STANDALONE STORAGE OR HYBRID SYSTEM ANALYSIS
The Fractal Model™ is a powerful technoeconomic energy storage and hybrid system modeling tool that provides investment grade analysis while simulating performance, degradation, warranty, costs and revenue to optimize the economics of your project. The Fractal Model platform is a MS Excel package with an additional JavaScript engine through a Microsoft 365 Add-In.
ONE TOOL FOR YOUR ENTIRE BESS LIFECYCLE
The Fractal Model provides project visibility and optimal outcomes across the entire project lifecycle.
-
PROJECT DEVELOPMENT
Use the Fractal Model for pre-construction design and analysis or to determine bids for RFPs. Maximize long-term return for merchant and/or contracted business models. Optimize sizing and off-take structure.
-
RFP EVALUATION
Use the Fractal Model to evaluate the impacts of CAPEX and OPEX. Quantify costs associated with auxiliary load, monitoring, degradation, warranty and performance guarantees, maintenance, etc. Compare bids for lowest total cost of ownership.
-
DUE DILIGENCE / M&A
Use the Fractal Model for pre-construction design and analysis or to determine bids for RFPs. Maximize long-term return for merchant and/or contracted business models. Optimize sizing and off-take structure.
-
DISPATCH OPTIMIZATION
Use the Fractal Model to evaluate the physical and financial impacts of a modified or new dispatch strategy for your operational BESS. Import pricing forecasts and perform sub-hourly revenue optimization for merchant participation.
VERSION 23.12 JUST RELEASED
Quarterly update Version 23.12 (released in December 2023) included the following new features:
FMV in Tax Equity Model
Use the new input for asset basis step up to a Fair Market Value for tax equity models.
Advanced Dispatch Optimization
New features to incorporate market restrictions, market dilution and risk adjusted trading rules.
Historical Benchmarks (ERCOT)
Get 4 years of historical energy and ancillary prices to quickly benchmark past performance.
FEATURES
The Fractal Model features include:
- Iterative technical design and financial analysis
- Optimization of project revenues and costs
- Standalone BESS, PV+S (AC or DC), W+S, PV + W + S, PV + PV + S
