Wind Energy Powers Scottish NHS Community Hospital where 66% of energy comes from renewable sources
"The NPS 100 wind turbine generates renewable energy to offset the hospital's energy demand, reduces its carbon emissions and increases its energy efficiency. Our efforts to use more renewable energy on site is supported by the local community" - Alastair Kay, Energy Manager - NHS Ayrshire and Arran
WIND ENERGY POWERS SCOTTISH COMMUNITY HOSPITAL
Girvan Community Hospital
Girvan Community Hospital opened in 2010 and offers services such as minor injuries service, diagnostic facilities, a rehabilitation suite, 26 beds, elder-care day patient service and outpatient department plus has Scottish Ambulance on site. This vital multi-services hub needs a substantial, reliable, cost effective energy supply. The NPS 100 wind turbine makes this possible.

Commitment to an Environmentally-Healthy Hospital
Girvan Community Hospital opened in 2010 and was purposely built in an environmentally sustainable way. In addition to the NPS 100 wind turbine, the hospital also has a 700kw biomass boiler plant which burns wood pellets to produce additional energy. It also has equipment for collecting rainwater to use for flushing toilets. There were concerns that the wind turbine could damage the local bat population. During the planning process for the wind turbine, the Royal Society for the Protection of Birds (RSPB) was consulted about this concern. An in-depth environmental impact assessment, incorporating an ecology study was carried out, and RSPB reported that impact on bats would be negligible. The resulting landscape plan has a planting design that not only attracts bats away from the wind turbine, but also benefits other existing wildlife. 66% of Girvan Community Hospital’s energy comes for renewable sources. The NPS 100 wind turbine produces high annual energy production (AEP). It is estimated that the turbine at the Girvan site produces an average of 236,000 kWh per annum. With the electricity rate set at 11p per kWh, the NPS 100 generates significant savings for the community hospital. This allows Girvan Community Hospital management to increase investments into additional medical facilities and expand services offered at the hospital. Another advantage of NPS 100 is its core patented technology – Permanent Magnet Direct Drive (PMDD). It has fewer moving parts than traditional gear box wind turbines, which translates into higher availability time and less maintenance costs over time. On average, NPS 100 wind turbines require service only once a year. Once installed and commissioned in 2010, the NPS 100 began generating electricity for the Girvan Community Hospitals even on low-wind days. With cut-in wind speeds as low as 3m/s, the wind turbine generates electricity for the hospital to be consumed onsite. Qualified as a low wind site (5m/s at hub height), the project is on course to pay itself off within 6.3 years.
In addition to offsetting the hospital’s energy supply and saving on electricity purchase costs, Girvan Community Hospital will continue to enjoy stable energy supply for years to come. By generating energy from no-cost wind, power expenditure will be stable for the 20+ year lifetime of the turbine and protect the hospital from volatile and ever-escalating power costs.
RELIABLE, PROVEN TECHNOLOGY
The wind turbine’s gearless design with PMDD core technology ensures low maintenance operation. The NPS 100 is built with reliability in mind, so that turbine owners can focus on what’s really important to them. For Girvan Community Hospital that’s healthcare, including diagnostics and rehabilitation services.
The investment in renewable technology is an example of how seriously the NHS and the Girvan community take their commitment to the environment, and to using sustainable resources. In addition to supplying clean, renewable energy, the NPS 100 wind turbine offsets 135 tons of CO2 per year.
