ENERGY MANAGEMENT SYSTEM

 nEnMSsAn Energy Management Systems  (EnMS  ) is a methodology and systematic process for continually improving energy performance and maximizing energy savings and productivity by achieving the full cost-effective potential offered by energy efficiency. An EnMS establishes the structure and discipline to identify, develop and implement management and technical actions that significantly cut energy costs, minimize production downtimes, reduce greenhouse gas emissions and sustain savings and performance improvements achieved over time. By implementing an EnMS companies also optimize always their industrial systems and improve overall monitoring of system efficiencies.

A key focus and success factor of any EnMS implementation effort is the involvement of staff at all levels and functions of a company, starting from top management, and their continuous commitment to the EnMS and to improve energy performance. Continuous commitment and leadership of top management are critical in driving and ensuring on-going motivation of employees, which is a principal element of any effectively functioning EnMS.

Well-implemented EnMS introduce greater data due-diligence and energy analysis best-practices which enable companies to progressively improve their ability to monitor and forecast energy consumption, costs and CO2 emissions; to intervene in more timely manner when unexpected consumption occurs; and to better assess impact of specific measures and interventions implemented. Key benefits of Energy Management System implementation include: - Reduction and control of energy costs; - Improved energy assets management and material efficiency; - Increased productivity; - Reduction of GHG emissions and other environmental impacts; - Fulfilment of energy, environmental and other legal requirements (i.e. NEEAP, carbon emissions, etc.) - Greater energy security; - Enhanced social responsibility of organizations; - Design and procurement practices for energy-using equipment, systems, and processes; - Monitor and control all variables affecting energy performance.

Implementation experiences in many European countries, the USA and Japan have shown that:

  • Most industrial enterprises that fully implemented EnMS achieved average annual energy performance improvements of 2-3% against 1% of peer enterprises without EnMS ;
  • For companies new to energy management, savings during the first 2 years are usually in the 10-20% range with little or no capital investments.

The current international best-practice framework for implementing EnMS is represented by the international standard ISO 50001 Energy management systems – Requirements with guidance for use  , adopted as Moldova national standard SM ISO 50001:2012 Sisteme de management al energiei – Cerinte si ghid de utilizare.

ISO 50001 EnMS follow the same Plan-Do-Check-Act approach and structure of other well established international management systems such as Quality (e.g. ISO 9001) and Environment (e.g. ISO 14001) through a continuous cycle of making policyplanning actionsimplementing actions, checking results and reviewing progress, and updating policy and actions.

At the level of actual implementation, for an energy management system in line with ISO 50001 six steps to be highlighted are:

  •  Management commitment.  It requires company’s management to appoint and allocate sufficient staff resources to drive the EnMS implementation, develop energy policy and goals, assign roles and responsibilities, and mobilize employee;
  • Identification of significant energy uses. It requires the analysis of energy consumption flows (at least 80% of total consumption) to focus and prioritize energy conservation and performance improvement actions;
  • Define energy performance indicators. It requires thorough analysis to define appropriate indicators to effectively follow the evolution of energy consumption and performance in order to avoid inefficiency;
  • Identify opportunities.  It requires look for actions to save energy and improve energy efficiency of operations in a systematic and structured manner focusing on significant energy uses and then on no-cost and low-cost measures first;
  • Operational control.  It requires attention and interventions to optimally control operations of existing energy systems and production processes, which almost always operate well below the feasible and desirable efficiency level because of unnecessary and avoidable wastes;
  • Review EnMS and energy performance.  It requires periodic assessment and verification of EnMS implementation compliance and of progress with energy performance through regular checking, internal audit and/or external audit, and meetings with top management.

Within the scope and as result of the project "Reducing greenhouse gas emissions through  improved energy efficiency in the Industrial Sector in Moldova " implemented by the United Nations Industrial Development Organization (UNIDO) in collaboration with the Ministry of Environment and the Ministry of Economy of Moldova, and funded by the Global Environment Facility (GEF) a number of Moldovan companies and organizations have implemented energy management systems in line with ISO 50001:2011 (SM ISO 50001:2012) and achieved substantial economic and environmental benefits.  Companies include Lactis, JLC, CET-2, Termoservice, Apa-Canal, Municipal Urban Park Buses, Danube Logistics and the Orhei hospital.
