What Does a Commissioning Engineer Actually Do?
23 Sept, 2026
The global energy system is changing, and engineers are at the centre of that transformation.
Wind farms, solar developments, Battery Energy Storage Systems and expanding electricity networks all require specialist professionals to take projects from early design through construction, commissioning and operation.
For engineers, this is creating career opportunities across a growing range of technologies and disciplines.
But which roles are helping turn renewable energy ambitions into working infrastructure?
Electrical Engineers
Electrical Engineers are essential across almost every area of renewable energy.
They can work on electrical design, power distribution, substations, cables, equipment specification and the integration of renewable generation into wider electricity networks.
Opportunities exist across wind, solar, battery storage and transmission projects.
As energy systems become increasingly electrified, professionals with strong electrical engineering experience are likely to remain an important part of project teams.
Grid Connection and Power Systems Engineers
Building renewable generation is only useful if that electricity can reach the network.
Grid Connection Engineers help developers understand how new projects can safely and effectively connect to existing electricity infrastructure.
Power Systems Engineers can work across areas such as network modelling, system stability and power flows.
As more renewable generation connects to electricity networks, these skills are becoming particularly valuable.
Civil and Structural Engineers
Renewable energy projects require substantial physical infrastructure.
Civil and Structural Engineers can be involved in turbine foundations, access roads, substations, drainage, solar structures and other supporting infrastructure.
Offshore developments introduce additional requirements, including foundations and structures capable of operating in demanding marine environments.
Their work helps ensure renewable assets remain safe and reliable throughout their operational life.
Battery Energy Storage Specialists
Battery Energy Storage Systems are creating another area of opportunity within renewable energy.
BESS projects require expertise across electrical systems, controls, grid integration, safety and commissioning.
Engineers may work on the design of battery facilities, connection infrastructure, control systems or the integration of storage alongside renewable generation.
As battery deployment increases, experience combining power engineering with energy storage technology could become increasingly valuable.
Project Managers
Renewable energy developments bring together engineering teams, contractors, suppliers, investors and regulatory bodies.
Project Managers are responsible for coordinating these different elements and keeping delivery moving.
Their responsibilities can include budgets, programmes, resources, procurement, contractors and risk.
Professionals with experience delivering complex engineering or infrastructure projects may also find their skills transfer effectively into renewable energy.
Project Controls Professionals
Behind every major project is a detailed programme.
Planners, Cost Engineers and Project Controls professionals help organisations understand whether projects are progressing according to schedule and budget.
They monitor costs, resources, milestones and risks while providing information that helps project leaders make informed decisions.
As renewable projects increase in scale and complexity, strong project controls can become critical to successful delivery.
Commissioning Engineers
Before a renewable energy asset becomes operational, its systems need to be tested.
Commissioning Engineers help verify that equipment has been installed correctly and performs as intended.
Electrical, mechanical and controls specialists can all be involved depending on the project.
Commissioning professionals often work towards the end of construction, helping bridge the gap between project delivery and operations.
Offshore and Subsea Engineers
Offshore wind creates opportunities for professionals with specialist marine and offshore expertise.
Roles can involve foundations, subsea cables, installation engineering, marine operations and offshore substations.
Floating offshore wind could expand these requirements further, particularly across areas such as mooring systems, dynamic cables and floating structures.
This also creates opportunities for professionals transferring expertise from other offshore industries.
Health, Safety and Environment Professionals
Renewable energy projects can involve heavy construction, high-voltage equipment, offshore operations and complex installation activities.
Health, Safety and Environment professionals help ensure these activities are managed responsibly.
Their work can include risk assessments, site inspections, environmental requirements and developing safe systems of work.
Strong HSE expertise is essential throughout construction, commissioning and operations.
Could Your Engineering Skills Transfer into Renewables?
A career in renewable energy does not always require previous renewable experience.
Professionals from power generation, utilities, infrastructure, construction, marine engineering and other technically complex sectors can already possess many of the skills employers need.
Electrical engineering, project management, commissioning, construction and project controls expertise can often transfer between industries.
Understanding these transferable skills can open new career opportunities while helping renewable energy employers access a wider pool of experienced professionals.
