The Dutch government estimates that expanding and reinforcing its electricity network to support 40 gigawatts of offshore wind could cost up to €246 billion by 2040, posing significant challenges for affordability and industrial competitiveness.
The Netherlands is facing a steeply rising bill to expand and reinforce its electricity network, with revised government figures putting cumulative grid investment at €246 billion between 2026 and 2040 if the country proceeds with 40 gigawatts of offshore wind.
That estimate, drawn from the FIEN2026 report prepared by PwC for Netbeheer Nederland and published with the Dutch government’s spring budget update, comes with a wide range: €172 billion at the low end and €320 billion at the top. The spread underlines how difficult it is to pin down the cost of building an energy system that is being asked to decarbonise quickly while also accommodating heavy industrial demand and rapidly rising electrification.
The latest numbers mark a sharp increase on earlier projections. In the annual budget memorandum, the cumulative need for electricity infrastructure between 2024 and 2040 was set at €195 billion, based on 38GW of offshore wind. That was later revised to €212 billion for 2026 to 2040 at 30GW, before climbing again to €246 billion at 40GW, the target now embedded in the governing coalition’s plans.
According to the spring budget documents, two forces are driving the rise. One is straightforward inflation in the sector: labour, materials and specialised equipment have become more expensive faster than general inflation, reflecting tight supply across the grid industry. The other is a widening of the investment scope, as network operators have brought forward customer connection work and extended planning assumptions further into the future.
The scale of the programme is already visible in the annual investment profile. The government’s figures show grid spending rising from €12.4 billion in 2026 to more than €20 billion at its peak in the mid-2030s, before easing later in the period. Even under the lower wind scenarios, annual investment remains elevated throughout the forecast horizon.
For households and businesses, the key issue is how these costs will be recovered. The spending does not sit directly on the central government budget. Instead, it is financed by grid operators through equity and borrowing, then recouped via network tariffs approved by the regulator, the Autoriteit Consument en Markt. In practice, that means the cost shows up in energy bills.
The government is trying to soften the blow for smaller users through a redesigned tariff structure that shifts charges towards a more time-based, kilowatt-hour model. Officials estimate that about 60% of households will see some cushioning from the new system, although the remaining 40% will face larger increases. On the government’s own calculations, household and other small-user network charges would rise by an average of 4.7% a year between 2026 and 2040 in the 30GW case, and 4.9% at 40GW. Without the tariff reform, the increases would have been materially steeper.
The picture is less comfortable for industry. Large electricity users are expected to face annual tariff rises of 6.3% under the 30GW scenario and 7.7% at 40GW. That raises obvious concerns for energy-intensive sectors already weighing whether Dutch power prices and grid access remain competitive against neighbouring markets.
The government has acknowledged that problem. The spring budget sets aside funds to help reduce electricity costs for high-consuming firms, including €345 million in 2027 and €495 million in both 2028 and 2029, although a detailed spending plan is still being developed. The stated aim is to support strategic autonomy and level the playing field, but the underlying tension remains: the grid must be expanded, yet the resulting costs cannot be allowed to hollow out industrial competitiveness.
Grid congestion adds another layer of strain. The budget papers describe congestion, alongside labour shortages, as a key bottleneck for the Dutch economy. Although work is under way on 25 congestion projects in the high-voltage network, the queue for industrial connections remains a persistent obstacle for manufacturing, data centres and hydrogen projects. In many cases, investment decisions are being delayed because firms cannot secure enough certainty over future power access.
That is why the state’s relationship with TenneT matters. The budget records €3.3 billion from the sale of the operator’s German business, money earmarked for the new national investment institution. It also includes a reservation of €2.15 billion a year in 2028 and 2029 for TenneT Deutschland. While grid investment is formally kept off the main state budget, the public sector’s exposure through guarantees, loans and ownership stakes means the fiscal boundary is far less rigid than the accounting suggests.
PwC has argued elsewhere that the Netherlands needs to think more strategically about public investment, particularly when cash-based budgeting can make it harder to distinguish between day-to-day spending and projects that support future growth. Its analysis of offshore wind also points to a broader European challenge: subsidy-free development can work, but only if supply chains, financing structures and risk allocation are managed carefully.
The bigger question now is whether the Netherlands can deliver all three objectives at once: build a much larger offshore wind system, reinforce the grid fast enough to support it, and keep energy affordable for households while preserving industrial competitiveness. The latest figures suggest those goals are becoming more expensive to reconcile, not less.

It highlights the need for public investments to strengthen the country’s future earning capacity, emphasising the importance of distinguishing between current expenditures and investments that generate future growth and tax revenues. The article also addresses the impact of the current cash-based budgeting system, which treats all expenditures equally, potentially leading to prioritisation issues during times of limited budgetary space.

It highlights the potential of offshore wind to decarbonise the energy system, particularly in North-West Europe, due to stable and abundant resources and relatively high public acceptance. The article also discusses the challenges of subsidy-free projects, including the need for strong project management capabilities, price pressures throughout the supply chain, and the question of who will cover power market risks in a zero-subsidy future.
