Bulgaria, Romania, Croatia and Hungary are among more than a dozen EU member states resisting European Commission plans for preferential electricity taxation and common rules for calculating grid charges. The Commission wants to make electricity structurally cheaper than gas, while governments are seeking room to tailor costs to domestic conditions.
The disagreement is about who controls price signals and how quickly national systems can absorb them, not simply whether electrification is desirable. Southeast European grids differ in their generation mix, investment needs, cross-border congestion and share of regulated customers.
That makes a single EU template contentious for countries with different network requirements. Shifting costs between electricity and gas can affect household bills, industrial competitiveness and the bankability of electrification projects.
Grid costs and investment
Grid charges are particularly sensitive as network investment accelerates. Bulgaria reports more than 182 million euros in transmission investment in 2026, while Romania, Croatia and Hungary are dealing with large renewable, storage or interconnection programmes.
European policy seeks faster electrification, but expensive grid expansion is needed before lower electricity charges can be sustained. For Southeast European countries with lower incomes and significant industrial demand, political tolerance for bringing those costs forward is limited.
The likely regional outcome is a differentiated transition: member states continue supporting electrification while seeking flexibility over its pace, tariff structure and the allocation of costs among households, industry and public budgets. Those choices will shape how grid expansion costs reach consumers and businesses.
