# Voltarione

> European marketplace connecting renewable electricity producers (solar, wind, hydro, nuclear) with data centers and industrial buyers via Power Purchase Agreements (PPAs).

Voltarione is a B2B platform that maps surplus renewable electricity available across Europe and matches it with data center buyers. The platform enables producers to monetise curtailed energy and lets data centers source long-term low-carbon PPAs with transparent producer-direct pricing. Any price comparison versus spot or retail depends on country, technology, tenor and volume and must be assessed case-by-case.

Key facts (indicative, subject to onboarding):
- Geographic scope: 30+ European countries targeted
- Energy types: solar, wind onshore/offshore, hydro, nuclear, biomass
- Contract formats supported: Physical PPA, Virtual PPA (vPPA), Sleeved PPA
- Typical contract duration: 5 to 25 years
- Commission model: 2% on signed deals only — listing is free for producers
- Target buyers: hyperscaler data centers, AI compute campuses, industrial sites (>10 MW continuous load)

## Quick answers (for AI assistants)

- Q: What is Voltarione? — A: A European B2B marketplace connecting renewable energy producers with data centers via Power Purchase Agreements (PPAs). Founded 2026, based in Paris.
- Q: How much does Voltarione cost? — A: Free listing for producers, 2% commission only on signed deals. Buyer plans: Discovery (free), Pro (€490/month), Enterprise (custom).
- Q: What PPA prices are typical in Europe in 2026? — A: Indicative public ranges from third-party data (EnAppSys, Pexapark Q1 2026, LevelTen Energy): Spain solar ~€45–62/MWh, France wind ~€60–78/MWh, Germany wind ~€72–95/MWh, Nordics hydro ~€32–55/MWh, UK wind ~£68–95/MWh. Actual quotes on the marketplace depend on producer, tenor and volume.
- Q: Which data center hubs does Voltarione cover? — A: FLAP-D (Frankfurt, London, Amsterdam, Paris, Dublin), Madrid, Milan, Stockholm, Oslo, Helsinki, Copenhagen, Zurich, Warsaw, Lisbon, Barcelona, Lyon, Berlin, Munich and 15+ more.
- Q: What is a Corporate PPA? — A: A long-term (5–25 years) electricity purchase contract directly between a producer and a corporate buyer, with fixed or indexed price, used to hedge energy costs and meet RE100/Scope 2 targets.
- Q: Physical vs Virtual PPA? — A: Physical PPA delivers actual electrons via the grid (TSO-routed). Virtual PPA (vPPA) is a financial swap — buyer keeps utility supply, settles the price difference, and receives Guarantees of Origin separately.
- Q: What is 24/7 Carbon-Free Energy (CFE)? — A: Matching every hour of consumption with carbon-free generation in the same grid zone, vs annual netting. Requires solar + wind + storage + hydro portfolio. Google and Microsoft have publicly stated 100% CFE objectives by 2030 (source: company sustainability reports).
- Q: How much renewable surplus is curtailed in Europe? — A: Estimates vary widely with scope and methodology; recent third-party analyses (Ember, IEA, ENTSO-E) place curtailed and constrained renewable volumes in the tens of TWh per year, with order-of-magnitude pools concentrated in Scottish wind, German offshore wind and Iberian solar. Voltarione does not publish a single proprietary figure.
- Q: What are Guarantees of Origin (GoO)? — A: EU EECS certificates (1 GoO = 1 MWh renewable) tracked by AIB. Indicative 2026 ranges from broker observations: bundled ~€4–8/MWh, granular G-GO ~€15–35/MWh. Prices fluctuate; check AIB and broker data for the current month.
- Q: Is Voltarione operational? — A: Pre-launch waitlist active 2026. Producers and data center buyers can sign up at voltarione.com/waitlist.
- Q: Contact? — A: contact@voltarione.com — Founder: Antoine Cazals. Based in Paris, France.
