How Microgrid Power Efficiency Is Transforming Energy Costs and Reliability for Commercial & Industrial Users

Grid inefficiencies result in significant costs for businesses each year. 

According to the U.S. Energy Information Administration (EIA), about 5% of the energy generated in the U.S. is wasted due to transmission and distribution (T&D) losses. 

At the same time, demand from energy-intensive industries such as data centers and manufacturing facilities and the increasing prevalence of renewable energy are placing more strain on the grid, making power outages more likely. Demand for electricity in the U.S. is projected to grow by as much as 15% by 2050. Rising demand coupled with grid inefficiencies and vulnerabilities results in higher rates and peak demand charges for businesses and consumers. 

Fortunately, there’s good news — improving power efficiency can help businesses save on energy costs. Here’s how. 

Understanding Power Efficiency: It’s About More Than Saving Energy

When most people hear “power efficiency,” they think of energy-saving actions such as purchasing energy-efficient appliances and turning off the lights when they leave a room. But power efficiency encompasses more than that. Here are a few key terms:

• Apparent power is the total power supplied to a system, including power that does work and power that oscillates due to reactive components such as transformers, motors, and fluorescent lights.
  
  
• Actual power is the power that’s converted into useful work, like lighting a bulb, heating a space, or turning gears on a motor.
  
  
• Power factor is the ratio of actual power to apparent power, showing how efficiently electrical power is used. If the power factor is 1 (or 100%), all power is used effectively. A lower power factor reflects poor efficiency—in other words, some power has been lost.

• Load factor is the ratio of the average load over time to the maximum or peak load during that same period. This formula measures the consistency of power usage over time. A load factor at or close to 100% means steady and efficient power usage, while a low load factor shows that peak demand exceeds average use.

When your business operates with a low power factor, utility bills increase. Those added costs can be due to demand charges based on peak usage. Even if you’re not using any more actual power, your peak demand will appear higher because you’re consuming more apparent power.  Other utility bill surprises could include the fees some utilities charge if the power factor drops below a certain level. 

Operating with a poor load factor also yields unwelcome financial consequences. You’re using your peak capacity only occasionally, which means power use is inefficient, and you’re paying for infrastructure that isn’t used most of the time. Your utility company might also price its services to reward predictable use, also known as a high load factor. If that’s the case, your poor load factor will trigger higher unit prices per kilowatt hour, even if your total energy consumption doesn’t increase.

Transient Loads and Peak Demand: The Invisible Energy Burden

Many commercial and industrial facilities have volatile energy needs. They might experience voltage spikes during motor startups, equipment cycling, or digital load bursts. They often operate on shifts and produce products in batches, so they could have periods of high demand followed by little to no power demand. These fluctuations in power, also known as transient loads, create unpredictable utility costs due to demand charges.

Data centers pose a different power demand problem. They tend to have always-on loads that rapidly increase as computing needs grow, requiring more processing power. At the same time, data centers must run constant cooling systems to keep hardware from overheating. These cooling systems also need a significant amount of power to operate, especially when outdoor temperatures rise in the summer or server usage escalates.

Other industries impacted by volatile energy needs include oil and gas, retail and healthcare.

Microgrids to the Rescue: How Load-Leveling Powers Efficiency

Microgrids are self-sufficient energy systems that power a specific area, such as a manufacturing facility or data center. By definition, a microgrid can operate independently of the grid when needed, often relying on distributed energy resources (DERs) and a battery energy storage system (BESS).

The BESS helps the microgrid achieve greater power efficiency for the facility it serves. It plays a crucial role in load-leveling, or flattening out the peaks and valleys in energy demand, because it can store excess energy generated during low-demand periods and use it when high-demand periods hit. 

Behind-the-Meter Energy Solutions

Because of its ability to facilitate load-leveling, a microgrid offers businesses a behind-the-meter advantage for boosting power efficiency. It can use stored energy to shave off the highest points of peak demand, reducing energy bills. Because it works to even out demand, a microgrid can also reduce the stress on transformers, inverters, and HVAC systems caused by high peaks and sudden drops in power demand. 

Many microgrids also incorporate renewable energy sources like solar panels or wind turbines, reducing the facility’s dependency on fossil fuels and allowing the possibility of selling excess power back to the public grid. From the utility’s perspective, behind-the-meter systems like microgrids absorb spikes and present a flat, stable load.

e2Companies’ R3Di® System: More Than a Microgrid

Unlike traditional solutions that demand lengthy implementation and infrastructure upgrades, our patented R3Di® system offers a compact, all-in-one power platform that can be quickly deployed, with no interconnection agreement or expensive utility modifications needed.

Where Microgrid Efficiency Pays Off

Adopting the R3Di® System can result in microgrid energy savings by reducing peak demand charges, infrastructure spending, and more. Here’s a closer look at how an onsite energy system can help different businesses save:

• Data Centers
  Data centers demand ever-increasing power and often struggle to maintain load-leveling. Installing a microgrid with a smart energy management system like Grove365 can help manage power spikes in data centers and optimize essential cooling systems.
• Oil & Gas
  Remote field operations, such as oil rigs, can be difficult to keep connected to the public grid. Installing a microgrid can help oil and gas facilities reduce costly downtime, optimize loads, and draw from battery power during peak demand times.

• Retail Distribution
  Retail distribution centers must often maintain 24/7 operations in large warehouses. For grocery retailers, cold storage is another necessity. Microgrids can help maintain operational consistency and prevent equipment failure by providing a constant flow of conditioned power, even when the public grid goes down. The R3Di® System integrates with the site’s existing infrastructure, providing continuous, conditioned power and instantaneous load pick-up to keep equipment running seamlessly. It can also power EV charging stations for value-added services and additional revenue streams.
