What is an Energy Management System and How It Works

Energy production largely relies on non-renewable energy sources such as coal, oil, and natural gas, which are also major contributors towards pollution and global warming. Industries engaged in manufacturing steel, cement, chemicals, etc are energy-intensive and have a large carbon footprint.

The year 2024 witnessed a 2.2% increase in global energy consumption, which was much faster than the historical trend of 1.5%/year between 2010-19. This contributed to an increase in greenhouse gas emissions, making 2024 the warmest year since global records began. The average surface temperature was recorded 2.23 degrees Fahrenheit above the pre-industrial average of 56.7 degrees Fahrenheit.

Given this trend, organizations have the responsibility to reduce their carbon footprints and greenhouse emissions by incorporating energy management systems. This would not only benefit the environment but also help you reduce your utility costs and increase operational efficiency.

With this article, we learn what an energy management system is, how it works, and the benefits that companies can achieve by implementing it.

What is an Energy Management System?

An energy management system (EnMS) is a structured framework designed around technical and managerial strategies. EnMS helps energy-consuming industries, businesses, and commercial and public sector organizations to manage their energy consumption and achieve their sustainability goals.

Energy management systems are based on ISO 50001:2018. They help you track your energy consumption and identify opportunities to cut energy costs, reduce your carbon footprint, and comply with environmental regulations.

How do Energy Management Systems Work?

As specified in the ISO 50001 standard, the working of an energy management system revolves around the plan-do-check-act framework.

1. Plan

The first step of an EnMS is to understand the context of the organization and conduct reviews to identify significant energy uses (SEUs). This would help you establish your organization’s objectives, energy targets, energy performance indicator (EnPI), energy baselines (EnB) and action plans to improve energy performance.

2. Do

In the Do stage, you implement an action plan to achieve your energy objectives. This would include making upgrades in heavy energy-consuming machinery, refining standard operational procedures, and regulating energy-intensive processes like lighting, HVAC, etc.

3. Check

Once you’ve identified key energy use cases in the organization and implemented measures to control them, you now have to monitor, analyse and evaluate your energy consumption against energy performance indicators, energy baselines and other objectives.

4. Act

Conduct reviews and generate reports on the energy consumption of the organization. Take corrective action for areas that do not meet energy objectives and show poor performance on EnPIs and EnBs.

Why do Companies Use Energy Management Systems?

Using an energy management system brings multiple benefits to companies in the form of cost savings, achieving sustainability goals and improving overall operations. The following points explain the benefits of an energy management system.

1. Reduced Costs

Energy markets have become increasingly volatile, with geopolitics and grid constraints affecting their pricing. These prices directly cut into your profit margins. By implementing EnMS, organizations can optimize their energy consumption by monitoring energy-intensive activities and implementing corrective actions to meet their energy targets.

2. Reduced Environmental Impact

How much energy you use directly affects your organization’s environmental impact. Large amounts of carbon footprints and greenhouse gas emissions damage your reputation among stakeholders and bring governmental scrutiny.

An energy management system helps you identify areas with high energy consumption and formulates mitigation plans to reduce waste, effectively helping you achieve your environmental, social and governance (ESG) and net zero goals.

3. Regulatory Compliance

Many countries govern energy consumption with stringent regulations that aim to reduce carbon emissions, achieve sustainability goals and expand renewable energy sectors.

Regulations like Streamlined Energy and Carbon Reporting (SECR) in the UK, Corporate Sustainability Reporting Directive (CSRD) in the EU, Energy Conservation Act in India, etc., mandate organizations to disclose their greenhouse emissions and achieve energy-saving targets. Non-compliance and failing to meet energy-saving targets often result in penalties.

Energy management systems allow your organization to monitor and measure your energy consumption against energy performance indicators and energy baselines. Instances of nonconformities or waste are reported to the management, who can implement corrective action plans.

4. Enhanced Stakeholder Trust

As the world is moving towards achieving sustainable development goals, all stakeholders expect companies to disclose information about the environmental impact of their activities, the working conditions of their employees and corporate ethics concerning their governance.

Implementing an energy management system in your organization serves as proof of your organization’s commitment to sustainable energy consumption and reducing operational risks, enhancing the trust of investors, lenders and insurers in you.

5. Operational Efficiency

Your profitability and productivity, both are impacted by how your organization manages energy. As energy production mostly relies on non-renewable sources, any shortage would affect the continuity of your business and disrupt operations.

This reflects the importance of implementing an energy management system, which helps you continually look for innovative ways to reduce your organization’s energy consumption while monitoring for key risk areas.

An effective way of achieving operational resilience would be to incorporate Effivity’s QHSE software that automates identifying and monitoring risks and opportunities, reduces waste and helps you accomplish environmental, social and governance (ESG) goals.

Common Challenges in Energy Management

1. Lack of Leadership Involvement

To successfully implement an energy management system in the organization, the leadership need to demonstrate their own commitment towards accomplishing energy saving targets and enhancing operational efficiency.

Formulating a dedicated energy management team or appointing a sustainable officer for monitoring and reviewing energy consumption is the first step towards implementing an energy management system.

2. Inadequate Energy Data Collection

To measure and monitor energy performance indicators and energy baselines, it is essential to have sufficient submeters and sensors employed in the organization. They are required to collect data on energy consumption. A lack of sensors and submeters would give rise to discrepancies in energy consumption analysis, hindering you from applying effective action plans.

3. Disjointed Systems

There are many regulations and requirements that a business has to fulfil before its product or service reaches the market. It needs to account for product quality, occupational health and safety, and the environment. In order to accomplish business objectives, energy management systems have to integrate with QHSE systems.

A disjointed system will affect your operational efficiency and ESG goals and make it difficult for you to identify risks and opportunities in your processes accurately.

Best Practices for Energy Management

1. Leadership Commitment

Bringing a change in an organization starts with leadership showing commitment towards the cause. To effectively implement an energy management system in the organization, leaders and management must engage with employees and help them understand their energy objectives and control measures to accomplish them.

2. Regular Audits

Risks and opportunities keep evolving the organization. A reactive approach to energy management often leads to significant wastage. That is why management should conduct regular audits to assess their processes, heavy machinery, HVAC, etc to identify risk areas with high energy consumption and opportunities to enhance their EMS.

3. Leverage Software

Instead of manually keeping track of your energy consumption, use Effivity’s integrated management system software that combines energy management with quality, health and safety, and environment management. It is equipped with modules to help you identify risks and opportunities in your organization and develop action plans to achieve your business and ESG goals.

Wrapping Up

An energy management system is becoming a necessity for every organization. It is not only needed to reduce their environmental impact, but also helps save on energy costs and increase their operational efficiency.

To reap the actual benefits of an energy management system, it should be combined with your organization’s QHSE system, such as Effivity’s Integrated Management System Software.
