Store description excerpt

BESS Calculator is a preliminary sizing and financial modeling tool built for developers, EPC contractors, engineers, and investors working on battery energy storage system projects. It turns a rough project idea into structured technical and cost estimates in minutes, so you can move faster into your next detailed feasibility study. WHO IT'S FOR Whether you're preparing an early-stage bid, scoping a site, evaluating a hybrid opportunity, or sanity-checking assumptions before a meeting, BESS Calculator gives you a structured starting point instead of a blank spreadsheet. TECHNICAL DESIGN & CAPEX Enter your target power, discharge duration, and site conditions to get an initial DC capacity estimate, container and inverter sizing, land footprint, and a full EPC CAPEX breakdown covering battery, power conversion, balance of system, substation, transmission, and land costs. Choose between a manual oversizing margin or an engineering-calculated approach that accounts for round-trip efficiency, usable state-of-charge window, and end-of-life capacity targets. DEGRADATION & STATE OF HEALTH Model calendar and cycle-based capacity fade over your project life using configurable degradation rates for different battery chemistries. See projected end-of-life state of health, and choose an augmentation strategy: oversize on day one to guarantee output through end of life, or plan a year-by-year augmentation schedule that tracks the growing top-up capacity, land, and cost required to maintain performance. CHARGING SIMULATOR Simulate charge and discharge cycles, round-trip efficiency losses, and thermal limits to sanity-check your operating assumptions before committing them to a full design. TARIFF-BASED BIDDING & FINANCIAL PAYBACK Work through tariff, revenue, and financing assumptions to estimate payback period, internal rate of return, and net present value. Model both standalone battery storage and solar-plus-storage hybrid configurations, with support for coincident export limits, debt and equity structuring, and combined power transformer sizing. SOLAR + BESS HYBRID SUPPORT Size hybrid projects with configurable DC/AC ratios, combined transformer capacity, and shared CAPEX modeling across the solar and battery components, for consistent comparison. MULTI-REGION, MULTI-CURRENCY Switch between Indian Rupees, shown in Crores, and US Dollars, with region-aware cost bases, interconnection voltage levels, and unit conventions so the numbers match how you actually work, wherever your project is located. INDUSTRY NEWS Stay current with curated renewable energy and battery storage news across India, world, technology, and tender categories, refreshed regularly from multiple sources, right inside the app. SHAREABLE REPORTS Generate a clean, structured PDF report summarizing your inputs, technical results, CAPEX breakdown, and augmentation schedule, ready to download or share with colleagues, clients, or investors. BUILT FOR EARLY-STAGE DECISIONS, NOT FINAL
