A typical construction company had a long-term site for road bridge repairs that has just been extended to Phase 2. One of the major operating costs during Phase 1 was power generation for the onsite cabins and they want to understand where power is used, and what could be done to reduce costs. From a corporate perspective, they also want to reduce carbon usage, and diesel. For the site connection the Erica distribution was hard wired in, replacing the existing distribution panel, and configured to suit the current socket loadings.
The site was monitored for two periods, 1st August to the 31st of August and 16th January to the 31st of January, to build a picture of winter and summer use. Heating is a major consumer of power, so the effects of weather on usage was considered an important data set. This would help understanding of running costs during winter to determine if better insulation would help, and whether a smaller generator could be used during summer.
Erica by IDE is a power monitoring solution that has been developed to support onsite power management by recording usage across multiple connections on a continuous and long-term basis.
Recording power used, and storing this in the Cloud, an analysis can be carried out to identify:
> Where power may be wasted
> How to configure the site for lower usage
> Encourage good onsite discipline.
For this project IDE conducted two separate phases, one in January and one in August. This enabled a seasonal and daily analysis, to understand power needs over the long term.
The set up, on the right, shows the range of cabins.
The site is powered by a 100kVA generator set, which is connected through an Erica enabled site distribution panel, with monitoring on each connection.
For the site connection the Erica distribution was hard wired in, replacing the existing distribution panel, and configured to suit the current socket loadings. This was done out of hours, and the system was installed and running in a few hours. A 4G router was installed to access the Cloud so no access was required to the corporate IT system.
This is an important consideration to many companies in order to preserve security of their IT Systems. Live data is accessed through a simple web interface, again using no installed software.
Data collection was set to record results at 5 second intervals for each connection, which gives very good data analysis of power spikes as well as energy usage.
The dashboard, shown above, is a live feed from the distribution panel, helping the onsite team see the effects of turning power consuming equipment and facilities on and off.
