Inverter-based resources, or IBRs, now supply a growing share of grid capacity, yet they behave very differently from the synchronous machines that utilities have modeled for decades. Because they convert direct current (DC) to alternating current (AC) through power electronics, they lack the inherent inertia as they connect to the grid through power electronic converters rather than synchronous machines.

Closing Measurement Gaps with Non-Intrusive Measurement Technologies
Plants often operate with measurement gaps that limit visibility into critical processes and assets. Organizations cannot improve what they do not measure, making accurate and accessible process data a foundational requirement for operational improvement.
Level Measurement: The Quiet Force Behind Safer, Smarter South African Mines
Measurement instrumentation is what lets a mine speed up without losing control. Measure the right points, control the process better, and you can push output while still meeting safety and sustainability goals.
Scaling Ovation for Data-Heavy Power and Renewable Projects
Solar sites are growing to 5 gigawatts, battery projects at 30 gigawatt-hours, and behind-the-meter data center projects reaching 10 gigawatts, with fleets of hundreds of sites and tens of millions of points. The Ovation Platform scales to address these challenges.
Advanced Battery Testing: Identifying Defects in Cells and Modules with AI and Machine Learning
Battery manufacturing operates at scale, where even rare defects can have an outsized impact. A single faulty cell can compromise an entire pack, leading to safety risks, recalls, and warranty costs. Traditional end-of-line testing methods often lack the resolution needed to detect these anomalies in high-volume production
From Smart Devices to Actionable Insights
Most devices are smart, but the data is often stranded in the device. What is usually missing is written instructions, carried through procurement and design, that say which data comes out, where it lands, and what someone does with it. Without the instructions, the asset management software ships uninstalled or installed but not utilized, the input/output cards get ordered without HART capability, and the plant starts up with 4-20 milliamp signals and nothing else.
Proven Design Principles for Building Effective Operator Displays
Emerson’s Mark Nixon has collaborated with Flint Hills Resources’ Ike Brackin and COP founder and Chief Human Factors Engineer at Beville, Dave Strobhar, on a new book titled Data-to-Information Handbook: Building Effective Display Systems for Refining Processes.
Guardian: One Platform for Enterprise Operations, AI, and Software Management
The Guardian™ Digital Platform is a unified digital platform for AI-enabled enterprise operations. It connects enterprise insights, software applications, and digital solutions, bringing together the systems, data, and expertise teams use every day.
Excitation Control: Theory, Failure Modes, and the Data That Explains Them
At a recent Ovation Users’ Group session, Matt Pizarchik, Excitation Engineer at Emerson, covered how voltage regulators work regardless of manufacturer, the most common failure modes in the field, and the diagnostics built into Ovation excitation controls.
Pressure Relief Valve Innovations for Safer, More Efficient Ethylene Production
PRVs are the last line of defense against overpressure in ethylene plants. They protect equipment and pipelines carrying flammable hydrocarbons through extreme temperature swings, high pressures, and corrosive service. When a valve leaks during normal operation, fails to reseat after relief, or suffers a bellows rupture, the consequences extend to emissions, product loss, and personnel safety.
Plan Your ONS 2026 Visit: Where Strategy Meets the Technologies Behind Better Decisions
