Battery Storage Economics: Arbitrage, Degradation & LCOS
Size batteries in kW and kWh, account for round-trip losses, find the best charge and discharge hours with SMALL and LARGE, model degradation, stack arbitrage, capacity and frequency-response revenue, value a home battery with solar, and calculate LCOS, NPV and payback: 8 graded labs with illustrative prices.

About this course
A battery storage economics course that values grid and home batteries in a spreadsheet, for energy analysts, engineers, developers and homeowners weighing a battery. You size batteries by power, energy, C-rate and duration, measure round-trip efficiency, auxiliary load and the cost of losses, pick the cheapest and priciest hours of a day with SMALL and LARGE to price arbitrage, combine calendar and cycle fade into a state-of-health curve and find the end-of-life year, stack arbitrage, capacity payments and frequency response into five years of revenue, simulate a home battery with solar month by month for savings and payback, calculate the levelised cost of storage per MWh delivered and build a 15-year project cash flow with NPV and the payback year. Illustrative prices, educational only, not investment advice. The first lab is free.
