Battery Energy Storage Systems (BESS)

Deliver BESS projects that are safe, grid-ready, and acceptance-clean. Sizing, integration, and commissioning discipline that protects COD, performance guarantees, and warranties.

BESS EPC delivery without safety gaps or grid surprises

Battery storage projects fail late at interconnection, safety sign-off, or commissioning when interfaces and evidence are weak. MetRenew supports owners, developers, and EPC teams with delivery governance across sizing inputs, OEM/integrator coordination, safety requirements alignment, and grid compliance readiness. The outcome is practical control: clearer specs, fewer interface failures, stronger test plans, and documentation that stands up to acceptance and warranty handover so your BESS energizes safely, performs as contracted, and transitions cleanly into operations.

Our Solutions

Sizing & Integration Basis (MW/MWh)

Align duration, duty cycle, degradation assumptions, and service requirements (energy shifting, peak, ancillary services) to the interconnection path and commercial model. We help translate “what the project must do” into a defensible sizing and integration basis that engineering, procurement, and commissioning can execute.

OEM / Integrator Technical Specs & Compliance Matrix

Build clear technical requirements for PCS, transformers, protection, EMS, SCADA/communications, and balance-of-plant. We structure compliance matrices and evidence expectations so vendor proposals are comparable, gaps surface early, and acceptance criteria are designed into procurement not argued at the end.

Safety & Code Readiness

Establish safety-by-design requirements: layout and separation, detection and suppression strategy, emergency response interfaces, and hazard analysis inputs aligned to local authority and site conditions. The goal is predictable approvals, safer construction, and commissioning that doesn’t stall on safety sign-off.

Interface & Construction Governance

Control the handoffs that typically break BESS delivery civil works to container placement, cabling to protection settings, PCS to EMS controls, and SCADA to grid communications. We apply interface registers, quality gates, and punch-list discipline to reduce rework, site clashes, and last-mile delays.

Commissioning, Testing & Warranty-Clean Handover

Plan commissioning backward from energization and acceptance: FAT/SAT governance, test protocols, performance validation, and documentation completeness. We help teams exit construction with clean evidence packs baseline performance data, as-builts, settings files, and warranty-ready handover into O&M.

Use Cases & Outcomes

Utility-Scale BESS for Capacity + Peak Shaving

Standalone storage where COD depends on clean integration across PCS, transformers, protection, and controls. Outcome: predictable energization, acceptance-ready test sequencing, and verified performance against power, duration, and availability criteria.

Renewable Hybrid (Solar/Wind + BESS) Integration

Hybrid plants where PPC/EMS logic, SCADA telemetry, and grid-code behavior must align across PV/wind and storage. Outcome: fewer integration defects, cleaner commissioning, and a plant that performs as one controllable system.

Grid Services and Fast Response Applications

Projects targeting frequency response, ramping support, and grid support services with strict response requirements. Outcome: controls tuned to dispatch needs, test protocols aligned to grid requirements, and evidence packs that support compliance and acceptance.

Safety-Critical Sites and Authority Sign-Off

Sites where safety approvals can block energization without defensible documentation (layout, hazard analysis, detection/suppression strategy, emergency response interfaces). Outcome: safety-by-design readiness and commissioning that doesn’t stall on missing evidence.

Why Metrenew

Commissioning-first delivery controls

We work backward from FAT/SAT, energization, and acceptance so engineering, procurement, and site execution align to measurable pass/fail criteria.

Interface risk discipline across OEMs/integrators

Clear interface registers and RACI across EPC, OEMs, integrators, SCADA/EMS, and grid stakeholders reducing last-mile integration failures that delay COD.

Warranty-clean documentation

Traceable QA/QC, test records, settings files, and as-builts that hold up in handover, warranty conditions, and operational troubleshooting so performance is provable, not debated.

Frequently Asked Questions

What does MetRenew cover in BESS EPC support?

We support delivery governance across sizing inputs, technical requirements, interface management, safety readiness, commissioning planning, and acceptance documentation. The scope is structured to reduce late-stage rework and ensure the project is grid-ready, safely energizable, and warranty-clean at handover.

Do you help with BESS sizing (MW/MWh) and performance assumptions?

Yes. We help define the sizing and operating basis duration, duty cycle, degradation, efficiency, and dispatch requirements so engineering and procurement decisions match the commercial model and interconnection realities. The intent is to prevent costly redesigns and underperformance risks.

How do you address BESS safety and permitting risk?

We align safety-by-design requirements with local authority expectations and site conditions, including layout, separation, hazard analysis inputs, detection/suppression strategy, and emergency response interfaces. The goal is predictable approvals and commissioning that doesn’t stall on safety sign-off or missing evidence.

How do you ensure grid compliance and interconnection readiness?

We support protection and controls readiness, communications/SCADA integration, and test planning aligned to grid code requirements and acceptance criteria. This reduces “surprises at energization” and makes it easier to demonstrate compliance through documented tests and settings evidence.

What commissioning and testing evidence is critical for acceptance and warranties?

Clear protocols, SAT results, performance and availability validation, settings files, as-builts, and complete punch-list closure are key. We help teams assemble an evidence pack that supports contractual acceptance, warranty conditions, and an operationally usable handover.

Do you support hybrid projects (solar + storage)?

Yes. We help manage cross-tech interfaces plant controller logic, SCADA/EMS integration, grid compliance testing, and coordinated commissioning so hybrid projects behave as one system during acceptance and in operations.

How do you reduce schedule slippage in storage projects?

By putting controls early: vendor readiness checks, interface registers, quality gates, procurement evidence discipline, and commissioning-first sequencing. This prevents late-stage firefighting where delays compound and change orders become unavoidable.

What do you need from us to start?

A high-level single-line diagram, site/layout constraints, commercial operating intent, interconnection requirements (or status), and current vendor/EPC structure. If documentation is early-stage, we can start with a delivery readiness assessment and define the control plan.
