Energy efficiency & power quality consulting

We analyze your consumption data to find waste – reactive power charges, line losses, peak-hour loads – and deliver specific, measurable solutions.

Overview

Electricity is often one of a factory's largest production costs. Many items can be reduced without major investment: capacitor banks to avoid reactive power charges, phase balancing to reduce losses, and shifting loads to off-peak hours.

Because we manage the remote metering system, we already have your load data and can analyze it quickly and accurately.

Scope of service

  • Survey, load logging and power quality measurement
  • Design and installation of capacitor banks (fixed or automatic)
  • Harmonic assessment and filtering solutions
  • Phase balancing and loss reduction inside the factory
  • Advice on shifting loads to off-peak hours
  • Energy audit consulting on request

Benefits for your business

  • No more power factor penalties

    Raise the power factor to the required level and eliminate reactive power charges.

  • Lower losses

    Reduced current in cables and transformers means less energy wasted.

  • Optimized bills

    Re-schedule large equipment to reduce peak-hour consumption.

  • Longer equipment life

    Stable voltage and low harmonics keep motors and machines running smoothly.

  3. 3

    Solution proposal

    A report with investment cost, expected savings and payback period.

  4. 4

    Implementation

    Installation of capacitor banks, harmonic filters and system upgrades as approved.

  5. 5

    Measurement & verification

    Before-and-after comparison and a savings report.

Frequently asked questions

When must we pay for reactive power?
Under current regulations, customers whose power factor cos φ is below 0.9 must pay for reactive power. A suitable capacitor bank resolves this.
What is the payback period for a capacitor bank?
Usually very short if you are currently being charged for reactive power. The exact payback is calculated in the proposal report.
Do we need to stop production for the survey?
No. Logging equipment is installed while the factory runs normally to capture the real load.
How much does consulting cost?
Consulting is quoted according to the scale and scope of work. Please contact us for a preliminary consultation.
