ESS Delivery Project Manager - UK in Milton Keynes

About Sungrow UK is powering the energy transition, one battery at a time. We need an ESS Delivery Project Manager to ensure our energy storage projects are delivered with excellence, from contract signature to final commissioning and handover.

Responsibilities

• Lead the full lifecycle delivery of utility‑scale and C&I Battery Energy Storage System (BESS) projects across the UK – owning scope, schedule, budget, and quality from kick‑off to handover.
• Act as the primary point of contact for clients, EPCs, system integrators, investors, and technical advisors throughout the entire project journey, building trust at every milestone.
• Coordinate cross‑functional internal teams – including engineering, supply chain, logistics, and service – as well as external contractors and subcontractors, keeping everyone aligned and moving forward.
• Develop and maintain detailed project plans, risk registers, delivery schedules, and commissioning documentation, ensuring full traceability and audit readiness at all times.
• Oversee payment milestone tracking, change management processes, and contract compliance, proactively flagging and resolving deviations before they escalated.
• Support and attend Factory Acceptance Tests (FAT) and Site Acceptance Tests (SAT) alongside customers, ensuring quality standards are met at every stage.
• Monitor UK ESS market developments, regulatory requirements, and grid connection standards, ensuring projects remain compliant with applicable codes and certifications.
• Drive continuous improvement within the ESS delivery function, contributing lessons learned and best practices to strengthen the team’s capability over time.

Qualifications

• A degree in Electrical Engineering, Power Systems, Renewable Energy, or a comparable technical field.
• At least 3‑5 years of hands‑on project management experience in the energy storage, solar PV, or broader renewable energy sector; experience with EPC companies or BESS manufacturers is a strong advantage.
• Solid technical understanding of Battery Energy Storage Systems (BESS), including PCS, BMS, grid connection requirements, and utility‑scale storage architecture.
• Proven ability to manage multiple concurrent projects in a fast‑paced, international environment, with strong attention to detail and organisational discipline.
• Excellent stakeholder management and communication skills – equally confident presenting to investors, walking a construction site, or aligning with colleagues overseas.
• Project management certifications such as PMP, PRINCE2, or CAPM are highly desirable.
• English C1 proficiency is required; additional European languages or Mandarin are a plus.
• A proactive, solutions‑first mindset – you anticipate problems, act decisively, and keep the project moving no matter what.
• Willingness to travel within the UK and occasionally internationally (up to 30‑40% travel expected).

Benefits

• A front‑row seat in the UK’s rapidly growing battery energy storage market, working on large‑scale projects that shape the country’s energy future.
• A collaborative, international team culture where your expertise is valued, your growth is supported, and your ideas genuinely make a difference.
• Competitive salary and an attractive performance‑based bonus structure tied to clear, agreed KPIs.
• Real career progression pathways within a global greentech leader – Sungrow is the world’s largest PV inverter manufacturer, operating in over 60 countries.
• Access to technical and commercial training, including opportunities to engage with our R&D headquarters and ESS innovation teams worldwide.
• A dynamic, purpose‑driven workplace where every project you deliver brings the UK one step closer to a fully clean grid.
