RTC-X Sizing &
Simulation Platform

FDRE / RTC Sizing

Optimal RE-to-BESS ratios, storage duration, and connectivity-to-capacity mapping, solved as a non-linear equity IRR maximization across the project life. Technology-agnostic: lithium-ion, flow batteries, pumped hydro, and emerging chemistries, each with its own cost trajectory.

BESS Placement Decision

Where to place storage across your portfolio for maximum contractual compliance and merchant upside. Site-specific ambient, grid, and curtailment inputs.

Augmentation Strategy

When to augment, how much, and which chemistry — modeled against degradation trajectories, warranty thresholds, and revenue trade-offs over the project life.

Resource Risk — Monte Carlo

Monte Carlo simulation over historical resource years delivers the full EIRR distribution and the minimum-DSCR distribution — a P50 and P90 you can defend, with debt-shortfall scenarios flagged before you commit to the tariff.

Price Intelligence

96-block DAM forecasts with confidence bands. RTM spike flags. Market selection per block. Delivered before the DAM deadline, every day.

Hybrid Optimizer

Co-optimizes solar + wind + BESS as one system. PPA obligations as hard constraints. Merchant upside in remaining capacity. Intraday re-dispatch.

Battery Digital Twin

OEM warranty envelope mathematically enforced — SoC, C-rates, thermal limits, degradation. The optimizer cannot violate these constraints.

Risk Modes

Three operating modes: Conservative, Moderate, Aggressive. A ₹50K arbitrage that costs ₹2L in degradation gets skipped automatically.

Availability Risk Exposure

97% availability sounds standard — until you read the fine print. How is it calculated? Are planned outages excluded? Is it measured at the container, system, or POI level? Does the LTSA tie availability guarantees to O&M fee escalation — or does coverage weaken as the asset ages? A 3% gap in definition can mean weeks of uncompensated downtime.

SAT — Are You Testing What Matters?

Are you measuring usable energy at the BESS meter or at the DC terminal? Is RTE measured AC-AC or DC-DC? Is power tested at 51°C ambient or lab conditions? Does your SAT cover fire suppression system activation, FACP response, and chiller performance under peak ambient — or just the battery? The wrong measurement point or missing test can lock in years of underperformance you can't claim against.

FAT — Evidence, Not Declarations

Repairing at site is a mess — logistically, commercially, and contractually. FAT is where you catch defects before they become site-level problems: DCIR variance, capacity shortfalls, cell age, thermal non-uniformity, BMS communication faults, and chiller/FACP integration gaps. And vendor declarations are not bankable — lot-wise capacity and DCIR distributions as raw data, batch traceability from cell to container, and cell-age limits at dispatch are. Evidence packages belong at FAT, not at warranty-claim time.

Warranty Enforceability & the PBG Cliff

A 20-year warranty on the cover page is a commercial wrapper — what matters is whether it pays out. What backs your recourse when the performance bank guarantee steps down? On many contracts, post-year-five recovery collapses to the annual LTSA fee — a fraction of the exposure. Does dispatch variation void the warranty, or is throughput flexibility locked to an agreed SOC, DoD, C-rate, and temperature envelope? If the OEM discontinues the cell line, is there an equivalence clause — or does the warranty hollow out with it? SHIELD maps enforceability year by year against your actual exposure.

Cell, Thermal & Fire Safety Gaps

High DCIR means faster degradation and thermal runaway risk. High cell-to-cell variance means your weakest cell limits the entire rack. But beyond cell quality — does your contract specify fire safety scope clearly? UL 9540A testing, NFPA 855 compliance, deflagration venting, and gas detection obligations are often assumed but not contractually assigned. SHIELD identifies where quality and safety thresholds are missing, too loose, or ambiguously scoped.

LDs, Exclusions & Interface Scope

Are your liquidated damages actually protective — or just decorative? SHIELD stress-tests your LD structure across 6 categories and identifies where caps are too low, where remedies don't bite, and where carve-outs quietly void the guarantees you thought you had. It also maps the interface scope: where does the OEM's obligation end and yours begin? In multi-vendor builds, ambiguity at the BMS–PCS–EMS boundaries is the most common cause of grid-connection delay — and where most post-COD disputes originate.

Portfolio IRR Optimization

The objective is the portfolio's equity IRR, not a ranking of individual sites. Plants interact — through shared evacuation, connectivity limits, and phasing — and MESH-T solves them together in one optimization.

