What does AI do in a smart grid, and why is it becoming essential?

AI helps grid operators make better decisions by rapidly processing huge volumes of data from sensors, smart meters, weather forecasts and operational systems. In practical terms, it improves load forecasting, spots patterns humans and traditional models can miss, and supports real-time control so the grid can respond to sudden changes in demand or generation. It is becoming essential because the electricity system is changing quickly: renewables add variability, extreme weather is more common, and new large loads such as AI data centres can appear and shift at speed. AI enables operators to move from reacting after the fact to preparing in advance, improving reliability while unlocking efficiency savings.

How does AI improve load forecasting compared with traditional forecasting models?

Traditional forecasting generally relies on mathematical models tuned using historic demand curves and seasonal patterns. That works well on “normal” days, but it can struggle when something unfamiliar happens and there is no relevant historical reference, such as unusual weather or a sudden shift in how people use electricity. AI models learn from complex, multi-source data and can adapt as conditions change, making them stronger at recognising and predicting atypical behaviour. The goal is not to dismiss legacy models, but to reduce the growing gap between forecast and reality on the days when errors are most costly, helping operators run the system more efficiently and avoid serious disruptions.

Can AI help prevent blackouts and improve grid reliability?

Yes, but it does so by strengthening preparedness rather than acting as a magic switch. More accurate, faster forecasting supports better scheduling of generation, storage and flexibility, and helps operators anticipate stress on the network before it becomes critical. AI can also support dynamic grid management by analysing conditions in near real time and recommending actions that keep frequency and supply–demand balance stable. Importantly, utilities treat this carefully because the consequences of mistakes are severe. AI works best as part of a broader resilience toolkit alongside established forecasting, market signals and experienced operational oversight, so decisions remain robust even when the system behaves in unexpected ways.

What can we learn from Hydro-Québec’s use of AI for load forecasting?

Hydro-Québec provides a clear example of how AI is adopted safely and pragmatically. After a proof of concept using a neural network on a single substation, the utility invested in years of research before deploying deep neural networks into production. It now uses AI for short-term forecasting within a 36-hour window, hourly forecasts 10–12 days ahead using meteorologists’ forecasts, and even longer outlooks based on “historic normal” weather values. Crucially, it runs AI alongside legacy models to compare outputs and flag significant discrepancies for human review. During a heatwave, one legacy model needed major corrections while the AI model successfully anticipated an unusual demand pattern, illustrating where AI can add the most value.

How can AI data centres support grid flexibility rather than simply adding demand?

AI data centres can be a difficult load to predict, particularly during model training, which can consume substantial power. However, they can also become a flexible resource if their workloads are orchestrated in response to grid conditions. Trials such as National Grid’s work with Emerald.AI explore “smart mediation”, where software observes data centre workloads, identifies which tasks are non-critical, and adjusts computing activity to shape electricity demand. This can include ramping down by a defined number of megawatts, holding reductions for an agreed period, and ramping back up gradually to avoid “snapback” that can destabilise the grid. Done well, it creates a more symbiotic relationship between digital growth and system reliability.

Nordex secures 508MW of wind turbine orders in Canada

The orders include N163 turbines and the first deployment of the N175/6.X turbines in Canada.

Nordex has received new wind turbine orders totalling 508MW, including a first order for its N175/6.X turbines in Canada.

These orders, placed by undisclosed customers, involve the supply and installation of 73 turbines to be delivered in 2027 and 2028, with each contract accompanied by long-term servicing agreements for the equipment.

They include both N163 turbines and the first deployment of the N175/6.X turbines, marking the entry of this model into the Canadian market.

The turbines are designed for cold climates and will feature Nordex's Advanced Anti-Icing System on the rotor blades to help maintain high availability during harsh Canadian winters by reducing ice-related downtime.

The company did not disclose the names of either the customers or the specific wind farms involved in these projects.

Nordex Group North America CEO Manav Sharma said: “We are thankful for the continued trust of our customers. The orders further strengthen Nordex Group’s market position in Canada.

“Our proven anti-icing technology continues to be a key factor for success in cold climate regions, and now with addition of the N175 to our offered products in Canada, we can help our customers maximise energy production year-round and help further reduce the levelized cost of energy.”

Nordex has installed approximately 57GW of wind power capacity across more than 40 markets since its inception.

Its manufacturing network extends across Brazil, Germany, India, Mexico, Spain and the US. The company's product range focuses on onshore turbines in the 4–7MW classes, developed to meet market demands in countries with limited available land and regions facing grid constraints.

In December 2025, Nordex secured contracts from Alliant Energy to supply wind turbines in Iowa, US, marking a major step forwards for wind energy in the region.
