demand with effective supply. Evaluates economic, environmental and energy aspects of each supply. User inputs data such as demand profile, electricity tariff, plant operating times and an appraisal is then presented in the form of a graphical performance view.

DemCalc - tool for estimating demand-side energy reductions resulting from energy efficiciency options. Recomended to be used in conjunction with a dynamic thermal simulation package such as ESP-r (see esru) where transient effects need to be accounted for.

Financiator_solo (included within GenCalc) - tool for evaluating the long term economics of funding energy effective technologies. User inputs values for discount factor, inflation, borrowing rate & VAT. Tool presents results in terms of cash flows over 25 years and a cumulative NPV graph over this period.
