Project Management perspective — Terry Parsons, PQMS
Battery Energy Storage System projects bring together civil works, electrical infrastructure, specialist equipment, grid interfaces, commissioning activities and demanding handover requirements. The Project Manager’s role is to keep those moving parts aligned from the first definition of scope through to final closeout.
Good Project Management is not simply reporting progress after the event. It creates the structure that allows decisions to be made early, responsibilities to remain visible and emerging risks to be dealt with before they affect safety, programme, cost or quality.
1. Establish control during pre-construction
The strongest opportunity to protect a BESS project comes before construction begins. This is when the delivery team must turn the commercial and technical objectives into a workable scope, programme and responsibility structure.
- Confirm the project scope, interfaces and acceptance requirements.
- Review design maturity and identify information still required for construction.
- Build a realistic programme around approvals, procurement, access, construction, testing and grid milestones.
- Identify critical-path activities and the dependencies between contractors, OEMs, ICPs and the DNO.
- Record key risks, assign owners and agree practical mitigation actions.
- Align the Project Quality Plan and inspection regime with the delivery programme.
A programme is only useful when it reflects how the work will actually be delivered. Dates without clear dependencies, owners and decision points create the appearance of control without providing it.
2. Manage interfaces, not just individual contracts
Many delays occur between packages rather than within them. The battery supplier may depend on civil completion; commissioning may depend on protection settings, communications and approved test documentation; energisation may depend on DNO approvals and outage availability.
The Project Manager should maintain an interface register showing what must pass between parties, who owns each action and when the information or physical work is required. Interface meetings should focus on unresolved decisions and upcoming dependencies rather than repeating general progress updates.
3. Keep the programme connected to field reality
During construction, progress must be tested against evidence from the site. Reported percentages alone can hide incomplete prerequisites, unapproved changes or work that has not passed the required inspection stage.
- Review short-term look-ahead plans against the master programme.
- Confirm that labour, materials, design information and access are available before activities start.
- Track constraints and decisions with named owners and due dates.
- Coordinate contractor sequencing to prevent one package from obstructing another.
- Use quality records and completed inspection points as part of progress verification.
- Escalate emerging critical-path threats while recovery options still exist.
4. Control change openly
Energy projects change. The important question is whether the consequences are understood before the change is accepted. A useful change-control process records the reason, technical impact, programme effect, commercial implication, quality requirements and approval route.
Informal instructions and assumptions are particularly dangerous at contractor interfaces. Decisions should be documented and communicated to every party affected by them.
5. Treat commissioning and energisation as a managed phase
Commissioning is not a final task added to the end of construction. It requires its own plan, sequence, responsibilities, prerequisites and evidence. The Project Manager coordinates the parties; the Quality Manager verifies that the required records and acceptance evidence are complete.
- Define system boundaries and the commissioning sequence.
- Confirm construction completion and outstanding defects.
- Coordinate OEM, contractor, DNO and client attendance.
- Track test procedures, results, approvals and retests.
- Manage energisation readiness and the conditions attached to it.
- Keep the commissioning programme connected to handover-document status.
6. Plan handover from the beginning
Handover problems usually accumulate over the project rather than appearing at the end. The required dossier structure, O&M information, Health and Safety file inputs, test records, certificates, as-built drawings and defect-closeout evidence should be defined early and tracked throughout delivery.
A successful closeout means more than reaching energisation. The client should receive a controlled asset, complete evidence, understood residual actions and a clear record of lessons learned.
The practical test
At any point in the project, the management team should be able to answer five questions: What is the current position? What is due next? What could prevent it? Who owns the action? What evidence will demonstrate completion?
When those answers remain visible from feasibility to handover, Project Management provides genuine control rather than retrospective reporting.
