System architecture & design
Technology-agnostic definition of a coherent, buildable BESS solution.
- AC- and DC-coupled architectures
- Power and energy sizing
- Equipment selection and specifications
- Site layouts and design basis
LK EngineeringDiscuss a projectBattery energy storage systems
Utility-scale BESS engineering & design.
Independent technical support for developers, investors and EPC contractors—turning complex battery, power-conversion and grid interfaces into coordinated, delivery-ready projects.
Integrated technical thinking
More than a collection of equipment.
A successful battery project depends on the interfaces between cells, containers, PCS, transformers, switchgear, protection, controls and the grid. LK Engineering brings these disciplines together into one coordinated technical solution.
Our work is shaped by hands-on project delivery. We focus on decisions that improve constructability, expose interface risk early and give owners and delivery teams clear technical control.
Technology-agnosticIndependent advice aligned with the project—not a product.
Delivery-focusedEngineering developed with construction and commissioning in mind.
Grid-awarePlant design coordinated with network and compliance requirements.
Commercially consciousTechnical decisions considered against programme, risk and value.
BESS capabilities
Engineering the interfaces that determine project success.
Focused technical support can be provided as a defined work package, embedded engineering resource or independent owner’s engineer.
Electrical balance of plant
Coordinated electrical design from battery terminals to the grid connection.
- Single-line diagrams and cable sizing
- LV, MV and HV systems
- Earthing and lightning protection
- Auxiliary power and load schedules
Grid, protection & controls
Clear interfaces between plant equipment, network requirements and site control systems.
- Grid-code and G99 support
- Protection philosophy and coordination
- PPC, EMS, SCADA and BMS interfaces
- DNO and TSO technical coordination
Assurance & commissioning
Independent challenge and practical support through procurement, construction and energisation.
- Tender and supplier evaluation
- Design review and technical assurance
- FAT, SAT and commissioning plans
- Performance and compliance testing
Project lifecycle
Continuity from concept to energisation.
Keeping technical intent connected across the project lifecycle reduces late design changes, unclear responsibilities and avoidable commissioning delays.
Develop
Feasibility, system architecture, grid strategy, project requirements and early risk definition.
Procure
Employer’s requirements, technical specifications, tender evaluation and contract interface support.
Design
Coordinated detailed engineering, calculations, reviews and construction-ready deliverables.
Deliver
Construction support, commissioning planning, grid compliance and technical close-out.
Independent assurance
Technical clarity for owners and delivery teams.
DevelopersBuild a credible technical basis before procurement and financial commitment.
InvestorsUnderstand technology, integration and delivery risks before they affect value.
EPC contractorsStrengthen design coordination, interfaces and grid-compliance delivery.
Asset ownersProtect performance and resolve technical gaps through commissioning and operation.
