Turn BESS revenue potential into bankable execution.
Forsyt connects the full commercial BESS chain. We model attainable merchant revenues and downside parameters, structure and run competitive tolling RFPs, support final contract negotiations, and benchmark operational performance against asset-specific trading replays.
Tolling & Optimization
A tolling contract is only as strong as the revenue reference behind it.
Model the BESS revenue potential
Build a bankable, asset-specific view of BESS merchant revenues, constraints, physical usage, and downside before initiating commercial discussions.
- Digital twin configuration: Power, capacity, round-trip efficiency, SoC limits, ramping profiles, grid tariffs, degradation curves, and renewable co-location.
- Full-stack modeling: 15-minute dispatch logic across day-ahead, intraday, ancillary services (FCR, aFRR), capacity mechanisms, and imbalance penalties.
- Commercial outputs: Revenue valuation pack containing yearly revenue stack, usage metrics, lifetime degradation impact, IRR, NPV, and downside sensitivities.
Tolling RFP orchestration & negotiation
Structure the commercial bidding process so optimizers, traders, and aggregators compete on standard, comparable terms, protecting project economics through contract signature.
- Process & target design: Onboard counterparties, set up a secure data room, clarify rules, and define a defensible tolling fixed-fee target memo.
- Offer normalization: Standardize and rank bids across fixed fee levels, contract tenor, product scopes, exclusion limits, and risk allocation.
- Contract close-out: Run structured negotiation rounds, push firmer economics, and audit critical clauses covering dispatch, metering, and degradation.
Independent optimizer performance benchmark
Once in operation, make battery trading accountable. Use BenchmarkPro to backcast realized market prices against physical constraints to measure captured vs. missed revenue.
- Independent trading replay: Re-run realized markets against your battery parameters to establish a neutral, defensible P&L baseline.
- Gap decomposition: Isolate performance by product, time block, active constraint, battery degradation, and operational trading execution.
- SLA support: Turn performance discussions with aggregators or optimizers into objective, evidence-based governance cadence.
Who we support
- Developers and IPPs building the commercial case for a new BESS asset, running a competitive RFP, and moving the project toward FID or transaction.
- Investors and lenders seeking to understand if tolling contracts are bankable and checking whether live operations match underwriting assumptions.
- Asset managers seeking to monitor the optimizer, verify settlement, manage underperformance, and set structured cadences for operations review.
Frequently Asked Questions
What is the BESS project worth under central and conservative revenue assumptions?
We run central and conservative dispatch simulations using our ASTRA engine, creating an asset-specific digital twin that quantifies eligible revenue streams (DA, ID, aFRR, FCR) and degradation impact.
Which tolling fixed fee is attractive, acceptable, or below the merchant value?
By analyzing merchant valuation cases against downside risk profiles (degradation and grid limits), we model the maximum commercial value your asset can capture, establishing a firm anchor for bids.
How do we compare offers with different tenor, scope, exclusions, and performance obligations?
Our RFP orchestration translates complex bids into a standardized matrix. We normalize fee structures, exclusions, performance thresholds, and degradation guarantees into a single comparative report.
Do you replace the optimizer or trader?
No. Forsyt provides the independent revenue reference, commercial process support, and performance benchmark. The chosen optimizers and traders continue to trade and dispatch the asset.
After COD, did the optimizer capture the value reasonably available in the market?
Yes, we measure this using BenchmarkPro. It performs an independent market backcast of your actual asset, highlighting exactly what was available, what was captured, and what was left on the table.
What data is needed to start BESS tolling support?
We typically require battery size, duration, location, grid constraints, expected COD, and any planned renewables hybridization. For operating assets, history of dispatch and settlement enhances benchmarking.
