Sleeved PPAs in Romania: Connecting Renewable Projects with Industrial Energy Buyers

Imagine a factory in Romania. It may produce glass, cables, construction materials, packaging, automotive components or food products. It has large equipment, predictable consumption and a problem that can no longer be treated as a simple cost line: electricity. In recent years, the electricity bill has become an unpredictable character in almost every industrial budget. Sometimes it looks manageable. Sometimes it explodes. Sometimes the spot market goes down, but supply offers still come with risk premiums, complex pass-throughs and commercial conditions that do not clearly explain what electricity will cost in two, three or five years.

At the same time, somewhere else in the market, a solar or wind developer has a different problem. It has secured the land, worked on permitting, obtained or is pursuing grid connection, and has a project that could produce green electricity. But the bank asks a very simple question: “Who will buy the power?” Between these two worlds — the factory looking for predictability and the renewable project looking for bankable revenues — one structure is likely to become increasingly important in Romania: the sleeved PPA.

A sleeved PPA is a structure where the renewable producer and the final consumer agree the economic logic of the power — price, duration, volume, profile and guarantees of origin — but the electricity is delivered and commercially managed through a licensed supplier or trader. The structure is simple: renewable producer → licensed supplier/trader → final consumer. The producer has the electricity. The industrial client wants the electricity. The supplier makes the commercial delivery, invoicing, balancing, settlement and residual supply possible when the renewable project does not fully cover the client’s consumption.

That is the “sleeve”. This is not a private wire between the plant and the factory. Electrons do not physically travel with a label from solar park X to factory Y. The electricity enters the system, is traded, nominated, balanced and settled within the market framework. A sleeved PPA is therefore the structure through which an industrial consumer can benefit from the economics of a PPA without becoming an expert in all the operational mechanisms of the power market.

The opportunity exists now because the market is changing. The old logic was simple: the consumer requested 6-month or 12-month supply offers, compared prices, selected a supplier and moved on. The new logic is more strategic. Large companies are no longer buying only MWh. They are buying predictability, protection against volatility, credible green electricity, ESG reporting, budget stability and access to an identifiable renewable project. In parallel, developers can no longer rely only on the idea that “the market will buy the power”. Renewable projects are increasing, prices may become more volatile, low-price and negative-price hours are becoming more relevant, and banks are paying closer attention to how the project will monetise its electricity.

This is why a PPA is no longer just an electricity sale contract. It is a financing, hedging and industrial strategy instrument. A sleeved PPA is one of the most practical forms for the Romanian market because it combines long-term contracting with the existing supply infrastructure of a licensed market participant.

Romania has all the ingredients for this market to grow. There are solar, wind, hybrid and BESS projects in development. There are industrial consumers looking more seriously at energy costs. There are multinational companies with decarbonisation targets. There are lenders asking for contractual revenue visibility. There are suppliers and traders capable of building products that are more sophisticated than standard annual electricity supply. But there is also one difficulty: the market is still maturing. Not every Romanian PPA is a sleeved PPA. Not every green supply contract is a PPA. Not every guarantee of origin means that the consumer is actually supporting a specific new renewable project.

That is why the discussion must go beyond labels. The right question is not: “Does the contract say sleeved PPA on the cover?” The right question is: who produces the electricity, who buys it, who commercially delivers it, who bears imbalance risk, who supplies the client when the plant does not produce, who transfers the guarantees of origin, who invoices the consumer and who takes the credit risk? If a licensed supplier sits between the producer and the consumer and performs these functions, then the structure is very close to the practical logic of a sleeved PPA.

Let us take a simple example. A factory has significant annual consumption and wants to cover 40% of that consumption with long-term solar electricity. A developer has a 50 MW solar project expected to reach COD in 2027. The project needs a long-term offtake contract so that the bank can finance construction. Commercially, the two parties fit: the factory wants green electricity, and the producer wants a stable buyer. But the factory does not want to manage wholesale market access, imbalances, nominations, shaping, night-time residual supply or multiple settlement flows. It wants a clear invoice and a product it can understand. This is where the supplier enters. The supplier buys or takes the electricity under the PPA structure, integrates it into its portfolio, manages the market side and supplies the final client with a product reflecting the economics of the PPA. The factory is not buying only solar electricity. It is buying a solution. And the producer is not selling only MWh. It is selling a more bankable revenue profile.

