Wind energy is a proven and mature technology which has seen significant growth in recent years. With advancements in wind turbine technology and the sharply falling costs, there remains huge potential and opportunity for development.

Green Cat has vast and varied experience of onshore wind across almost 350 unique sites. Whether it be multi megawatt wind farms, community wind projects, small scale agricultural projects or wind turbines directly supplying a high energy demand user, we tailor our services to the needs of the customer and to an appropriate level of detail for the project.

Green Cat offers a complete in-house consultancy and project management service to deliver wind energy projects through the whole life-cycle from initial conception to operation.

Our Services Include:

  • Initial feasibility, including site selection and concept development.
  • Detailed project constraints mapping, project design and optimisation.
  • Wind monitoring and wind resource assessment.
  • Grid connection application, technical advice and management.
  • Project consenting, including environmental assessment, public consultation and noise assessment.
  • Engineering construction management, including contract management, procurement, health and safety and construction supervision.
  • Due diligence and technical advisory services.
  • Operational asset management.


Green Cat has a wide portfolio of experience in the engineering, planning, design development, delivery and finance of ground-mounted solar farms and rooftop installations, spanning over 200MW across 35 projects.

Our capabilities include consenting, conditions discharge/management, solar resource assessment including whole of life forecasting, EPC and O&M contract procurement and technical negotiations, grid connection and scope interface management, construction management and supervision, PAC (Provisional Acceptance Certification) review, operational asset management, and performance monitoring and fault diagnosis.

Working alongside developers, investors and finance providers alike, Green Cat has a thorough understanding of the key technical barriers to the successful delivery and operation of a solar PV site.


Generating power from a flow of water is a mature and very well established renewable technology. Green Cat has a wealth of experience in the delivery of high and low head run of river and storage hydro schemes, successfully delivering 25 hydropower projects in the 50kW to 2MW range.

Utilising our broad in-house capabilities and experience, we are able to offer the full range of expertise necessary to deliver a hydro project from inception, through feasibility, obtaining necessary consents, tender of civil, mechanical and electrical works, procurement of all components, to construction and completion.

Our services include:

  • Resource assessment.
  • All consenting works including all relevant abstraction licence applications.
  • Grid connection application, technical advice and management.
  • Civil and electrical engineering design.
  • Engineering construction management, including contract management, procurement, health and safety and construction supervision.
  • Due diligence and technical advisory services.
  • Operational asset management.


As intermittent generation continues to increase on the electricity system, the security of the electricity supply is becoming more of a prevalent issue for network operators on both a transmission and distribution scale. Implementing storage technologies onto the system have the advantage of being able to provide grid services. These include the participation in the capacity market and providing frequency response. There is also the opportunity to provide load shifting by charging the battery during the night from the grid when demand on the grid is lowest and the price is lowest, to then discharge during peak periods of demand.

Storage can be accommodated in locations with renewable generation (see Hybrid). Implementing this case can still provide the load shifting, to avoid peak tariffs, by storing self-generated renewable energy to then export to the grid at peak times. With the electricity network becoming increasingly constrained implementing storage schemes can optimise the use of a grid connection by providing a more stable output to the grid.

Our team of resource analysts and grid specialists are able to provide, design and optimise the storage installation to meet the requirements of the site and the local network.


Hybrid projects can significantly mitigate the issues around intermittency of renewables ensuring the output from the overall scheme is constant, reliable and renewable. The co-location of generation and storage technologies is a way of optimising an existing grid connection regardless of the constraints on local infrastructure. The inclusion of storage allows more generation to be implemented on a site compared to the grid capacity. Thus bypassing grid constraints reducing the costs of grid connections. Storage also allows for further grid services, such as load shifting, to be provided and hence provides further revenue streams for a project.

Combining renewables such as wind and solar, or combining renewables with storage or non-renewable generation provides a greater consistency of generation across the year and can level out the natural peaks and troughs of the generation profile when renewables are isolated. Implementing these schemes with onsite usage also have the potential to reduce your reliance on the grid. This in turn can have a positive effect on the users electricity bills.

EV deployment is expected to grow rapidly over the coming years, with the UK government planning to phase out sales of all vehicles that aren’t ULEV by 2040 (2032 in Scotland). In order to service the electrical demand required by these vehicles, a large number of charging points will be required at homes, workplaces and public locations. More and more charging stations are rapid charging (50kW) with High Power (100kW+) also seeing growth. The high power demands required by rapid and high power charging infrastructure will in many cases require expensive grid upgrades to accommodate their installation. In order to balance the strain placed on the grid network and avoid costly grid upgrades, there is an opportunity to co-locate renewable generation and battery storage alongside EV charging to minimise grid import costs.

Our team of resource analysts and grid specialists are able to provide detailed modelling to specify, design and optimise co-located generation to meet the requirements of the site.
