Introduction

ISO 50001 is capable of establishing an energy management system for a single organization to promote continuous improvement in energy performance. In some cases, several Organizations that collaborate on energy management by forming an Energy Management Alliance (EnMG) typically achieve better results.

This situation may be caused by technological changes and the popularization of distributed energy.

An energy management alliance may include the following organizations.

---Operating within the same geographical area, such as a city, administrative region, or industrial park;

---Being in the same industry, such as food processing, railway transportation, or higher education;

---Having common customers (supply chain members), such as supermarket supply chains or automobile manufacturers;

---Those who share the same service providers, such as building owners located in the same shopping mall;

---Shared utility facilities (steam, electricity, etc.);

---A department that forms a franchise group, which may (but is not required to) have shared suppliers, such as franchised fast food chains.

(With shared suppliers), or independent retail stores operating under the cooperative;

---forming part of a broader economic group with financial ties or common ownership;

---All different types of facilities of the municipal government (such as government offices, libraries, hospitals, etc.);

---Sharing a common goal or energy objective (voluntary or mandatory);

---Agree to improve the same Energy Performance Index (EnPI);

---Members of the same trade association.

The methods described in this document are also applicable to multi-site organizations with a single or shared management system.

By combining or sharing energy management methods among multiple organizations, an organizational group can obtain energy management benefits that a single organization could not achieve.

Furthermore, by focusing on the energy flowing through each organizational boundary, new energy-saving opportunities can be identified. These opportunities are difficult to discover within a single organization.

In general, wider boundaries lead to more opportunities for energy performance improvement and more significant energy performance improvements.

The establishment of joint energy management organizations driven by shared energy demand aims to create synergies or share expertise to improve energy efficiency.

Performance.

Example 1.Large investments in energy efficiency can lead to greater efficiency (one large boiler instead of several small boilers).

Example 2.Sharing waste heat or local renewable energy supply.

Having at least one member in the organization with experience in energy management systems will greatly help the team implement them.

This document provides guidelines for establishing shared energy management based on ISO 50001, but focuses on the coordinated efforts of multiple organizations in energy management.

Problems that arise during management. The existence of multiple organizations necessitates guidance on the management of shared energy management systems, such as.

---The role of leaders;

---plan;

---Support for shared or joint operations;

---Shared or joint operations or execution;

---Knowledge transfer;

---Best Practice Sharing;

---Performance evaluation;

---Confirm continuous improvement.

An additional benefit of a shared energy management system is the ability to share experience, equipment, and other resources within the organization, thereby reducing costs and promoting system improvement.

Example 3.In the mining or agricultural sector alone, it is costly to introduce expertise (such as pump specialists to reduce energy consumption in agricultural irrigation) or hire professional mechanics.

Energy management consortia are typically able to share the costs of expert services, travel, and accommodation.
