Our geology and geomorphology services helped mitigate challenging terrain for a wind farm in an isolated part of Ireland servicing 70,000 rural households with clean energy
Location: Co Kerry
Client: ESBI
Country: Ireland
Start Date: 2018
End Date: 2019
Capital Cost: €180m (estimated)
Grousemount Wind Farm is being developed by Kerry Wind Power Ltd, a wholly owned subsidiary of ESB. The site is located in south east Kerry, between the villages of Kilgarvan and Coolea in Co Cork. The project for 38No. Wind Turbines was granted permission from An Bord Pleanála in Summer 2016. Grousemount Wind Farm began construction in 2018 and includes approximately 23km of access roads. The delivery and installation of 38 wind turbines, with a combined generating capacity of 114 Megawatts (MW) will meet the electricity needs of around 70,000 households. The Grousemount Wind Farm Community Benefit Fund (the “Fund”) will provide €145,605 each year to the wind farm community for the life time of the Wind Farm which is expected to be 25 years.
Ayesa were employed by ESBI to carry out geomorphology and geological surveys and to assess the Wind Farm Detailed Geotechnical Design and advise on any changes required to mitigate the risk of rock slope instability. We developed solutions for problematic areas such as deep rock cuts and hardstand areas with rock stability concerns and introduced geosynthetic reinforcement for hardstand fill areas on steeply sloping ground.
Supporting Construction and Design and Build
Halsary is one of two onshore wind farms being constructed in Scotland under ScottishPower Renewables’ portfolio and has achieved its first export on schedule before the end of 2020. Fifteen turbines are being installed at the site, with six currently energised and connected to the grid. Halsary generates around 30MW of renewable electricity – powering the equivalent of more than 20,000 homes. The 30MW development also helps power Tesco stores and operations across the UK, bringing more clean energy to the grid.
Ayesa was commissioned by Farrans to undertake the detailed structural design of gravity foundations and control building. The control building was a steel portal frame structure with shallow spread foundations, masonry walls and a ground bearing slab. A single storey basement with a suspended GRP access floor is provided over part of the footprint. Building design was coordinated with incoming services to receive the electrical output from the turbines. Design of turbine foundations & control building included full detailed design deliverables (GA drgs, sections, specification info & RC drgs and bending schedules). The turbine foundation design was Cat3 checked by an independent company to achieve technical approval. The Control Building design was reviewed by an independent engineer to achieve Building Control (Scotland) sign-off. We worked closely with both parties to gain the necessary approvals.

Solving drainage problems in a hilly site and providing value engineering to mimimise costs
provided designs for crane hardstands and access tracks, including optimisation and value engineering of the client’s tender package along with SuDS & drainage design for this difficult, hilly site.
The project/works consisted of the civils design of the crane hardstands and access tracks, including optimisation and value engineering of the tender design package and SuDS & Drainage Design for this challenging, hilly site. It also included design of four culvert crossings and associated bridge structures, civils design associated with Substation Platform, Civils Design of Public Road Upgrade Works for turbine delivery (TDR) and finally, Structural Design of 19 WTG bases.
Ayesa undertook site inspections, sign offs and approvals of turbine base formation level, finished hardstand and access track surface. This project was constructed by a local contractor, but promoted by the major Italian Energy utility provider, ERG.

Glenconway wind farm in Northern Ireland was developed by SSE Renewables and constructed by Gael Force Renewables Ltd, a joint venture between McLaughlin & Harvey, Barr and W&H Alexander. The 20 turbine, 46MW site near Limavady forms part of SSE’s Slieve Kirk Wind Park and is Northern Ireland’s first and largest grouped wind farm development. Phase 2 comprised a 12 turbine extension of 2.3MW Siemens wind turbines.
Ayesa was appointed by Gael Force Renewables Ltd as the civil designer for the Phase 2 development. The design required a flexible approach to allow for the presence of deep peat across the site and the need to allow for commercial harvesting of the peat upon completion of the works.
We prepared the civils design package including 5.5km of internal access roads, which run through challenging deep peat areas. Our team also worked on the geotechnical and structural design of piled and gravity turbine bases.
A dedicated team of multidisciplinary engineers were assigned to ensure this project was completed on time and within budget

Altamuskin Wind Farm in County Tyrone comprises six 2.3MW Enercon E-82 wind turbines, along with 1.4km of upgraded and new access tracks. AYESA acted as civil and geotechnical consultants on the project, which included design and supervision of the entire infrastructure works.
The works included civils design of crane hardstands and access tracks, drainage design (including SuDS) for the complete site, cable routes and utility trench details, civils design of public road upgrade works, the Transportation Delivery Route for the turbines along with substation design. Ayesa also undertook site inspections, sign-offs and approvals of turbine base formation level, finished hardstand and access track surface. Throughout the design process and the construction phase, a dedicated team of civil, geotechnical & structural engineers was assigned to the project.
Reducing the embodied carbon and costs through classification and reuse of site materials
The new extension of the Aikengall “Phase II” wind farm, south of Dunbar in east Scotland consisted of 19 Siemens Direct Drive wind turbine machines with an installed capacity of 48MW to create clean, green electricity. The wind farm forms an extension of Community Windpower’s operational Aikengall Community Wind Farm. The wind farm comprises of 16 Vestas V90 wind turbines. These wind turbines have a tip height of 125 metres and each has a generating capacity of 3MW. Many of the turbines were situated on high ridges in difficult and remote terrain. These wind turbines have a tip height of 125 metres and a generating capacity of 3MW, delivering energy to over 31,000 households displacing around 54,200 tonnes of Carbon Dioxide per annum.
Ayesa, acting as civil and geotechnical consultants on the project, was appointed to design and supervise the ground investigation works; produce the civils package for access tracks (10 km long), culverts and river crossings, and design crane hardstand areas to facilitate erection of wind turbine towers. Ayesa determined the suitability and classification of site-won material to maximise the volume of site material for reuse as road stone, and to limit export of excavation arisings off site.
Ayesa value engineered the number and length of access roads required by initial planning proposal by rationalising accesses and reducing the total required length of road required at construction stage by approximately 15%, which provided significant savings to the contractor and developer. facilitate erection of wind turbine towers.
