STANDALONE STORAGE OR HYBRID SYSTEM ANALYSIS
Fractal Model is a technoeconomic energy storage modeling package used project development, due diligence and RFP evaluation. The Fractal Model provides investment grade analysis by simulating performance, degradation, warranty, costs and revenues to optimize the economics of your energy storage and hybrid projects. The Fractal Model platform uses Fractal’s Cloud Based Optimizer and seamlessly integrates with Fractal’s MS Excel based Financial Models and Dashboards.
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
