CPSL Group were approached by a distillery in Scotland who wanted to become as ‘Green’ as possible and control their energy costs as much as possible in a holistic manner. This was a perfect fit with the CPSL Holistic approach to renewable energy, as we are firmly of the opinion that it is a complete circle, of producing the right amount of power for the site and matching demand to supply and vice versa.

 

In this on-going project we first analysed their energy usage and found that they were making enough power from their renewable resources in the course of the year but most of it was being produced at the wrong time and in the wrong amount.

 

This was a perfect example of how energy storage could help give a holistic approach to the problem and match the supply and demand together. A further problem to the energy supply was that there was an export limit on the site. This meant that the renewable energy generators were being switched on and off at times of high and over production. This was leading to stress on the system and for the generators to wear out. This was solved by being able to ramp the power control and divert part of the power to storage so as not to place a strain on the Grid network or the onsite network.

 

They already had an 11 kW wind turbine and 15 kW of solar panels. The power however was often produced at the wrong time and in the wrong amount. Energy storage was the answer and the installation of a CPSL Bio power Combined Heat and Power system could also supply additional power and heat that was required for the distilling process. A further desire was to use Hydrogen as a vehicle fuel to run the delivery vehicles for the company in order to enhance their ‘Green; credentials.

 

The distillery had no energy monitoring on site and so they had no idea of what they were producing or where they were using it. Also, if any part of the plant had a problem, they were unaware until it broke down. Our monitoring system allowed every circuit on the site to be monitored every 6 seconds and if any problems occurred or demand on a particular circuit increased, it was instantly noticed and appropriate action could be taken. This enabled payback times to be reduced and repair costs minimised. The payback time for installing the monitoring equipment was estimated at 2 years.

 

They also wanted to be able to run their vehicles from renewable energy. They already had an electric vehicle and plans were made to purchase electric vehicles with Hydrogen range extenders and for the excess power on the site to be converted into hydrogen and for the amount of Hydrogen production to be increased as the number of Hydrogen powered vehicles increases.
