This often comes from a disconnect between supply and demand, especially with the increase of renewable energy sources that can be a bit unpredictable. Today’s grid relies heavily on long-distance transmission lines to move electricity from generation sources to population centers. It’s fascinating how those early debates still shape today’s transmission lines and energy management systems! Grid congestion is a big challenge in the energy world, making it tougher to distribute electricity efficiently and reliably. It’s also a key component of a lot of power traders’ strategies. There are constraints on the system most days, keeping everything working.

Gridraven’s CEO, Georg Rute, founded the company after realizing that hyperlocal wind forecasting wasn’t accurate enough for dynamic line rating.Gridraven The predictions are based on weather forecasts and a detailed terrain map made from satellite and lidar scans. Instead, it relies on machine learning to make accurate, hyperlocal wind predictions. The first project increased capacity by 31 percent on average, freeing lines to carry an additional gigawatt of power and saving customers £14 million annually (US $19 million).

In aggregate, widespread HEMS adoption turns homes and small businesses into active grid participants, supporting local voltage stability and even providing flexibility services back to the grid (e.g. via demand response programs). For instance, a HEMS might delay charging an electric vehicle or heating water until midday solar production peaks or nighttime off-peak hours. This orchestration not only protects transformers and local feeders but also maximizes fleet availability, reduces operational costs and avoids penalties from exceeding grid connection limits. It can prioritize charging based on departure schedules, battery state-of-charge or route requirements, while delaying non-urgent charging to align with off-peak tariffs or high on-site renewable generation. This coordinated approach, which links to an energy trading platform in Amsterdam, effectively creates a localized congestion market – a model now being watched by other EU countries.

Implementation relies on intelligent metering systems and standardized interfaces, enabling, for example, a EV charger or heat pump to pause or reduce output automatically when the DSO sends a curtailment signal. This targeted curtailment – usually applied to photovoltaic (PV) and wind – prevents overloads and stabilizes voltage without shutting down the entire plant. Western European countries are facing grid congestion in varying forms, but all share the imperative to balance decarbonization ambitions with infrastructure limits. The following sections outline western Europe’s congestion challenges and the modern strategies – from market reforms to digital energy management systems – being deployed to address them.

Consumption & Efficiency

The Dutch government, in partnership with grid operators and regulators, launched a Grid Congestion Action Programme in 2022 and is now enacting over 100 measures to ease the crunch. In households, smart heat pumps and batteries paired with HEMS can shift demand or store renewable output for later use, turning homes into flexible assets. Technical standards such as Engineering Recommendation G100 allow customers to connect PV and batteries with export limiters that cap grid feed-in, preventing overloads.

Amos Zeeberg is a journalist based in Bucharest, Romania, reporting on science and technology from an international perspective. Even in the extreme grid expansion scenario, where the total circuit length in Europe increases by more than a third, the redispatch volume would still surge nearly six-fold. By investigating different grid expansion scenarios, researchers have found that without swift action, redispatch volumes could increase almost six-fold by 2040, in a massive grid expansion (XGE) scenario in which the total grid length in Europe would increase by more than a third. Without swift action, redispatch volumes could increase almost six-fold by 2040, in a massive grid expansion (XGE) scenario in which the total grid length in Europe would increase by more than a third. This causes bottlenecks in many regions, known as grid congestion. As https://master-your-business.com/how-can-you-reduce-business-expenses/ the national knowledge platform on energy hubs, we help companies join forces to collectively manage their local energy systems.

How does power grid congestion affect energy prices?

The bank believes companies should seek more cooperation and negotiate jointly with grid operators to ease the pressure on the power grid. In light of this, Dutch businesses and grid operators fear power grid congestion across the Netherlands from 2026, which will slow down the country’s energy transition. DLR companies are quick to point out that the technology is not a cure for all that ails our grids; over the long term, we will simply need more transmission. Marmillo says it takes about 90 days of learning for the system to create accurate predictions of line capacities after it’s installed.

