PowaTrim cuts energy use and emissions with Envisij
PowaTrim used Envisij to tackle high energy costs and voltage issues at a large industrial site. The result: lower bills, fewer emissions and kit that lasts longer.

The challenge
What PowaTrim needed to solve
- A single local transformer powered a large industrial site, and voltage swings were burning out motors.
- The team needed real-time three phase and single phase voltage, power factor and kW readings.
- Engineering offices 200 miles away needed remote access and history to spot trends.
- Any efficiency work had to be verifiable so facilities and finance teams could sign off future investment.
Background
About PowaTrim
PowaTrim Ltd supplies power quality products and services to industrial and commercial sites, helping them run more efficiently and cut consumption. One client, a large industrial campus, was seeing frequent motor failures caused by high, fluctuating voltage from their 11kV to 400V transformer.
The solution
How Envisij helped
- Envisij was installed at the site's main incoming supply to stream real-time data to the cloud.
- Half-hourly meter data was pulled in automatically each day for savings verification.
- Live and historical power data appeared side by side in the Envisij dashboard.
- The facilities team got clear, shareable views of voltage, power factor and kWh.
The outcome
What changed
Envisij's data showed three phase voltage averaging around 430V, well above the 400V sweet spot. PowaTrim worked with the local Distribution Network Operator to tap the transformer down. The switch happened over a weekend and the benefits were immediate. The facilities team have since committed to using Envisij to track four more efficiency projects a year on the road to a 30% cut in energy use over three years.
“Working with Envisij has been seamless. Their expertise in energy monitoring and analytics has given us insights that let our team drive real efficiency gains for clients with confidence.”
