Utility Scale Battery Storage
Large-Scale and Utility-Scale Battery Energy Storage Systems (BESS)
Utility-scale battery energy storage has become nearly essential to a more flexible, resilient, and reliable electric grid. Core Development Group provides comprehensive Engineering, Procurement, and Construction (EPC) services for large-scale and utility-scale battery energy storage systems (BESS), helping IPPs and project owners turn complex energy-storage opportunities into operating assets.
From early engineering and planning to equipment procurement through construction, commissioning, and energization, our team brings the experience, technical expertise, and field execution capabilities needed to deliver large-scale battery storage projects safely, efficiently, and reliably.
Building the Infrastructure Behind Grid-Scale Storage
Utility-scale battery storage can help balance supply and demand, support renewable generation, improve grid reliability, and provide critical flexibility as electricity markets continue to change. Core Development Group works with independent power producers, utilities, asset owners, and energy companies to design, build, and deliver the infrastructure required to bring these large energy storage projects online.
Our group understands the unique challenges associated with large-scale BESS construction – including complex electrical systems, equipment integration, interconnection requirements, site conditions, logistics, and coordination across multiple project stakeholders. We design and build large-scale battery storage systems with the infrastructure that enables them to perform.
Comprehensive BESS EPC Services
Core Development Group provides end-to-end EPC services designed to move utility-scale battery storage projects from plans to power.
Engineering
Our engineering team develops practical, construction-ready solutions for complex battery storage facilities. We coordinate electrical, civil, structural, and site infrastructure requirements while working closely with owners, developers, equipment suppliers, utilities, and other project stakeholders.
Procurement
Successful BESS projects depend on the right equipment, delivered at the right time. Our procurement and project management teams coordinate critical equipment and materials, manage suppliers, and support project schedules to keep construction moving.
Construction
Our experienced construction team provides field leadership and execution for utility-scale battery storage projects. We manage site preparation, equipment installation, electrical infrastructure, balance-of-system construction, and coordination of subcontractors and project partners.
Commissioning & Energization
Getting a battery system built is only part of the job. We coordinate testing, commissioning, system integration, and energization activities to help transition projects from construction into operation.
Batteries Designed for Grid Support
Utility-scale battery storage can provide critical services across the power system.
- Energy shifting: Store electricity when supply is abundant and discharge when it is needed.
- Renewable integration: Increase the flexibility and value of solar and other renewable generation.
- Grid stabilization: Support grid frequency, voltage, and overall system reliability.
- Peak demand support: Provide additional capacity during periods of high electricity demand.
- Resilience: Strengthen the ability of energy infrastructure to respond to changing grid conditions.
- Market participation: Enable projects to participate in energy, capacity, and ancillary-service markets where applicable.
Built for Large Complex Energy Projects
Every utility-scale BESS project has its own challenges. Site conditions, interconnection requirements, equipment selection, permitting, supply-chain constraints, construction logistics, scheduling, and evolving project requirements can all affect execution.
Our approach is built around collaboration, accountability, and proactive problem solving. Our goal is simply to help our clients get their energy projects built, energized, and operating on-time and on-budget.
Whether paired with a renewable energy project, developed as a standalone storage facility, or deployed to provide critical grid-support capabilities, utility-scale battery storage is an important part of the future energy infrastructure. From engineering and procurement to construction and energization, we deliver the expertise and execution needed to move utility-scale battery storage projects forward.Get Experience That Moves Projects Forward
Large-scale battery storage projects require more than equipment and engineering. They require experienced project execution. Core Development Group brings together engineering, procurement, construction, and project management capabilities under one EPC partner. Our team understands how decisions made during development and engineering can affect procurement, construction, schedule, cost, commissioning, and long-term project performance.
