Energy Intensity Reduction

Managing energy related costs as a share of the total operating cost is a key challenge for the mining industry in the current complex and rapidly evolving landscape. We’re here to partner with you to reduce your costs and boost productivity through Hitachi’s innovative and non-intrusive energy management software solutions.

Key Energy Challenges for the Mining Industry

Energy related costs are increasing as a share of the total operating cost of a mine, due to:

  • Deeper mines
  • Increasing remoteness of operations
  • Rising energy prices
  • Changing energy source make up
  • Ventilation for underground mines
  • Potential carbon pricing effects


The benefits of Hitachi’s Energy Intensity Reduction system:

  • OPEX reduction
  • Deferment of CAPEX for energy related assets
  • Reduction in energy = a reduction in run-hours

Energy Visualisation Dashboard

What is EVD?

Non-intrusive energy management software used to project total energy consumption and production throughput in dashboard form.

Why use EVD?

For a small investment, it will enable consumers to identify:

  • Areas of wastage
  • Facilities that have poor energy efficiency
  • Correlation between energy usage and productivity.

The Dashboard will:

  • Build awareness of energy costs, usage and efficiency
  • Drive behavioural change and process improvements
  • Report on organisation performance

Energy Intensity Analysis and Optimisation

Overall Electricity Energy efficiency and stability can be improved by utilising Hitachi’s technology, operation, as well as maintenance and planning expertise – covering both supply and demand side.

EVD Key Features

Estimating energy saving

  • Calculating machine efficiency
  • Categorising machine items

Visualising and Comparing

  • With each hour, day, week and;
  • With different duration, machine, process, site e.g. user can grasp each machine condition

The Dashboard will:

  • Share energy saving activity
  • Allow user to search earlier activity on energy saving
  • Identify wastage points
  • Estimate energy saving opportunities
  • Share successful knowledge to overall site

EVD Screens

  • Overview Screen
  • Performance screen
  • Insights screen

Case Studies

Energy Management in Hitachi Group

Energy Management in Hitachi Group

Hitachi leads by example in energy management, and thanks to the deployment of an internal Energy Management System (EMS) over 238 major sites globally, we have reduced Hitachi Group’s energy consumption by 19% and streamlined our own management and production processes.

Hakkan Industrial Complex

Hakkan Industrial Complex

As part of an energy saving promotion in 2013 for the Hakkan Industrial Complex in Sapporo city in Japan, Hitachi provided an Energy Visualisation Dashboard as the first implementation step. This allowed the organisation to visualise and analyse the energy data of its electricity use, and make informed decisions on areas to allow energy savings, reduce costs and introduce continuous energy saving improvements.
