Engineering Flexible, Resilient and Future-Ready Energy Systems

Engineering Flexible, Resilient and Future-Ready Energy Systems

Energy storage is becoming a fundamental component of modern electricity systems. As renewable generation expands and power networks become more dynamic, storage provides the flexibility required to balance supply and demand, manage intermittency, strengthen resilience, improve power quality and optimise energy costs.

Great Standard Consulting Ltd supports utilities, developers, investors, industrial organisations and infrastructure owners in evaluating, designing, integrating and delivering energy-storage solutions. Our approach combines electrical engineering, system modelling, grid integration, controls, safety, techno-economic analysis and project delivery considerations.

Our capability covers Battery Energy Storage Systems (BESS) for grid-scale, renewable-integrated, behind-the-meter, microgrid, backup and critical-infrastructure applications, while also considering alternative storage technologies where project conditions require them.

Why Energy Storage Matters

Electricity systems increasingly need flexibility. Renewable generation varies with weather, demand changes throughout the day, networks experience congestion and critical facilities require continuity of supply. Properly engineered storage can respond rapidly to these challenges, but project value depends on selecting the right application, power rating, energy duration, operating strategy, technology, connection arrangement and control philosophy.

GSC helps clients define the business and technical case before committing to a system architecture, reducing the risk of oversizing, undersizing or selecting storage that does not match the intended duty cycle.

Our Energy Storage & BESS Services

Integrated with Renewables, Smart Grids and Industrial Energy Systems

BESS rarely operates in isolation. GSC can integrate storage with solar PV, wind, smart grids, industrial facilities, microgrids, backup generation, digital energy platforms and green-hydrogen systems. This multidisciplinary approach allows storage to be engineered around the wider energy system rather than treated as a standalone equipment package.