Oslo-based Heimdall Power, the manufacturer of the orb, has installed over 200 of them on the transmission lines of SH-Netz, the grid operator in the northernmost part of Germany. On a cloudy day in mid-July, a crew of technicians carries a shiny metal orb, about the size and weight of a kid’s bowling ball, under a 110-kilovolt transmission line running near Hamburg. Our articles, videos, and infographics inform our readers about developments in technology, engineering, and science. The implementation of bidding zone splits that prove to enhance market outcomes, is recommended to establish better incentives for efficient operation. Policy instruments aimed at mobilising investment, such as renewable auctions and capacity markets, can be improved by adding a locational component to reflect the local grid conditions.

Where Grid Congestion Happens

With this article, we aim to give international companies with operations in the Netherlands a clearer understanding of local grid capacity challenges and potential solutions. To ease the immediate pressure, grid operators and companies are exploring creative solutions to relieve grid congestion. Through GOPACS, grid operators can identify a looming overload a day ahead and then purchase corresponding reductions in demand or increases in local generation via a market mechanism. Heimdall is one of many companies, including Linevision in Boston and Gridraven in Tallinn, Estonia, providing the technology. Collaboration and coordination among various stakeholders, including policymakers, grid operators, energy producers, and consumers, will be essential in building a resilient and efficient power system for the future. The increased demand from electrolysers could concentrate in areas that are https://www.wisconsincentral.net/the-challenges-of-living-an-urban-life-in-wisconsin/ already experiencing congestion, intensifying the need for redispatch by at least 78 TWh in 2040 in a business-as-usual scenario based on a conservative estimation.

When a line or piece of equipment has too much electricity flowing through, it’s called grid congestion. Laurens explains that although large consumers, such as energy-intensive heavy industries, sometimes develop temporary fixes for grid congestion, the critical challenge lies in scaling these solutions into permanent frameworks. Aligns supply and demand more effectively, forecasts impacts of new technology and policies, and maximises local renewable energy use while reducing costly grid expansions. With these tools, grid operators gain insights into demand trends that help them pinpoint likely bottlenecks, allowing for more strategic, informed decision-making.

It’s earning about $21 per MWh, and it’s running at full power of 870 MWs. It shows that electricity needs to increase on the Northeastern side and decrease to the west of this constraint. If we toggle to see just the congestion component of the LMP, it’s just 37 cents per megawatt-hour (MWh) at all of these price nodes. Let’s look at Pennsylvania just outside of Scranton on an overcast Wednesday with seasonable weather, and let’s zero in at around 5 a.m.

• But with western Europe’s rapid push for renewable energy and electrification of transport and heating, these mismatches are happening more often, and smarter, faster solutions are needed beyond just laying more wires.
• This is evidenced by grid connection queues being present in at least 16 EU countries as of mid-2026, with data pointing to some 120 GW of mature renewable projects including 1.5 million household installations at risk of not getting timely grid access by 2030 (EMBER, 2026).
• Grid congestion happens when demand or generation in a local area saturates the capacity of the grid infrastructure (cables and transformers); it’s often described as a “traffic jam” of electricity.
• First, §9 of the Renewable Energy Sources Act (§9 EEG) allows grid operators to temporarily reduce grid feed-in from renewable generators when local or regional grid capacity is exceeded.
• “By dynamically controlling assets like EV chargers, heat pumps and batteries, we can prevent local overloads and costly upgrades while actually lowering energy costs for consumers.
• In households, smart heat pumps and batteries paired with HEMS can shift demand or store renewable output for later use, turning homes into flexible assets.

Renewable generators might need to be curtailed when their output can’t be exported, which can lead to inefficiencies in how the system runs and impacts investment returns. In import-constrained regions, local prices can sometimes climb quite high, especially as conditions shift from hour to hour, making the situation https://www.motonlegalgroup.com/business-purchase-agreement-pdf/ more volatile. However, when constraints restrict flow across important transmission lines, cheaper energy can get stuck behind the bottleneck, and the more expensive local units end up determining the market price. Ideally, the electricity system works on a merit order, starting with low-cost renewable or conventional generators and adding more expensive ones as needed. Tackling grid congestion requires a multifaceted approach involving technological advancements, policy initiatives, and consumer engagement.
