We’ve just brought two new solar plants online in Alicante. And what that means for you goes well beyond megawatts.
The problem nobody mentions on your bill
If your company has a significant electricity consumption, you probably know the feeling of looking at your energy bill with quiet resignation. Prices go up, come down, and go up again. Nobody warns you when or by how much. And even if you signed what looked like a stable rate, wholesale market volatility finds its way into what you pay every month, one way or another.
This isn’t your supplier’s fault. It’s structural. The Iberian electricity market — MIBEL — sets prices hour by hour based on demand, fuel costs, and available renewable capacity. When gas prices rise, you feel it. When wind drops, you feel that too.
“The question isn’t whether prices will fluctuate. It’s whether your company can afford to keep being exposed to that fluctuation.”
There’s also another pressure that’s growing harder to ignore: sustainability is no longer just a statement of intent. Investors, auditors, clients, and European regulation are asking you to prove the origin of the energy you consume. And proving it doesn’t mean saying you have a “green tariff” — it means having Guarantees of Origin that are issued, traceable, and verifiable.
What’s changed at Prosolia Energy
For years we’ve worked as energy supply managers and consultants for businesses. We analyse consumption, structure contracts, optimise tariffs, and support our clients through their energy procurement decisions. We still do all of that.
But in recent years we’ve gone further: we’ve built and commissioned our own generation assets. That makes us an IPP — an independent power producer — and it changes something fundamental about what we can offer you.
We no longer just manage how you buy energy from the market. We can now sell you energy we produce ourselves.
Perleta I & II · Operational since 13 May
Two new solar installations in Alicante add 5.47 MWp of installed capacity and an estimated annual output of 11,467 MWh — solar energy with certified Guarantees of Origin, available for long-term supply agreements.
How a PPA works and why it matters for your business
A PPA — Power Purchase Agreement — is a long-term energy purchase contract between a producer and a consumer. You commit to buying a set volume of energy over an agreed period; we guarantee supply at an agreed price.
The value of the model isn’t in the contract itself — it’s in what it delivers for your business:
Price certainty, no surprises. You lock in your energy cost over the long term, either at a fixed price or with controlled indexation. What the market pays stops being your problem.
100% renewable origin, verifiable. The energy comes from identified installations. You can certify its origin with Guarantees of Origin issued in your name, valid for any audit or ESG report.
A stronger position with third parties. Investors, corporate clients, and regulatory frameworks such as CSRD and the EU Taxonomy value your ability to certify the origin of your consumption. A PPA resolves this cleanly and with full auditability.
Built around your consumption, not the other way round. We work with multiple generation technologies and different contract structures. What we propose starts from an analysis of how your company consumes energy — not from selling you a standard product.
Two PPA models: which one fits your business
Not all PPAs work the same way. Depending on the size of your consumption, your company’s financial structure, and your objectives, the agreement can take very different forms. These are the two main models:
- Physical PPA (own-asset or bilateral) This is the model Prosolia can offer you directly from Perleta I & II. You buy energy that we produce, with a known origin and an agreed price. It’s the most straightforward model: producer and consumer set terms without financial intermediaries. It works particularly well for annual consumption between 1 and 10 GWh, and for clients looking for a simple, operationally clean solution.
- Corporate or financial PPA (virtual PPA) This model involves no physical energy flow. It works as a contract for difference: you continue buying energy from your existing supplier, but you sign a parallel contract with a renewable energy producer that acts as a hedge against market volatility. If the market price rises above the PPA strike price, the producer compensates you for the difference. If it falls, you pay the difference to them. The net result is that your effective energy cost is fixed, regardless of what the market does.
This model is particularly well-suited to large consumers — typically from 10–20 GWh per year upwards — that cannot or do not wish to change their commercial supplier, operate across multiple countries, or want to certify renewable energy at scale without changing their operational supply. It’s also the model used by many companies with RE100 or Science Based Targets commitments to meet their decarbonisation goals in a verifiable way.
At Prosolia we work across both models — direct PPAs from our own assets and the structuring and advisory of corporate PPAs with third-party producers. If your consumption and objectives fit this format, we can support you from analysis through to signing.
What type of company does this make sense for?
A PPA isn’t for every company. The larger and more predictable your electricity consumption, the stronger the case. If your organisation consumes more than 1 GWh per year, or has multiple sites with distributed consumption, the cost structure likely justifies exploring a tailored agreement.
It’s also a strong fit for companies that already have public decarbonisation commitments — or know they will soon — and need to go beyond the green tariff available in the open market.
Sectors such as manufacturing, logistics, large-format retail, hospitality, and agri-food are contexts where this model works particularly well.
“It’s not about choosing between price and sustainability. With the right structure, both go hand in hand.”
What sets us apart
Many companies offer PPAs. Few have their own operational assets, in-house energy analysis capability, and experience managing complex corporate supply — all at the same time.
We come to the negotiation knowing exactly what sits behind the offer we’re making, because we built it. And we stay with you beyond the contract signing — managing your ongoing supply: access tariff optimisation, surplus management, regulatory adaptation, and everything else that comes with having your energy properly under control.
Perleta I & II are two more installations in that journey. There will be more.
Tell us how your current supply is structured and we’ll analyse whether a tailored agreement makes sense. No commitment, real data.
