Agriculture Case Studies

Solar Case Example

Farmsteads are ideal for solar installations with large roof areas available and high energy usage on site during daylight hours.

Main Source of high energy usage: Lighting, refrigeration, milking.

Size:
150 KWp equal to 2,400 m2 or 25,800 sq ft.
Cost of the System:
£195,000
Forecast Output:
130,500 KWh per annum
Usage on site:
100%
CO2 emissions saved:
60 tonnes per annum which is equal to 6 average UK households
Savings:
Assuming all energy is used on site, a 50% reduction on energy costs per KWh would save £222,086 over 20 years (based on 2.5% RPI)

Wind Case Example

With many farmsteads now looking to supplement income, a wind turbine is an ideal source of additional revenue for the next 20 years and beyond. A major advantage is the small amount of land required to generate this income allowing the farm to continue working the land.

Size:
250kWp
Cost of the System:
£429,500 (estimate)
Forecast Output:
558,749 kWp/annum
Usage on site:
0% used on site
CO2 emissions saved:
223 tonnes P/A is equal to 22 average UK households
Savings:
£7,450 PA (increasing annual by circa 2.5% for 20 years)

Blackmore Farm - solar

Blackmore Farm, a large arable farm in Lincolnshire, consumes a significant amount of electricity running refrigeration equipment and grain dryers, particularly over the harvest season. The 150kWp solar PV system, installed for the tenant farmer provides a huge saving on green electricity and makes a great source of income for the owner. The Solar PV system meets approximately 20% of the total annual site demand.

Once they fully understood our business, our electricity usage and what we were looking to achieve from installing the PV, they set about designing a range of suitable options for us to consider.

“Right from our initial contact with the team, we were impressed with the knowledgeable, open and transparent way they worked with us.”
Mr Bartlett, Owner Blackmore Farm

South Brent - wind

The people of South Brent raised over £380,000 to purchase the wind turbine by buying shares in the wind turbine itself. The turbine is expected to generate over 400,000 kWh per year which is 100 homes worth of electricity and save approximately 200 tonnes of CO2 from the burning of fossil fuels in power stations each year. The V27 was installed and commissioned by spectrums highly skilled wind engineers.

Throughout the community wind project, Spectrum operated as technical support, negotiated with the national grid, submitted planning documents, conducted both soil and structural surveys, design and project management services, provided full insurance, and officially signed off the V27 wind turbine, which ultimately gave South Brent Community Energy Society the peace of mind that everything had been taken care of.
Having renewable systems running at optimum capacity is essential for a profitable project. It is also crucial to have qualified service technicians and parts available when needed. Operation and maintenance maximise the return from a turbine throughout its entire lifespan. Spectrum provided a full O&M package including insurance and loss of earnings protection, giving complete peace of mind.

Director of South Brent Community Energy Society, “The South Brent Community Energy Society project has raised well in excess of the £420,000 target, pulling in £430,000 through a community share issue. We now have almost 200 members, consisting of 68% South Brent residents and 26% from surrounding areas.
The proceeds from the scheme will be divided equally between private investors and public benefit schemes. All proceeds will be ploughed back into the community”.
