Running assets from a remote operations center will challenge your alarm management approach. When operators are far from the equipment they control, alarms become their compass and drive most of the work, making asset performance depend on a calm alarm page rather than a flooded one.

Why It Matters

A remote operations center is a significant investment. You built a business case, funded the headcount, and stood up the supervisory control and data acquisition (SCADA) platform to lower operating costs and centralize control across a growing fleet. When alarms are noisy, inconsistent, or irrelevant to what a remote operator can actually do, that investment underperforms, and operators carry avoidable stress. Getting alarm management right protects the return you promised and keeps operations safe, compliant, and efficient.

Key Takeaways

• Start with operations, not configuration. Define what your remote team is responsible for and what tasks your operators shall be able to perform before you decide what counts as an alarm.
• Alarm only on conditions a remote operator can act on. If they cannot fix it, or no actions are required, then make it an event, not an alarm.
• Standardize point names, configuration, and displays, then normalize data so one wind turbine stop does not trigger hundreds of alarms.
• Measure operator performance, not only your alarm count and behavior. Work methodically, starting with the top nuisances.
• Avoid context switching by adding alarm response guidance inside the SCADA system – Your operators don’t need to switch between windows and spreadsheets.
• Separate remote and local views so plant maintenance activity does not clutter the remote console.

Start With Operations, Then Define the Alarm

This Ovation Users’ Group Conference session came from Frédéric Bouvet, Business Development Renewables for Enterprise Software at Emerson, who spent his career integrating gigawatts of hydro, wind, solar, and battery assets and once ran roughly 14 gigawatts through a single control room. Frédéric’s core message is that a healthy alarm program is core to asset performance and starts with a sound alarm philosophy and guidelines, not with the configuration screen.

Define your remote team’s responsibilities first. Decide what an alarm is versus what an event is, and give each priority level a clear, shared meaning. Then use those guidelines as the specification you hand to your SCADA and engineering teams, and as the requirement you write into new plant builds. Not the other way around. This is the step most teams skip under delivery pressure, and skipping it is what creates the pain later. Standards such as ISA 18.2 give you a framework, but you must make it your own based on your operations strategy and company organization.

Standardize, Then Normalize for a Mixed Renewable Fleet

Remote operations centers inherit diversity. Sites come in through mergers and acquisitions, engineering and construction contractors hand over different configurations, and original equipment manufacturers provide their own alarm definitions. Adopting all of that as-is guarantees inefficiency and operational headaches.

Standardization brings point names, alarm configuration, displays, and filtering into a common structure so operators read every site the same way. This same discipline applies across wind turbine controls, solar plant SCADA, and hybrid sites, and it is central to good renewable energy asset management software.

Normalization is the layer that helps you absorb the site configuration disparity you inherited. Data models, virtual points, and calculations let you normalize data and turn disparate information into a few meaningful signals.

A single turbine or inverter fault can generate hundreds of alarms for environmental, grid, or protection reasons. In the remote center, operators usually need one piece of information to act: whether the turbine stopped and whether it can be reset. Fewer, smarter alarms also mean less effort to implement and maintain.

Data Rightsizing, Guide, then Measure

Give operators enough data to operate, not every point in the database. Alarm at the highest asset level that makes sense, flag the main cause rather than every secondary fault, and use grouping features so a summary alarm rolls up the detail an operator can drill into on demand. Avoid turning every original equipment manufacturer flag into an enunciated alarm just because the vendor labeled it important, or bringing the whole site SCADA into your control room system – be deliberate.

Help your operators: add alarm response guidance where operators already are. Embedding alarm meaning and detailed next steps directly in the SCADA system removes context switching and turns tribal knowledge into a central, shared, current reference that new operators can rely on across shifts.

Collect alarm data, track volume and trends by priority and site, and focus on the top offenders instead of trying to analyze everything at once. Watch operator performance too: time to acknowledge, time to reset, alarms per operator, and ignored alarms, which often signal a misconfigured priority.

Separate Remote From Local, and Automate the Routine

The same event can mean different things from different seats. A tripped unit that plant personnel may not worry about immediately may require the Control Room operator to urgently notify the transmission operator or dispatch replacement generation. Use groups, filtering, and multi-network design so remote operators see remote-relevant priorities and site staff see site-relevant detail, and inhibit maintenance alarms during normal operations so troubleshooting does not flood the console. The SCADA system also becomes a collaboration tool.

From there, automate simple, high-frequency tasks, such as generating a work order in your computerized maintenance management system rather than logging into other systems – in a real-time environment, every second counts. Another example of operator assistance is automatically resetting simple, specific, high-volume turbine faults so operators can focus on higher-value tasks.
