Monitoring & Targeting Energy Management
Policy measure

The Ghana Energy Foundation has been promoting energy management and conservation measures in the industrial sector over the past years with the aim to create awareness of the benefits derived from good housekeeping and energy management practices, monitoring and targeting of energy and the savings achieved. An example of such efforts is the project Monitoring & Targeting Energy Management which was introduced to industries in Ghana in 1997. Through this project, energy consumption is monitored and compared with output (Energy Foundation, n.d.).

Implementation

According to the Energy Foundation (n.d.), the Tema Lube Oil Company (TLOC)., a producer of lubricating oils of various grades for use in vehicles and for mining and industrial applications, “is one of 10 companies where the Energy Foundation has implemented a pilot Monitoring and Targeting Energy Management Scheme to improve energy management. A total of US$7,034 was invested in purchasing and installing metering systems and equipment to improve power factor and training of technical staff in energy management.”


 “As part of TLOCs strategy to keep operating costs under control by utilizing production inputs efficiently, a formal energy management structure was put in place. The team monitors closely energy use pattern at the plant in relation to production output and makes recommendations for action to improve efficiency. To facilitate the energy management function, the company, with technical support from the Ministry of Mines & Energy and the Energy Foundation, installed an Energy Monitoring and Targeting (M&T) System to monitor and assist management to manage the energy resources available to the company. This involved the demarcation of the company into smaller Energy Account Centres (EAC). Separate energy meters were installed at each of the EACs. Weekly data on energy consumption and output for each individual EAC are collected and analyzed, using an” energy management software provided by the Ministry of Mines & Energy. The use of the software enables early detection of efficiency losses for prompt corrective action to be taken.” (Energy Foundation, n.d.)

Challenges
No identified challenges.
Outcomes

The following outcomes of the Monitoring and Targeting Energy Management efforts at TLOC  have been identified (Energy Foundation, n.d.):

  • “The Energy Management Team has achieved significant laudable success in the control of energy costs. By regularly monitoring their energy performance against set targets it was possible to identify cost effective measures to improve efficiency.

  • Some notable energy saving measures that were implemented include training of staff in Demand Side Management techniques, training in efficient boiler operations and the installation of a 200 kVAr capacitor bank which improved the factory’s power factor from 0.75 to 0.95. The company has also installed an electronic scale conditioner (scale blaster) recently on the boiler to minimize scaling and save on heating costs. These measures have resulted in a 35% reduction in the company’s electricity bills representing an annual cost savings of GHS 40 million.”
