Energy Storage Modeling & Analytics

Solar+Storage

Energy Storage modeling & value analytics Providing statistically-based data science techniques to optimize battery system size

Battery system analytics

Access to GE Energy Consulting grid studies & detailed Li-ion battery efficiency and lifetime models in Predix

Analyzes solar power purchase agreement (PPA) and sizes battery to optimize solar payments

Links GE controls to prioritize battery charge and discharge times using hourly cost analysis

Accepts inputs of each customer’s unique load profile or PV simulation to customize project analysis

Identify possible additional revenue streams from ancillary services

Final value analytics package

Access to GE’s data science capabilities

Customized project sizing & alternate recommendations (e.g. ancillary services)

Sensitivity analysis & customization can be run in real-time to generate alternative project outputs

Full financial analysis & support for each project and use case (e.g. IRR, NPV, cash flow stream)

Example: Coupling GE Energy Storage & Solar

13

Result & recommendation

Result: 1.8MW/9MWh deal has the best financial return

Consideration: Ability to capture additional revenue streams from frequency response, VAR support or spinning reserve

Ran 15 different scenarios for size of project vs. expected return

Customer problem• Did not have 1 minute solar production estimates necessary to size battery for firming• Did not have the ability to simulate battery degrade and efficiency over 20 year project to estimate revenue, CapEx & OpEx

Desired outcome• Shift solar energy output and provide firm power coincident with utility peak demand to maximize PPA value proposition

+

Used GE data science to simulate 1 minute PV production for 20 year scopeCreated multiple scenarios with customer for use of combined PV + storage plant and analyzed each scenario for optimal battery size

Calculated revenue stream for each potential scenario to optimize system size by NPV & IRR

Modeling process

So … how can GE help with your energy storage needs ?

• Full EPC or EEP only (engineered equipment package, with installation by others)

• Full system commissioning by GE in either case

• Performance Guarantees• 10 or 20 years

• Covers: Availability, Capacity, AC/AC Efficiency

• Custom metrics can be guaranteed; i.e. PJM Performance Score

• Project Finance, including generation asset (solar, wind, or gas turbine)

• Detailed engineering, modeling and studies to optimize BESS system design & performance
