System Operators

The ‘Modulator’ pulses signals into the grid and alters the frequency of the power system slightly. Terna had ten frequency measurement devices installed around the island. These frequency measurement devices accurately measure the minute changes and send the data to the GridMetrix system hosted in the cloud. Reactive Technologies uses Grid-Sonar to extract the necessary data and is then able to measure grid inertia in real-time and with 95% accuracy.

Achieve Net Zero

Our Accurate Grid Inertia Measurements solution, powered by the Grid-Sonar monitoring mechanism, provides you the Accurate Grid Inertia Measurements you really need to help you make informed decisions to keep inertia high and the renewable grid frequency stable

With a stable grid you will reach Net Zero faster, by rapidly scaling up renewables and scaling down fossils.

Grid-Sonar has proven to be 95% accurate. As validated in the lab, with trials, and with both small and large grids such as National Grid ESO and TEPCO.

Minimize Risk

By acting on Accurate Grid Inertia Measurements, you will no longer be driving blind. Our Accurate Grid Inertia Measurements will empower you to respond efficiently to events on the grid and make energy forecasts. This real-time data allows you to make key decisions about ramping up renewable energy sources on your grid, while also eliminating the risks of low inertia and grid frequency instability.

Optimize Processes

Gain grid insights and leverage grid visibility for maximum cost optimization. By making accurate decisions about energy demand based on real-time data, you’ll see huge cost savings. Our clients are making six-figure cost savings thanks to the grid visibility gained through our innovative cloud-computing technology.

The Challenges

One of the biggest barriers to reaching Net Zero Carbon is maintaining high inertia on the renewable grid.

High inertia means high stability for the grid and lower chance of power blackouts. The old grid relies on fossil fuels to maintain high inertia.

But on the renewable grid, inertia isn’t guaranteed. The more renewables, the less inertia, the more grid instability. If inertia is low it could, at worst, lead to blackouts across the power grid and, at best, cost a lot more to secure.

Right now, stakeholders have no big picture view of the renewable energy supply chain. Driving blind, they have no choice but to make conservative decisions to maintain high inertia. Conservative decisions mean doing what has always been done in the past – relying on fossil fuel energy sources.

Renewable energy sources on the grid will only increase if the ability to monitor the inertia accuracy, now and into the future. With this ability, utilities don’t need to buy too much renewable inertia, frequency response, or leave fossil fuels running.

What if we told you that we’ve developed a mechanism that can continuously monitor Accurate and Real-time Grid Insights for the entire grid? A mechanism that can flag issues on the grid so you can jump into immediate action to maintain renewable grid stability?

We have that mechanism today. We call this mechanism Grid-Sonar.

Accurate Grid Inertia Measurements empowers System Operators

Accurate Grid Inertia Measurements empowers System Operators
We have developed an innovative solution that provides grid operators the data they really need to keep a renewable grid stable. That solution is Accurate Grid Inertia Measurements.

Our Accurate Grid Inertia Measurements gives System Operators a complete view of inertia and system strength across the power grid in real-time.

The real-time visibility of critical network conditions will empower you to make key commercial and operational decisions faster, safer, and more cost-effectively.

By being able to measure key stability metrics, you will be more in control of your grid allowing you to accelerate your renewable energy transition, meeting government deadlines in record time. System Operators across the globe are already using Accurate Grid Inertia Measurements, as they go full throttle into their energy transitions. The energy revolution begins with accurate grid inertia measurements.

Reactive Technologies’ Accurate Grid Inertia Measurements are being successfully used by National Grid ESO in the UK and demonstrations from Tokyo Electric Power Company (TEPCO) in Japan, Italy, New Zealand, and Australia.
