02SizeBattery sizing and techno-economic analysis set capacity.
03Study the ConnectionGrid integration and protection in charge and discharge.
04Design and SpecifySystem, protection and energy management design.
05CommissionPerformance testing before handover.

Inputs and Deliverables.

A practical starting point and the Engineering outputs to agree for your Project.

01 / Starting information

What We Need from You

  • Required duty cycle, operating strategy and target availability
  • Target power, energy and duration if known
  • Connection point, voltage and utility fault data where available
  • Associated generation, site constraints and battery vendor data if selected
  • Applicable grid code, safety requirements and Client specifications

Send what is available. We will identify missing information before confirming the scope and programme.

02 / Agreed outputs

What You Receive.

  • Sizing basis and techno-economic assessment where commissioned
  • Grid integration study report where included
  • Single-line diagrams and equipment layout
  • Protection philosophy and setting calculations
  • Energy management architecture and equipment specifications
  • Performance test reports when testing is included

The exact deliverables are fixed in the agreed scope for each Project.

Standards and Compliance.

We engineer to the standards and regulations that govern your Project, fixed in the design basis.

International StandardsIEC, IEEE, ISO, ASME and API standards, as the Project requires.
National CodesThe codes of the country where the asset is built: BIS and CEA in India, NEC in the USA, BS in the UK, EN in Europe, AS/NZS in Australia, GSO and SASO in the Gulf.
Utility & Authority RequirementsGrid codes, utility specifications and the approvals of the connecting authority.
Client & Lender SpecificationsOwner, licensor and lender requirements, fixed in the design basis.

Typical references for this Service: IEC 62933, IEC 62619, UL 9540A, NFPA 855.

Applicable standards and editions are agreed and fixed in each Project's design basis.
