Energy Management Information Systems (EMIS): Turning Energy Data into Cost and Carbon Savings

Energy is a significant operating cost for many organizations, but knowing how much energy a facility consumes is not the same as knowing how effectively that energy is being used.

Utility bills tell an organization what it consumed and what it paid. They do not necessarily reveal where energy is being wasted, why consumption increased, whether equipment is performing as expected, or what actions should be prioritized.

An Energy Management Information System (EMIS) can help close this gap by transforming energy and operational data into information that organizations can use to improve performance, control costs and support emissions-reduction objectives.

What is an EMIS?

Natural Resources Canada (NRCan) describes an EMIS as a performance management system that enables organizations to plan, make decisions and take effective action to manage energy use and costs. It converts energy data and relevant operational information into energy performance information that can be used throughout an organization.

An EMIS is therefore more than energy-monitoring software or a dashboard.

A well-designed system brings together metering, data collection, system integration, analysis, reporting, people and management procedures. The objective is not simply to collect more data—it is to make energy performance visible and actionable.

For example, a facility may know from its monthly bill that electricity consumption increased by 10%. An effective EMIS can help the organization investigate what changed. Was production higher? Did equipment operate for longer hours? Did an HVAC system begin consuming more energy than expected? Was there an unusual overnight load?

The value comes from moving from “How much energy did we use?” to “Why did we use it, and what can we do about it?”

From Data to Decisions

Many facilities already generate substantial amounts of information through utility meters, submeters, building automation systems, production systems and equipment controls. The challenge is turning these separate data sources into meaningful information.

NRCan’s EMIS framework describes a system that incorporates energy account centres, metering and inputs, data capture and integration, data analysis and reporting, and the people and procedures needed to manage performance.

This creates a continuous improvement cycle:

Measure → Analyze → Identify → Act → Verify → Improve

Rather than waiting for a monthly utility bill to reveal that something has changed, organizations can use appropriately configured energy information to detect performance issues much earlier.

That visibility can change the way energy is managed.

Where Can the Savings Come From?

Not every energy-saving opportunity requires replacing equipment.

Consider a manufacturing facility where a compressed-air system continues operating at full pressure during periods of low production. Or a commercial facility where heating and cooling systems operate outside normal occupancy hours.

Without detailed information, these conditions can continue unnoticed.

An EMIS can help organizations identify patterns such as unusually high baseloads, unexpected consumption during shutdown periods, changes in equipment performance, abnormal peak demand and differences between expected and actual energy consumption.

These insights allow facility and operations teams to investigate causes and determine appropriate corrective actions.

NRCan’s EMIS handbook indicates that a well-designed EMIS should support sustained reductions in energy use and cost and identifies a 5% reduction as an expected benchmark for a good EMIS. Actual savings, however, will depend on the facility, existing energy-management maturity, identified opportunities and the actions taken in response to the information generated.

Connecting Energy Savings and Carbon Reduction

The relationship between energy management and greenhouse gas emissions is increasingly important.

Energy consumption can contribute directly to an organization’s emissions through fuels burned onsite and indirectly through purchased electricity. Reducing unnecessary energy consumption can therefore contribute to both operating-cost reductions and emissions-reduction strategies.

This makes EMIS relevant beyond the facilities or engineering department.

Reliable energy-performance information can also support GHG inventories, energy and emissions baselines, sustainability reporting, decarbonization planning and progress toward organizational climate targets.

The connection is straightforward:

Better data → better energy decisions → lower unnecessary energy consumption → lower costs and potentially lower GHG emissions.

NRCan similarly identifies energy management as a means of improving energy efficiency, productivity and competitiveness while supporting energy, cost and GHG emissions reductions. Natural Resources Canada

EMIS and ISO 50001

Organizations considering a more structured approach to energy management may also find EMIS valuable in supporting an energy management system such as ISO 50001.

ISO 50001 provides a framework for systematically managing energy performance. It emphasizes elements such as energy reviews, baselines, energy performance indicators, objectives, action plans, monitoring and continual improvement.

An EMIS can provide much of the information infrastructure needed to support these activities.

NRCan notes that ISO 50001 integrates energy efficiency into management practices, improves awareness of energy use and helps organizations prioritize energy-efficient technologies and improvements.

An organization does not necessarily need to pursue ISO 50001 certification to benefit from these principles. The important shift is treating energy as something that is actively managed rather than simply purchased and paid for.

Building an EMIS: Start With the Organization, Not the Software

One of the most important decisions when implementing an EMIS is determining what the organization actually needs before selecting technology.

NRCan structures EMIS development into three broad phases: an EMIS Audit, development of an Implementation Plan, and Implementation. The initial audit examines areas including energy account centres, metering, data capture and integration, analysis and reporting, and management systems involving people and procedures.

A practical starting point is therefore to ask:

• What are our significant energy uses?
• What energy data do we currently collect?
• Where are our meters and submeters?
• What operational variables affect consumption?
• Which equipment or processes should be monitored?
• What energy performance indicators would be meaningful?
• Who needs the information?
• How frequently is the information required?
• What decisions will be made using the data?
• Who will be responsible for acting when performance deviates from expectations?

Only after these questions are understood should the organization determine the appropriate metering, software, dashboards, analytics and system integrations.

A sophisticated platform with poorly defined objectives can produce enormous quantities of data without producing meaningful energy savings.

Ontario Facilities Have a Timely Funding Opportunity

For qualifying Ontario industrial facilities, the business case for EMIS may currently be particularly attractive.

The Save on Energy Expanded Energy Management Program provides financial support for industrial EMIS projects. Industrial facilities with annual baseline energy consumption of 400,000 GJ or less may be eligible for up to $50,000, while facilities consuming more than 400,000 GJ may be eligible for up to $250,000, subject to a maximum of 50% of eligible project costs.

The program states that eligible facilities must be located in Ontario and connected to the IESO-controlled grid or a distribution system, with additional eligibility requirements applying. Financial support for industrial facilities is provided by NRCan through its Green Industrial Facilities and Manufacturing Program.

Importantly, organizations considering the incentive should investigate eligibility before committing to an EMIS project. Save on Energy states that a Retrofit application must be submitted before incurring or entering into a financially binding commitment for the EMIS project, and projects started before pre-approval may not receive the anticipated incentive.

This makes early planning particularly important.

A Practical Path Forward

Organizations do not need to begin by purchasing a large technology platform.

The first step should be understanding current energy performance and determining whether an EMIS has a strong operational and financial case.

An organization can begin by assessing its existing energy data, metering infrastructure, significant energy uses, operational systems and energy-management practices. From there, gaps can be identified and an EMIS designed around the organization’s actual needs.

For some facilities, the priority may be additional submetering. For others, the greatest opportunity may lie in integrating existing data that is currently stored in separate systems. Some organizations may already have substantial monitoring capabilities but need better analytics, performance indicators, reporting procedures or accountability for acting on the information.

The right EMIS should therefore reflect the facility—not the other way around.

Turning Information Into Performance

Digital technology is making it increasingly possible for organizations to understand their energy performance in greater detail. But technology alone does not save energy.

People save energy by making better decisions and taking better actions.

The role of an EMIS is to provide them with the information needed to do so.

When energy information is timely, relevant and connected to operational decision-making, organizations can move beyond simply paying energy bills toward actively managing energy performance.

That can translate into lower operating costs, improved equipment performance, stronger energy-management practices and measurable progress toward carbon-reduction objectives.

For organizations facing increasing pressure to improve efficiency while reducing emissions, the question may no longer be simply, “How much energy are we using?”

A more valuable question is:

“What is our energy data telling us—and what are we going to do with it?”
