Successful energy management

Abstract The file is a zipped PDF document.Experience shows that energy management is successful when the energy is managed like a resource, i.e. continuously, systematically, and in an organized manner, not like an expense (e.g. worrying about and paying the bills once a month). This requires the development and implementation of an energy management program (EMP).Following is a summary of guidelines for setting up a successful EMP, plant- or corporation-wide. The main driving forces of a successful EMP are: economic considerations and profitability; environmental consideration; and social considerations.Energy cost savings are direct profit, going straight to the ‘bottom line’ of the financial statement. For a plant operating with 5% profit margin, $100,000/yr energy savings means a profit equivalent to an increase of production and sales of $2,000,000/yr. In addition, there will be the corresponding reduction of greenhouse gas (GHG) emissions. The major barriers in developing and implementing a successful EMP include:

Energy is not visible (“out of sight, out of mind”)
Energy is not a core business, thus, there is a lack of interest and resources for it
Competition with other capital projects 
Energy may represent only a small part of the operating costs
Lack of knowledge in respect  to energy management
“Do nothing,” the biggest competitor

As a consequence, to be successful, the EMP must:

Include an energy monitoring, control, and reporting system
Be integrated into corporate plans
Be visibly supported by the executive management
Be led by an empowered energy manager
Specific manageable tasks be assigned to people 
Plant people participate in and are responsible for energy management

The development and implementation of a successful EMP almost always includes three key elements: executive management commitment; set-up of the energy management team; and development and implementation of the action plan. The efforts should be focused on setting-up the infrastructure and on execution.The infrastructure set-up includes:

Obtain visible commitment of the executive management
Obtain resources
Set up the energy management team.
Prepare the action plan for: energy analyses and training; and setting-up of communication channels, accountability, procedures, standards, and tools, energy usage monitoring, control, and reporting; etc

The execution includes: do the energy analyses; implement the selected energy management opportunities (EMOs); do the training; monitor and report; review and take corrective actions; publicize; and repeat.Energy management can be included in the engineering activity of consulting engineering companies. The development and implementation of managerial and engineering procedures for performing the engineering activity in respect to energy management ensures that whatever is being engineered includes viable energy management measures right from the beginning, when it is more cost effective to implement.The author developed and implemented this type of engineering approach in two reputable consulting engineering companies—Hatch and H.G. Engineering. The approach seems to gain recognition, as at least one government is following it up (i.e. “The Energy Efficient Design” method developed by the Danish Energy Agency in collaboration with the Danish Association of Consulting Engineers). According to the Danish program, companies that are developing new facilities or modernizing/expanding existing ones can use the services of an energy review team to optimize the design in respect to energy efficiency. Typical reported energy savings of projects following this approach are in the range of 15% to 30%, and even up to 50%. With the ratification of the Kyoto accord, perhaps the Canadian government should also consider this or a similar approach to help in meeting our substantial commitment in reducing the greenhouse gases emissions.

Summary: The file is a zipped PDF document.A survey of 281 mineral exploration agreements from 1988 to 1992 examines the ratios between the three ways to purchase an interest in a mineral property, viz. pay cash, pay shares, and make future expenditures on the property.The Northern Miner is used as the source to create a database for this study. Information about each agreement has been collected from volumes 74, 76, and 78 for the years 1988, 1990, and 1992, respectively. All agreements for which a...

Summary: The file is a zipped PDF document.The combination of a predictive reliability assessment model and discrete-event simulation can be an effective methodology to study the impact of equipment failures on the capacity of production systems in mines. In this study, a predictive reliability assessment model using genetic algorithms is combined with a discrete-event simulation model to analyze mine equipment systems.Discrete-event simulation studies the evolution of a system as variables change...

Summary: The file is a zipped PDF document.Thirty per cent of the electrical energy in Turkey is provided by coal-fired thermoelectric power plants. Five per cent of the demand is met by the Soma power plant’s six 165 MW generators. The plant is fed by lignite from open pit and underground mines in the Soma region that are operated by the government. With a nationalized mining policy in place, recently no investment has been made at these mines, as mining activity is generally considered by the...

Summary: The file is a zipped PDF document.No person can properly work without sufficient lighting and this is especially so in mines where conditions are difficult. Artificial lighting is very important for the night shift to provide a safe and efficient working environment. Haul roads within the pit are one of the critical areas in surface mines where lighting installations are not permanent due to regular advancement of the working face. The illumination design should fulfil the minimum lighting...
