Learn MoreAbstract. The increasing share of variable renewable generation capacity leads to a growing interest in electricity storage technologies and a summarizing cost metric to analyze the economic viability of such electricity storage units. For conventional generation technologies, the levelized cost of electricity (LCOE) is a well-known metric.
Learn MoreWhile the utility cost, mainly comprised of thermal and electrical energy costs, is the most dominating variable cost in OpEx, ISBL and OSBL costs are the significant investment cost in CapEx. The levelized cost is also sensitive to the decommissioning cost and interest rate, but decommissioning cost depends on CapEx.
Learn MoreDiscount Rate Example (Simple) Below is a screenshot of a hypothetical investment that pays seven annual cash flows, with each payment equal to $100. In order to calculate the net present value of the investment, an analyst uses a 5% hurdle rate and calculates a value of $578.64. This compares to a non-discounted total cash flow of $700.

Learn MoreDiscount rates are a crucial factor in energy and climate modelling and associated impact assessments. Why is that? Energy efficiency measures (e.g. in buildings) typically have relatively high upfront costs, which need to be recovered by savings over longer periods. Discount rates are thus used to attribute a value to future cash flows.