For a developer or project owner, a sleeved PPA is not only a commercial contract. It is a financing tool. A merchant project tells the bank: “We will sell electricity into the market and hope prices are good.” A project with a PPA tells the bank: “We have a long-term buyer, a price formula, a supplier managing delivery and a more stable route to market.” The difference is significant. For a developer, a sleeved PPA can improve bankability, reduce merchant risk, create a stable revenue base, support financing, increase the project’s sale value and make an RTB project more attractive to investors.

One important point: the developer does not always need to sell 100% of the production under a PPA. Sometimes the smarter structure is to contract 40%, 50% or 70% of expected generation and leave part of the project exposed to the market. This gives the project a stable revenue base while preserving some upside. This is where the real art of structuring appears. A PPA should not destroy the project’s flexibility. It should provide enough stability to support financing and enough exposure to keep the project commercially attractive.

For an investor, a project with a credible PPA structure is easier to assess than a fully merchant project. In due diligence, the investor will look at the PPA term, fixed price or indexation formula, buyer credit quality, role of the supplier, treatment of guarantees of origin, allocation of imbalance risk, termination rights, assignment mechanics, lender step-in rights, change-in-law risk and compatibility with project financing. A good PPA can increase project value. A bad PPA can reduce it. A long-term contract is not automatically an asset. If the price is wrong, the risks are badly allocated or termination is too easy, the contract becomes a liability rather than a value driver.

For an industrial consumer, the sleeved PPA is a strategic procurement tool. It is not only a way to buy green electricity. It is a way to bring discipline to a cost that has become increasingly difficult to control. An industrial client can use a sleeved PPA to lock in part of its electricity cost over the long term, reduce dependence on annual supply tenders, buy renewable electricity linked to an identifiable project, support ESG targets, diversify procurement strategy and reduce exposure to volatility.

However, the client must avoid a very common trap: comparing the wrong prices. A PPA price of EUR 70/MWh does not mean a final invoice of EUR 70/MWh. The PPA price is only the energy component. On top of it, there may be sleeve fees, balancing costs, shaping costs, residual supply, transmission, distribution, system services, taxes, contributions and VAT. Therefore, the right question for the client is not only “what is the PPA price?”, but “what is my total delivered cost, what risks remain with me and what percentage of my consumption should I cover through this structure?”

It is rarely prudent for a consumer to cover 100% of its demand through a simple renewable PPA. Renewable production is variable, and the company’s consumption may not match the generation profile of the asset. If we are talking about a solar pay-as-produced PPA, generation comes mainly during daylight hours and mainly in higher-irradiation months. If the factory consumes at night or has significant winter demand, the difference must be covered through residual supply. If we are talking about wind, the profile may be more balanced, but still variable. If we are talking about a hybrid portfolio of solar, wind and BESS, the product can become closer to the consumer’s actual needs.

In practice, many consumers should analyse scenarios such as: 20-30% of consumption covered by PPA, 40-60% of consumption covered by PPA, PPA only for daytime consumption, PPA combined with standard supply, PPA with a fixed price and market component, PPA with floor/cap/collar, PPA with guarantees of origin included or a portfolio PPA rather than a single-asset PPA. The right answer is not the same for everyone. A consumer with a flat profile, high consumption and low risk appetite will need a different solution from a flexible consumer able to shift consumption to cheaper hours.

For suppliers, a sleeved PPA is an opportunity to move from simple electricity resale to higher-value structured services. The supplier is no longer only the party sending a price offer. It becomes the structuring party. It can provide sleeving, balancing, residual supply, shaping, portfolio aggregation, guarantees of origin, tailored green products, hedging solutions and integration of generation from several sources. This is a more sophisticated business than classic supply and reflects the likely direction of the market: less commodity, more structuring.

Batteries may become one of the most important pieces of the PPA market. The reason is simple: one of the biggest problems of renewable electricity is profile. Solar produces when the sun shines. Wind produces when the wind blows. The client consumes when it needs electricity. The market pays differently in every interval. This difference between production, consumption and price is an opportunity for flexibility. A BESS can help shift solar electricity from low-price hours to higher-value hours, reduce imbalance exposure, create a more shaped product for the consumer, improve capture price for the producer, reduce curtailment risk and support a more attractive PPA product.