Connectivity & Evacuation Allocation

Which capacity goes to which substation, and what congestion and curtailment will cost there. Capex against evacuation trade-offs made explicit, before the connectivity applications are filed.

Asset Placement

Solar, wind, and storage placed against resource quality, connectivity, and tariff together. The best wind site is not always the best project, and the difference is quantifiable.

Phasing & Capex Trade-offs

Build order across the portfolio, modeled against falling BESS prices and evacuation availability. Includes battery value under constrained evacuation, where storage earns its place by shifting rather than adding energy.

RE Mix & Sizing

Optimal solar, wind, and BESS combination for the load being served — one facility or a portfolio of consumers on 15-minute profiles. Contract demand, ToD structure, and seasonal shape modeled per consumer; the mix is solved against the aggregate.

Structure & Interconnection

Third-party open access and group captive compared across interconnection routes from 33 kV DISCOM-connected to 220 kV ISTS — with the full state charge and loss cascade priced for each: transmission, wheeling, CSS, additional surcharge, standby, and electricity duty.

Tariff & Savings

Landed cost per unit computed against each consumer's DISCOM bill, including ToD arbitrage and demand charge impact. Outputs the PPA tariff that holds the generator's IRR while maximizing annual savings for every consumer served.

Regulatory Sensitivity

Savings tested across surcharge revisions, banking restrictions, grid tariff escalation, and load growth assumptions. Results delivered as P50/P90 bands, not a single-point estimate.

Grounded in Plant Data

Team experience includes commissioning multiple utility-scale BESS projects across India. Every constraint in the model comes from observed plant behaviour.

IEX Native

Trained on 18+ months of real IEX DAM and RTM data. Indian calendar awareness — Republic Day, Diwali, monsoon surplus, summer peaks — baked in.

Warranty as a Hard Constraint

The OEM operating envelope is mathematically enforced inside the formulation, so the optimizer cannot produce a violating schedule.

PPA First, Then Merchant

Contractual obligations are met first, and merchant upside fills the remaining capacity. Lenders see compliant dispatch; investors see protected returns.

Dispatch Optimization — Merchant BESS

Physics-unaware dispatch was degrading the battery faster than the revenue justified. PRISM captures more and degrades less — automated before the DAM deadline, every day.

100 MW FDRE — Sizing Evolution

A wind-heavy mix hit 24% P50 EIRR with a wide P50–P90 spread; as BESS prices fell, a solar + storage mix gave up 2pp for dramatically less variance. Lenders price variance ahead of the best case.

BESS Augmentation — DC vs AC Coupling

The client's model staggered augmentations across several years. One right-sized augmentation, with the preferred coupling, was the IRR-accretive answer.

RTC Bid — Go/No-Go Decision

The Monte Carlo EIRR distribution ran from 3% to 12% — even the best case fell short of the equity hurdle. Sometimes the best bid advisory is not to bid.

Wind Asset Distribution — Multi-Site

The client ranked wind sites by CUF. Ranked by project-level IRR — connectivity, evacuation and tariff included — the order flipped entirely.

BESS Placement — Solar vs Wind Co-location

Solar co-location meant predictable DAM capture; wind meant better RTM spreads. The quantified IRR delta settled in one number what intuition had debated for months.

BESS Contract — The PBG Cliff

Physics models showed underperformance surfacing from year six — after the performance bank guarantee had already stepped down in year three. The PBG schedule was restructured before signature.

C&I Supply — Two-Sided Optimization

COMPASS holds the generator's equity IRR at target while the RE mix and consumer allocation maximize savings on every load profile — the solar, wind and BESS proportions tabulated against each consumer's share. One-sided sizing leaves money on the table for both.

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.

Bid Stage

Contract & Build

Operate

FDRE / Hybrid IPPs

Independent power producers with firm delivery renewable energy contracts. Your bid-stage equity IRR assumes optimal dispatch — PRISM delivers it within the PPA and warranty constraints.

Tier 2 Hyperscalers

Data center operators scaling capacity with hybrid RE PPAs to meet sustainability and RPO commitments. The 24/7 clean energy matching problem is structurally identical to FDRE dispatch — same optimization, different buyer.

C&I Supply

Developers structuring group captive and open-access supply, and the manufacturers and commercial operators they serve. COMPASS solves both sides — generator IRR held at target, consumer savings maximized across load profiles — before the PPA is signed.

Lenders & Investors

Project finance institutions and equity investors needing independent technical diligence on BESS and hybrid assets. Dispatch assumption validation, degradation modeling, and bankability assessment from someone who's built and operated these systems.
