Employment Type: Full-Time, Permanent
Salary: Competitive, based on experience and qualifications
Role Overview:
We are seeking an experienced and technically proficient BESS Development Manager to lead and manage the technical execution and coordination across all phases of utility-scale Battery Energy Storage System (BESS) projects. The successful candidate will play a pivotal role in bridging project development, engineering, construction, and operations to ensure successful and compliant delivery of energy storage solutions.
This is a multidisciplinary role involving technical design, vendor evaluation, stakeholder engagement, grid integration, and continuous improvement, ideally suited to candidates with a strong background in electrical engineering, energy storage systems, and power system integration.
Key Responsibilities:
Pre-Development Phase - Technical Planning
- Evaluate, compare, and recommend appropriate BESS technologies and configurations based on project-specific requirements (e.g. duration, capacity, environmental conditions).
- Develop preliminary system design concepts and configuration plans to meet grid code and project performance objectives.
- Coordinate early-stage grid compliance assessments with DNOs, TSOs, and grid consultants, ensuring feasibility and risk mitigation from the outset.
Development Phase - Design & Procurement
- Define detailed technical specifications for BESS systems, SCADA/EMS, and supporting infrastructure.
- Lead technical workstreams during the EPC and BESS vendor selection process, including bid evaluation, compliance assessment, and technical clarifications.
- Conduct and coordinate thorough reviews of vendor proposals for technical compliance, warranty conditions, and long-term performance expectations.
- Support the planning and execution of Factory Acceptance Tests (FAT) and Site Acceptance Tests (SAT), ensuring milestones are achieved to specification and quality standards.
- Review design documentation for completeness and integration readiness, including BoP (Balance of Plant) engineering, SCADA integration, and interface with grid systems.
- Oversee and provide technical support during site installation and commissioning phases, ensuring execution matches design intent.
Technical Stakeholder Coordination
- Act as the lead technical interface for EPCs, BESS vendors, DNOs, consultants, and other technical advisors throughout the project lifecycle.
- Represent the technical team in key meetings, ensuring alignment between technical deliverables and project goals.
- Work closely with internal Project Managers to monitor technical progress and align with construction schedules and milestones.
Operational Feedback & Technical Optimisation
- Collaborate with O&M teams to review operational performance data and identify areas for improvement or design enhancements.
- Integrate lessons learned from commissioned assets into the design and specification of future projects.
- Support root cause analysis for operational issues and coordinate corrective actions with vendors and O&M providers.
Additional Technical Responsibilities
- Contribute to risk assessments, lifecycle cost evaluations, and bankability reviews of BESS configurations.
- Define strategies for asset monitoring, remote diagnostics, and long-term performance measurement using KPIs.
- Stay informed of evolving regulatory, grid, and technology developments affecting BESS design, integration, and operation.
Required Skills & Experience:
- Degree in Electrical Engineering, Energy Systems, or related technical discipline (Master's preferred).
- Proven experience in utility-scale BESS project development and technical management.
- Strong knowledge of BESS technology, SCADA/EMS systems, and grid integration principles.
- Solid understanding of UK grid codes, DNO/TSO processes, and connection agreements.
- Experience coordinating with EPCs, OEMs, and system integrators.
- Ability to interpret technical documentation, perform engineering reviews, and engage in technical negotiations.
- Excellent stakeholder management, communication, and reporting skills.
Desirable:
- Chartered Engineer (CEng) or working towards professional registration.
- Familiarity with HV and MV electrical infrastructure.
- Experience in Factory and Site Acceptance Testing.
- Understanding of battery warranties, degradation models, and performance guarantees.
- Experience working in fast-paced, multidisciplinary energy environments.
What We Offer:
- Competitive salary and benefits package
- Hybrid or remote working options
- Opportunities for growth in a rapidly expanding sector
- Collaborative, mission-driven company culture
