Benefits and Opportunities of DER

According to the United States Environmental Protection Agency (EPA), more than 12 million distributed energy resources (DERs) currently operate on the grid. That number continues to grow. Utilities are proactively developing strategies to manage future DER expansion and capitalize on present-day opportunities. The recent FERC ruling (Order No. 2222) enables DERs to participate more easily in wholesale markets. These changes open new opportunities for the power grid, environment, and traditional utility companies.

DERs offer multiple benefits to the electric grid. Each new connection increases the system’s overall value. As more customers and devices join the network, the grid becomes stronger and more resilient than the sum of its parts. Beyond value, DERs enhance reliability by placing power generation closer to where it’s needed. This improves access to energy during peak demand and outages. When managed effectively, DERs provide local generation, energy storage, and load balancing. These features help utilities manage dynamic rates and reduce system stress. They also reduce transmission and distribution losses. This improves energy efficiency and lowers environmental impact.

According to Wood Mackenzie, solar power accounted for 37% of all new generation projects in the first half of 2020. Solar power purchase agreements also increased. By 2025, solar is expected to make up two-thirds of the U.S. DER market. The wind sector saw similar momentum during the same period. Whether deployed as DER or in centralized generation, both solar and wind allow utilities to deliver clean, reliable energy. These sources help meet customer demand and support the broader shift to renewable electricity. Together, they make a major environmental impact—especially as climate change takes center stage.

FERC Order No. 2222 allows regional transmission organizations (RTOs) and independent system operators (ISOs) to let DERs compete in wholesale energy markets. Although its full impact is still unfolding, this rule supports the shift to distributed energy. It also aims to lower costs and improve grid reliability. Utilities are using new tools to assess the cost and benefits of DERs by location, technology, and provider. Many are planning based on projected load growth and market dynamics. As DER adoption continues, utilities will explore new partnerships. They will also modernize systems to deliver cleaner, more efficient electricity.

Considerations from your Partner in Power – Excitation Upgrades and NERC PRC-019

Are you considering an excitation system upgrade or planning an AVR (Automatic Voltage Regulator) upgrade for your facility? Like aging relays and meters, older excitation systems eventually become obsolete and need replacement. Upgrading lets you take advantage of modern microprocessor-based features. These include event recording, flexible logic, and advanced monitoring and control across multiple communication protocols. In addition, newer excitation systems rely on readily available components. This improves reliability and allows faster part replacement when failures occur. If your facility operates a generating unit over 20 MVA, a synchronous condenser over 20 MVA, or a generating facility rated at 75 MVA or greater (gross), you need to consider NERC PRC-019 compliance during any excitation or AVR upgrade. NERC PRC-019 coordinates voltage regulating controls, limit functions, equipment capabilities, and Protection System settings. After completing an upgrade or new installation, you must update your NERC PRC-019 report with the relevant commissioning documentation. For applicable facilities, you must review NERC PRC-019 reports every five calendar years, based on your audit cycle. These reviews confirm proper coordination of excitation limiters and protections. Because audit requirements vary by system topology and technology, technical expertise is critical. A Professional Engineer can guide you through the process. They ensure you complete thorough studies, maintain current reports, and keep your system optimized. They can also program equipment, perform testing, and recommend improvements for your existing setup.

Introduction to Arc Flash Basics

Understanding Arc Flash Hazards Arc flash incidents are among the most common and dangerous hazards in the electrical power industry. These events occur when a fault causes energy to arc through the air, traveling from one conductor to another or to ground. Arc flashes usually result from equipment failures in systems with high available incident energy—a dangerous measure of how much energy a system can release during a fault. As little as 1.2 cal/cm² of incident energy can cause second-degree burns. Impact on Safety and Equipment Arc flashes don’t just damage equipment or cause downtime. They are also a leading cause of workplace injuries and fatalities. According to Industrial Safety & Hygiene News, over 30,000 arc flash incidents occur annually, resulting in more than 2,000 hospitalizations and 400 deaths. Common causes include misoperation of protection devices, incorrect settings, delayed trip response, and poor maintenance. Assessing Your Facility’s Risk To evaluate your facility’s arc flash risk, begin with a comprehensive study. This process includes data gathering, impedance diagramming, short circuit analysis, and incident energy calculation. In addition to analysis, the study educates employees about job-site hazards by defining protection boundaries, approach distances, arc energy levels, and PPE requirements specific to your site. Staying Compliant with NFPA 70E NFPA 70E requires you to review your arc flash study every five years or after any major electrical system changes. Once complete, label equipment with clear hazard warnings. These labels should also display the PPE required for safe access or work.
