FDRE & RTC Bid Optimization

Hands-on bid advisory powered by our RTC-X platform. Non-linear equity IRR maximization, connectivity-to-capacity mapping, and degradation-adjusted dispatch modeling. Team experience spans multi-GW FDRE portfolios and billions of dollars in project capex, delivering 18%+ equity IRRs.

RfP & Vendor Selection

RfP specifications designed around how your BESS will actually operate, with a contractual terms framework benchmarked against global comparatives. Bid evaluation weighs warranty evidence alongside the warranty curve, because an evaluation that treats every vendor curve as enforceable rewards the most aggressive claim.

Vendor & Contract Due Diligence

Independent due diligence across all Tier 1 BESS OEMs. Identification and negotiation of high-risk contractual clauses: warranty carve-outs, sampling rate loopholes, certification ambiguities, liquidated damages gaps. Includes cell-format bankability — emerging high-capacity formats trade real capex savings against thin field data, and the wrapper risk moves with them.

EMS & Controls Strategy

Independent EMS platform evaluation, DSM controller logic specification, and SCADA integration oversight. Independent benchmarking against the strongest platforms in the market.

Power Market Strategy

IEX DAM/RTM optimization, DSM controller logic specification, scheduling strategy, and merchant revenue modeling for operating assets. Built on observed IEX market data.

Lender & Investor Technical Advisory

Independent engineer reviews, dispatch assumption validation, degradation modeling, and bankability assessment for project finance. We speak both the technical language and the financial language.

Engagement Sprints

Scoped, time-bound engagements with defined deliverables, priced per sprint.

Bid Stage

2–3 weeks

Portfolio Connectivity & Asset Placement

Multi-criteria optimization for asset placement and connectivity allocation across complex FDRE, RTC, and hybrid portfolios. Preferred interconnection strategy, congestion and curtailment impact, capex vs evacuation trade-offs, and battery value under constrained evacuation — delivered with MESH-T, our portfolio IRR optimizer, as a scoped advisory engagement.

2–4 weeks

Bid Advisory

FDRE/RTC bid-stage support — optimal RE-BESS sizing, connectivity mapping, degradation-adjusted dispatch assumptions, and non-linear equity IRR modeling to maximize competitiveness.

Contract & Build

2–4 weeks

Technical Contract Closure Sprint

End-to-end technical review, red-flag identification, and clause-level negotiation support to get contracts signed with risk mitigated.

2–4 weeks

Design Review

SLD to layout to BOM — independent review of BESS system design, protection philosophy, thermal architecture, and fire safety.

2–3 weeks

EMS Evaluation & Selection

Independent benchmarking of EMS platforms against your commercial strategy. Feature-gap analysis, cost-value assessment, and vendor shortlisting, with no EMS vendor affiliation.

1 week

Thermal Modelling

DCIR-derived thermal model calibrated to site-specific ambient profiles. Cooling system adequacy assessment and thermal headroom analysis.

1 week

Certifications & Compliance Assessment

Gap analysis against IEC 62933-5-1/5-2, UL 9540A, IS 16270 and applicable Indian grid codes. Lab report cross-verification.

1–2 weeks

Factory Acceptance Testing

FAT protocol design and witness testing per IEC 62933-5-2 and 5-1 frameworks, including hardware-in-the-loop verification of the BMS–PCS–EMS integration before energisation. Cross-laboratory certification validation. We've caught scope gaps that would have shipped to site.

1–2 weeks

DSM Controller Logic Specification

Custom DSM logic aligned to your commercial strategy rather than the EMS vendor's default logic. Penalty avoidance, ramp-rate compliance, and scheduling accuracy.

Operate

2 weeks

Trial Run Support

On-site or remote support during trial operations. Performance benchmarking, punch-list tracking, and commissioning sign-off readiness.

2–3 weeks

Post-Commissioning Performance Audit

Independent RTE verification, capacity fade benchmarking against OEM curves, thermal performance vs design assumptions. Identifies revenue leakage before it compounds.

As needed

Dispute Resolution & Technical Expert

Independent technical expert for developer-vendor disputes. Documentation review, root cause analysis, and expert opinion grounded in hands-on commissioning experience.

1 week

BESS Augmentation Planning

When capacity drops below warranty thresholds — optimal augmentation timing, technology selection, and revenue trade-off modeling. On the contract side: integration-support obligations, config-export rights, and non-obstruction clauses that keep third-party augmentation possible. Plan early, save significantly.

Module-specific

Training

Customized modules for IPPs, OEM teams, O&M teams, trading desks, or project management. Covers BESS operations, IEX market mechanics, dispatch strategy, safety protocols — and helps OEM teams understand Indian market requirements and developer expectations.
