BESS Cost Analysis
A desk-based evaluation of CAPEX, OPEX and the annual cost proforma for up to five scenarios at a specific battery energy storage project site.
Know What Your Project Will Cost to Build and Operate
The BESS Cost Analysis provides the CAPEX, OPEX and annual cost proforma of up to five scenarios for a specific battery energy storage system project site. The results give developers, owners and investors a benchmarked view of what a project will cost to build and operate.
Clients commonly use it when submitting bids into an RFP, when sensitizing around equipment options such as domestic content versus no domestic content or non-PFE MACR requirements, and when formulating a toll or capacity payment price.
Scenarios
Each scenario is one combination of the variables below. Fractal advises on the recommended scenarios for your project.
Scenario Variables
- Power (MW)
- Energy (MWh)
- Chemistry (LFP, NMC, other)
- Commercial operation date (COD)
- Number of annual cycles
- Degradation strategy: maintain usable energy capacity for a set number of years, or allow degradation
- AC vs. DC coupled, for PV plus storage projects
Scenario Outputs
CAPEX
Up-front project cost, including the battery system, balance of plant and EPC.
OPEX
Recurring annual costs to operate and maintain the project.
Annual Cost Proforma
Year-by-year costs over the project life, reflecting the selected degradation strategy.
How It Works
A focused, fixed-scope engagement with two review sessions, typically completed in seven business days.
Kickoff
Fractal and the client agree on the project site, inputs and up to five scenarios. Fractal advises on the recommended scenarios.
Preliminary Review
Fractal models CAPEX, OPEX and the annual cost proforma for each scenario and walks through preliminary results in a review webinar.
Final Report
A single report covering all scenarios, followed by a final review webinar.
