Mr. Douglas Shand, Hilton Park Farm, Banff, Aberdeenshire

Intelligent Hands Off Heatpump Systems

The Introduction.

Mr Douglas Shand owns an arable farm near Banff in Aberdeenshire, in 2014 Mr. Shand installed his first commercial Ground Source Heatpump. This successful project paved the way for a much larger scale renewable project, to tie into his 100kW wind turbine. In 2018 Mr. Shand engaged Calibrate again to install a 499kW Ground Source Heatpump system that supplies heating to dry grain, grass and logs as well as a new hydroponics system and hydrotherapy pool. A Bespoke Control System remotely manages all of the renewable technologies. This enables Mr. Shand to have a ‘hands off’ approach as well as enabling real time tariff generation and power consumption readings. The export management function of this controller enables the variable speed Heatpump to suit the 100kw existing wind turbine, this reduces the import power and therefore, running costs. The system is currently running at 380% efficiency.

The Figures.

The Heatpump system has 4 year pay back; a 549% return on investment and will generate Mr. Shand £907,221* over the 20 year Government Tariff.

The Conclusion.

The systems were installed in under 3 months during the  day to day operation of the farm with no downtime required. Currently the export management system has the heatpump using only the excess generated power further decreasing costs and the payback period.

Demand Side Response (DSR)

DSR financially incentivises energy users to increase or reduce on demand nonessential energy usage at times of peak or low demand.

Why is demand response needed?

The National Grid has to maintain a certain level of energy production capacity above actual demand. DSR is designed to provide the margin, either by increasing or decreasing site energy use.

What are the benefits of demand side response to you?

The primary business arguments for DSR are financial renumeration and sustainability. DSR not only allows businesses to avoid higher energy prices and receive renumeration during times on and off peak demand.