As the PPA market matures, simply selling pay-as-produced renewable electricity may not be enough. Consumers will want clearer products. Banks will want more stable revenues. Suppliers will want better optimised portfolios. This is where BESS can become the commercial shock absorber of renewable electricity.

Still, the sleeved PPA is not the only solution. For an SME that only wants green electricity, a standard green supply contract may be enough. For a medium-sized industrial consumer, a PPA-backed green supply product or simplified sleeved PPA may make sense. For a large industrial consumer, sleeved PPAs, virtual PPAs or PPA portfolios may be analysed. For a developer with an RTB project, a physical PPA or sleeved PPA may support bankability. For an owner of an operational project, a combination of partial PPA and merchant exposure may be more attractive. For a BESS owner, the opportunity may be in shaping, firming and flexibility services around PPAs.

The biggest mistake is to choose the structure before understanding the problem. You do not start with “I want a sleeved PPA”. You start with better questions: what risk do I want to reduce, what consumption do I have, what generation do I have, what price do I need, what flexibility do I accept, what ESG obligations do I have and what can the bank finance? Only then do you choose the structure.

If you are a developer or project owner, before looking for a PPA you need to clarify the project status, installed capacity, approved export capacity, realistic COD, grid connection position, expected generation profile, P50/P90 scenarios, the percentage of production you want to contract, the type of PPA you want, the treatment of guarantees of origin, your position on balancing and curtailment, lender requirements and the exit scenario. In other words, you are not selling only electricity. You are selling a risk profile.

If you are an industrial client, before signing a PPA-backed supply offer or sleeved PPA, you need to analyse annual consumption, hourly consumption, day/night profile, seasonality, the percentage you want to cover through the PPA, the price formula, treatment of negative-price hours, who bears imbalance costs, who supplies electricity when the renewable project does not produce, whether guarantees of origin are included, the all-in delivered cost, financial guarantees required from you, whether volumes can be reduced and under what conditions the contract can be terminated. A good PPA can be a competitive advantage. A badly structured PPA can become a long-term trap.

The most frequent mistakes are five: comparing the PPA price with the current final invoice price, ignoring balancing and shaping costs, assuming all green electricity is the same, contracting too much volume and signing a 10-year contract without clearly understanding exit rights. In electricity, price is important, but risk is often more important than price.

It is also worth clarifying the difference between a sleeved PPA and a virtual PPA. In a sleeved PPA, there is a physical delivery logic through a supplier. The consumer receives a supply product that reflects the economics of the PPA. In a virtual PPA, the consumer does not physically receive electricity from that project. The producer sells electricity into the market, the consumer continues to buy electricity from its supplier, and the producer and consumer financially settle the difference against an agreed strike price. A virtual PPA is closer to a financial hedging instrument. A sleeved PPA is closer to a structured physical supply product. Which one is better? It depends on the profile, sophistication and objectives of each company.

If you are a developer, you start with the project profile and the question: what product can I sell, to whom and with what residual risk left in the project? It is not enough to say: “I have a 50 MW solar project.” You need to explain COD, generation profile, grid connection status, curtailment risk, guarantees of origin strategy, contractual flexibility and bankability needs. If you are a consumer, you start with your consumption. It is not enough to say: “I want cheaper electricity.” You need to explain your hourly consumption profile, budget exposure, ESG targets, risk appetite, operational flexibility and the percentage of demand you want to cover strategically.

The sleeved PPA matters because it solves a real problem. On one side, renewable energy producers need stable, financeable and credible revenues. On the other side, industrial consumers need predictable, green and economically explainable electricity. Between the two stands the supplier, trader or structuring party that makes the electricity deliverable, invoiceable, balanceable and usable as a commercial product.

This is the opportunity. Not just signing a contract. Not just buying green electricity. Not just selling renewable generation. The real opportunity is to build a structure where each party gains something tangible: the developer gains bankability, the owner gains project value, the investor gains revenue visibility, the client gains predictability and decarbonisation, the supplier gains a higher-value product and the BESS asset gains the flexibility role that makes the entire system smarter.

Romania is still at the beginning of this market. That is precisely why the opportunity is significant. In a few years, discussions about PPAs, guarantees of origin, shaping, balancing, BESS and structured green supply will no longer feel exotic. They will be normal. The companies that understand these mechanisms earlier will negotiate better, finance more easily and buy electricity more intelligently.

The energy transition is not built only by developing solar and wind parks. It is also built through the contracts that give them economic meaning.
