CogenS™ — Battery Energy Storage Module
Battery Energy Storage Sizing & Lifecycle Cost
Size and dispatch behind-the-meter batteries against your real tariff. LP-optimized demand-charge management, arbitrage, and solar co-optimization -- with degradation, outage resilience, and complete lifecycle cost analysis.
Why CogenS™
Battery Value Is in the Dispatch.
A battery only pays for itself if it is sized and dispatched against the real tariff and load. Rule-of-thumb sizing misses the demand peaks that matter, over- or under-builds capacity, and ignores how degradation erodes the business case over time.
CogenS™ optimizes BESS dispatch with a linear program against your actual rate structure and 8,760-hour load -- demand-charge management, arbitrage, self-consumption, and solar co-optimization -- then layers degradation, resilience, and full lifecycle economics to reveal the true value.
Capabilities
Sizing, Dispatch & Lifecycle Economics
Optimize the battery against the tariff, the load, and the years ahead.
LP Dispatch Optimization
A linear-program dispatch engine sizes and operates the battery against your tariff -- demand-charge management, time-of-use arbitrage, and self-consumption -- minimizing total energy cost across the full year.
Solar + Storage Co-Optimization
Pair the battery with on-site solar PV and co-optimize the combined system. Model self-consumption, export under NEM 2.0 / Net Billing / Buy-All-Sell-All, and the value of shifting solar into peak-price hours.
Degradation & Resilience
Cycle and calendar degradation with round-trip efficiency and PCS part-load curves. Size for grid outages with critical-load coverage, outage duration, and the cost of unserved energy.
Full Financial Analysis
NPV, IRR, payback, TCO, and LCOS with pre-loaded CAPEX/O&M, incentives, and depreciation. Building-owner and Energy-as-a-Service provider perspectives, in 75+ currencies.
How It Works
The CogenS™ BESS Workflow
A guided workflow from site load to optimized dispatch and a full report

Run & Results
Dispatch, SOC & report
An optional DER optimization pass sizes the battery (and solar) before specification; grid-outage scenarios add resilience analysis.
Signature Features
Everything You Need for Storage Feasibility
Technoeconomic Engine
Complete lifecycle cost analysis with detailed financial projections over study periods up to 50 years, building-owner and EaaS provider perspectives.
Battery & PCS Database
Real DC-block and power-conversion-system (inverter) models from major OEMs, with energy/power ratings, round-trip efficiency, and PCS part-load curves.
Dispatch Strategies
Demand-charge management, time-of-use arbitrage, and self-consumption -- solved with a linear program against your actual tariff structure for the full 8,760-hour year.
Solar Co-Optimization
Add on-site PV and co-optimize generation, storage, and grid exchange under NEM 2.0, Net Billing, or Buy-All-Sell-All metering policies.
Degradation & Resilience
Cycle + calendar degradation, round-trip efficiency, and ambient derating; size for grid outages with critical-load coverage and cost of unserved energy.
Professional Reports
Detailed reports with dispatch and state-of-charge charts, cash-flow analysis, degradation tables, and multi-vendor comparison for stakeholder presentations.
Financial Model
Energy-as-a-Service, Modeled Both Ways
A full project-finance model -- NPV, IRR, simple and discounted payback, benefit-cost ratio, and equivalent annual savings -- computed from both the building-owner (cost-of-ownership) and the Energy-as-a-Service provider (revenue) perspectives, plus the utility bill when the provider carries it. A dual-MARR solve balances each party's target return.
Energy Concession
AvailableThe provider carries the building's DER-reduced utility bill; the host pays a tariff on its own consumption -- energy $/kWh plus demand $/kW-month -- as if paying the utility, plus a service fee that recovers the provider's capital and margin.
Capacity Tolling
AvailableThe offtaker pays a capacity charge ($/kW-month) on the battery's rated power plus a throughput charge ($/kWh) on energy discharged, and supplies the charging energy itself.
Shared-Savings ESA
On the roadmapThe host pays an agreed share of measured bill savings (verified by M&V) with no upfront capital -- the provider's return is performance-linked.
On-Site PPA
On the roadmapWhen the battery is paired with on-site solar, a $/kWh power-purchase rate is charged on the delivered solar generation.
Built For You
Designed for Energy Professionals
For any professional sizing or investing in behind-the-meter storage.
Mechanical & Electrical Engineers
Size batteries and inverters against the real tariff and load profile, with LP dispatch and full lifecycle cost -- not rule-of-thumb sizing.
Facility & Energy Managers
Justify storage investments with demand-charge savings, arbitrage value, and resilience benefits modeled over the full study period.
Energy Consultants & ESCOs
Deliver defensible BESS business cases with multi-vendor comparison, degradation-aware economics, and Energy-as-a-Service deal structures.
Developers & Property Owners
De-risk storage capital by validating sizing, dispatch value, and total cost of ownership -- including resilience -- before committing.
Why It Matters
Solving the Hardest Parts of Storage Feasibility
Demand-Charge Management
Demand charges can dominate a commercial bill. CogenS™ uses LP dispatch against your true demand structure to size the battery that shaves the right peaks at the lowest lifecycle cost.
Degradation & Warranty
Batteries fade with cycles and time. CogenS™ models cycle and calendar degradation and round-trip efficiency so the economics reflect real throughput over the warranty life -- not just year one.
Resilience & Outages
Backup value is hard to quantify. CogenS™ sizes for critical-load coverage over a defined outage duration and prices the cost of unserved energy alongside the everyday bill savings.
