PPC bets €24 billion on Balkan energy grids

Greece's former state electricity monopoly is reinventing itself as a regional energy-infrastructure company. PPC, now a listed group operating across southeast Europe, laid out a five-year plan to spend roughly €24.2 billion on power plants, grids, storage and data centres (PPC Group). That works out to about €4.8 billion a year, up from €3.4 billion under the previous plan, and would nearly triple PPC's renewable capacity from 7.2GW to roughly 19GW by 2030.

The scale is unusual for the region, where the energy transition has a specific bottleneck: not policy targets but physical infrastructure. Ageing distribution networks can't absorb new solar and wind fast enough. Coal plants are closing without enough flexible replacement. PPC is betting it can build what the region lacks, and that regulators and capital markets will fund the bill.

Consumers Pay First, Benefit Later

How grids get paid for matters more than how they get built. Distribution networks are regulated assets: PPC spends, the energy regulator approves a rate of return, and customers pay through network charges on their electricity bills (ANRE). Romanian and Greek households will likely see those charges rise before they feel fewer outages or lower wholesale prices. The infrastructure helps everyone eventually, but the cost arrives first.

PPC says 54% of the investment will come from operating earnings, 31% from new borrowing, and 15% from a share issue of about €4 billion (PPC Group). S&P raised PPC's credit rating to BB with a stable outlook, citing the equity raise and revised plan (Parapolitika). At end-2025, the company's leverage ratio (net debt divided by EBITDA, the earnings measure lenders use to gauge how much debt a company can carry) stood at 3.2 times, below its self-imposed 3.5x ceiling (PPC Group). BB remains two notches below investment grade, so PPC still pays more to borrow than its western European peers.

The plan is credible but depends on execution speed. PPC invested €2.8 billion in 2025, with 87% going to renewables, flexible generation and distribution (PPC Group). First-quarter 2026 EBITDA rose 40% year-on-year to €0.7 billion (The Diplomat Romania). Spending money is easier than turning construction into revenue. Assets with long-term contracts or regulated returns generate predictable income; selling electricity at volatile spot prices without a fixed buyer does not.

Romania Is the Execution Test

PPC bought Enel's Romanian distribution, supply and renewables operations in 2023 for about €1.9 billion, gaining roughly 3 million customers and 534MW of renewable capacity (Reuters). Romania now accounts for around 22% of PPC's group earnings, according to analyst estimates (ProtoThema).

That acquisition is already turning into physical work. Rețele Electrice România, PPC's distribution arm, operates about 136,000km of lines across Romania and has launched a tender worth up to 387 million lei for high-voltage upgrades across Bucharest and ten counties, covering substations, line extensions and network reinforcement (Rețele Electrice România).

Europe's Grid Gap Behind the Bet

PPC's plan makes more sense against Europe's wider infrastructure shortage. The European Parliament estimates the EU needs around €584 billion in grid investment by 2030, with more than 40% of distribution networks already over 40 years old (European Parliament). Connection queues are already blocking new renewable projects from reaching the grid (WindEurope). Distribution operators argue local grids remain under-funded despite carrying the growing load from rooftop solar, electric vehicles and heat pumps (EU DSO Entity).

Southeast Europe faces a sharper version of this problem. Greece and Bulgaria announced a joint push to speed up energy-market integration (BTA), but cross-border connections remain thin and coal retirements are outpacing new capacity.

PPC has made the most concrete private-sector infrastructure commitment in southeast Europe's energy transition. Equipment suppliers and contractors win the moment spending accelerates. Shareholders gain if regulated returns materialise. No public record yet shows a verified country-by-country capex split or a timeline of permits and connections. The open question is how much of the cost regulators let PPC pass to household bills, and how fast new substations and lines actually link up to the projects waiting in queue.
