Role Overview:

The Site Manager is the overall on-site lead during the delivery phase of a utility-scale BESS project, responsible for site safety, schedule, quality, interface coordination and final delivery outcomes.

Its primary responsibility is to coordinate all relevant teams and ensure that the site is ready for commissioning, acceptance and final handover.

Responsibilities:

• Manage the end-to-end on-site delivery of utility-scale BESS projects, covering equipment receipt, installation, cold commissioning, hot commissioning, grid connection, Site Acceptance Testing (SAT) and final handover.
• Serve as the primary HSE representative on site, managing the safety performance of personnel and subcontractors, and coordinating risk assessments, work approvals and site inspections.
• Develop and track the overall site delivery schedule and key milestones, coordinating site personnel, technical experts, subcontractors and equipment suppliers.
• Manage site integration and interfaces among the EPC, PCS, EMS, SCADA, substation and other relevant parties, ensuring clear responsibilities and prerequisites.
• Verify installation quality and commissioning readiness, organize readiness reviews and release gates for cold commissioning, hot commissioning, energization and grid connection.
• Act as the primary on-site interface with the customer, align external communications, manage customer expectations and coordinate testing, acceptance and issue resolution.
• Manage site issues, risks and changes through issue registers and action plans, and elevate major risks to internal management when required.
• Ensure the completeness and traceability of acceptance documents, test records, issue-closure evidence and handover documentation.
• Support commissioning-related pre-sales activities, including tender document review, commissioning scope and responsibility assessment, technical bid responses, risk identification and participation in customer clarification meetings.
• Coordinate customer training, punch‑list closure, project handover and lessons‑learned reviews to ensure on‑time project acceptance.

Qualifications:

• Bachelor's degree or above in Electrical Engineering, Power Systems, Automation, Energy Engineering, Renewable Energy or a related discipline.
• At least five years of experience in power, renewable energy, BESS or large-scale engineering projects, including at least two years in site management or project delivery management.
• Familiarity with the full delivery lifecycle of utility-scale BESS projects, from equipment receipt and installation through commissioning, grid connection, acceptance and handover.
• General knowledge of BESS, BMS, PCS, EMS, SCADA, fire suppression, thermal management, substations and auxiliary systems.
• Ability to read and understand electrical single‑line diagrams, secondary schematics, communication topology diagrams, commissioning procedures and SAT documentation.
• Strong capabilities in schedule management, risk identification, issue resolution, on‑site decision‑making and cross‑functional coordination.
• Ability to review tender documents and technical specifications and support commissioning plans, technical bid responses and customer clarifications.
• Strong customer communication skills and the ability to coordinate EPCs, equipment suppliers, subcontractors and internal teams.
• Proficiency in English for business meetings, technical communication and written reporting; fluency in Mandarin Chinese.
• Willingness to undertake long‑term overseas assignments and work at project sites across Europe and other regions.

Preferred Skills:

• Full‑cycle delivery experience in utility‑scale BESS, solar, wind or substation projects;
• Experience as a Site Manager or on BESS projects of 100 MWh or above;
• Familiarity with European HSE, grid‑connection and site compliance requirements;
• Experience in overseas projects or international customer management;
• Proficiency in German, Spanish, French or another European language.
