Large Naval Base with attached dockyard. Base has multiple legacy buildings and large quantities of relatively inefficient industrial machinery. In 2007, electricity usage amounted to over a half million euros. Quite apart from price rises, this was set to increase by 20% in 2008.
In September 2007, ResourceKraft metering systems were installed by contracted electricians on 10 separate three-phase sub circuits and 2 main incomers at two separate substations within the complex. The main incomers were rated at 1000amps per phase, while the sub circuits were rated at between 100 and 600 amps per phase. The installation took a total of 1.5 person days and only involved 30 minutes of down time during installation on uninsulated busbars.
For the first time, it was clearly understood what was being used on the large sub circuits. It was discovered that 10% of the users were consuming in the region of 90% of the electricity. Where as previously the customer could only see overall usage once a month on two utility bills, he could now see clearly:
- When the Electricity was being used
- Where it was being used
- How it was being used
€13,000 inclusive of equipment, installation and first years subscription
The major savings were in the reduction of the electricity utility bills, which as of early 2008 were set to reduce by 30%. Another major impact was that the increased understanding of where and when electricity was being used meant that the utilisation of the substations could be more closely monitored. It had been perceived for some time that the bases substations were at risk of becoming overloaded as major loads were added without warning. With the information provided by ResourceKraft Advisor, it became possible to institute load management procedures to prevent major outages, whilst also identifying the need to upgrade the substation infrastructure.
