Affordability of the energy grid

Enexis operates in a regulated market. The maximum tariffs are set annually by the ACM. All grid customers (households and businesses) share the costs incurred by grid operators through transmission tariffs. Our customers' tariffs are rising due to our work in the energy transition, higher costs of purchasing transmission capacity from the national grid operator TenneT, and rising prices.

Enexis expects the number of gas network users to decline through 2050 due to the energy transition. Enexis will need to incur costs to remove these gas connections during that period. These costs can range from hundreds of millions to several billions of euros. Enexis will be reimbursed for these removal costs through tariff regulation, which means that they will ultimately be borne by society. The removal costs are expected to result in an additional increase in tariffs for our customers.

Policy and measures: Affordability

In everything we do, we are mindful of the need to spend our money wisely. This is part of our public duty and helps to keep energy affordable for everyone. ^{(ESRS 2 MDR-P 65(c))} That is why we make optimal choices and work efficiently and effectively. ^{(ESRS 2 MDR-P 65(a)(b); ESRS S4 9(a))}

For example, we implement best practices at our sites, such as smarter use of technology and IT, and we encourage our different sites to learn from each other. We also control our costs by monitoring our spending. We prepare annual budgets that require approval from the EB and SB, and we report quarterly on progress. ^{(ESRS 2 MDR-A 68(a)(b)(c)}The budgets and intended measures are drawn up in collaboration with the relevant stakeholders within the various departments.^{(ESRS 2 MDR-A 65e,f)}

Metrics and targets

We monitor cost control through the CCR (controllable costs and revenue). The CCR is the sum of Enexis Netbeheer’s controllable costs and revenues (including staff departments). ^{(ESRS 2 MDRA-T 77(c)), MDR-T 80(a)(c)(f))}Non-regulated activities therefore fall outside the scope of the CCR. The CCR relates to operating costs and revenues and excludes net revenue and the associated costs of transmission services and distribution losses, depreciation expenses, and amortised contributions. The costs and revenues included in the calculation were not changed in 2025^{(ESRS 2 MDR-T 80f,i)}. Each year, we set a target for the CCR. The target for 2025 was to limit costs to €871 million. ^{(ESRS 2 MDRA-T 80(b)(e)}No baseline or base year applies. ^{(ESRS 2 MDR-T 80d)}

In 2025, controllable costs came to €849 million, which is €22 million below our target. Although we carried out more work than originally planned, costs did not exceed the budget. This reflects efficient processes and optimal resource deployment. As a result, we remained on track with our 2025 target.

The CCR was nevertheless €70 million higher than in 2024. The expansion of our work and the associated growth of the organisation led to higher costs, further amplified by the scarcity of materials and services, which continued to drive up prices. ^{(ESRS 2 MDR-T 80(j), MDR-A 68e)}
