In May 2026, ANRE Order No. 9/2026 handed Romania’s energy communities something they never had before: direct access to the wholesale electricity market, access to the balancing market, and the right to treat battery storage as a revenue source rather than a stranded cost. Behind the regulatory language sits a genuinely new addressable market, and a business model most of the country has not built out yet: aggregation.
For energy suppliers, aggregators, industrial parks, municipalities and storage operators, this is not a footnote to renewables policy. It is a market-entry signal. Romania now has, on paper, a fairly complete regulatory pathway from individual rooftop solar to organized energy community to commercially aggregated market participant. Whether anyone builds a real business on that pathway is the more interesting question.
What ANRE Order 9/2026 actually changes
Published in the Official Gazette (Monitorul Oficial no. 384) on 7 May 2026 and effective from the date of publication, the order covers registered renewable energy communities and citizen energy communities, not individual prosumers. The core changes are:
- Energy communities can sell surplus electricity directly on the wholesale market, on the same footing as any professional producer, and can also purchase electricity on behalf of their members.
- Communities gain access to the balancing market and other organized markets, plus the right to conclude bilateral contracts outside organized markets.
- Battery storage owned by the community or its members can be offered to network operators as a flexibility or balancing service, turning storage from a cost center into a revenue line.
- Communities can participate directly, which requires the relevant licenses, or indirectly through an aggregator or intermediary under contract.
- Communities must assume financial responsibility for the difference between forecast and actual delivery, known as imbalance cost, or transfer that responsibility contractually to a balancing responsible party such as an aggregator.
Licensing obligations scale with activity: generation, supply, trading, aggregation or commercial storage operation can each trigger a separate licence. Combined production and storage capacity under 1 MW is exempt, and further carve-outs apply to condominiums, NGOs, associations and foundations depending on how they use the electricity. A follow-up rule, ANRE Order No. 50 of 25 June 2026, created a National Register of Energy Communities: communities must register within 30 days of acquiring legal personality, late registration is allowed but flagged in the register, and the register itself only went live on the first day of the month after that order took effect.
A separate, related change lands on 1 October 2026: an amendment to the electricity supply regulation gives municipalities two formal ways to allocate locally generated power among community members, either proportional to each point’s consumption or through fixed shares set in the community’s own operating rules, and requires suppliers to give every customer free, granular online access to their own consumption data, with automatic alerts once a customer passes 80 percent of its estimated monthly usage.
Why this is a real aggregator opportunity, not just a compliance update
The regulatory change lands on top of an already fast-growing distributed generation base. By the end of March 2026, the Association of Prosumers and Energy Communities in Romania, APCE, counted roughly 305,000 prosumers, about 3.4 GW of installed PV capacity and 800 MW of battery storage, on close to EUR 2.2 billion of cumulative investment. Growth has not slowed: APCE logged 15,000 new prosumers in December and January alone, and projects the country will pass 400,000 prosumers by the end of 2026.
Almost all of that capacity sits behind individual meters, too small and too scattered to trade directly on the wholesale or balancing markets on its own. That is precisely the gap aggregation is built to close: pool many small, fragmented positions into one that is large enough, and predictable enough, to sell into organized markets.
A second regulatory push is arriving from the demand side. Transelectrica’s planned flexibility market, which closed public consultation in December 2025 and is expected to launch in spring 2026, will pay large consumers, and eventually households through aggregators, to reduce consumption in day-ahead auctions, with providers required to pass at least half of that revenue back to the end customers who actually cut usage.
The business case is not theoretical. VoltLink, an aggregator licensed by ANRE in January 2025 and backed by Therme Group, already manages production, consumption and storage across large industrial clients and pitches its own role in blunt terms: as CEO Viorel Beltechi has put it, aggregation is becoming essential for anyone who wants to be a proactive player across balancing and system services markets rather than a price taker.
Who should be looking at this market now
- Energy suppliers already holding a licensed customer base have the most direct extension path: adding an aggregation or balancing-responsible-party service on top of an existing supply relationship.
- Dedicated aggregator and flexibility platforms have a genuine greenfield opportunity, the regulatory door is open and the incumbent competitive set is still thin.
- Industrial parks and large industrial consumers with on-site generation or storage can now monetize flexibility directly, or form a community with neighboring facilities to reach a scale organized markets will actually trade with.
- Municipalities gain a concrete tool, backed by an EU push under REPowerEU for at least one energy community per municipality above 10,000 inhabitants, to turn public-building energy use into a managed, budgeted, and potentially revenue-generating portfolio.
- Storage operators gain a second revenue stream: balancing and flexibility services on top of, or instead of, straightforward energy arbitrage.
The friction that keeps this from being a sure thing
ANRE’s own execution record is the clearest reason for caution. The regulator took roughly nine months to publish the registration procedure for energy communities that stakeholders had been expecting since late 2025, drawing public criticism from APCE president Dan Pîrșan, who called it nine months for what should have been a simple administrative operation. Reporting on the episode also suggests ANRE initially tried to expand its own role from registrar to evaluator of communities’ internal rules, closer to Belgium’s more restrictive model than to the many EU states that impose no registration requirement at all, before backing off after pushback.
Balance responsibility is also a genuine operational skill, not paperwork. A community or aggregator that forecasts its position poorly pays for the imbalance out of its own margin, and the granular licensing thresholds, the 1 MW exemption line, the separate carve-outs for condominiums and NGOs, mean early movers will need real regulatory and forecasting expertise, not just a software dashboard.
Does this make Romania the right place to build an aggregation business
Opening wholesale and balancing markets to energy communities is not a uniquely Romanian move, the European Commission has pushed the same direction across the EU under REPowerEU. What is more specific to Romania is the combination of a distributed generation base growing faster than most regional peers, at over 40 percent year on year by capacity, with a legal pathway that now runs, at least on paper, from individual rooftop solar through registered community to aggregated commercial market participant. That combination is not common in Central and Eastern Europe today. Whether it converts into a mature market will depend on how quickly ANRE itself moves from writing rules to enforcing them predictably, and the regulator’s own track record on the registration table is the reason to treat “opportunity” and “proven market” as two different things right now.
Momentum Energy’s View
We read this as one of the more concrete market-entry signals Romanian energy regulation has produced in the last year. The distributed generation base already exists, close to 3.4 GW of prosumer PV and 800 MW of storage did not appear overnight, and it has been sitting largely outside organized markets simply because no one could trade it at scale. ANRE Order 9/2026, paired with Transelectrica’s flexibility market, gives that capacity a legal route to market. The businesses that move first, on licensing, forecasting capability and real balancing-responsible-party contracts, are the ones most likely to define what Romanian aggregation looks like before the competitive set fills in. We are watching ANRE’s own registration and enforcement pace closely, because that, more than the text of the order itself, is what will determine how fast this opportunity actually opens.
If you supply, aggregate, or operate storage or on-site generation in Romania, where do you see the fastest realistic path to trading through a community or aggregator structure? We would like to hear how others are underwriting the balance-responsibility risk this creates.
