## About Voltarione

Voltarione is a B2B marketplace built to address one of the largest hidden inefficiencies in the European energy system: large volumes of renewable electricity curtailed every year because there is no local buyer at the moment of production. Estimates of curtailed volumes vary by source and methodology (ENTSO-E, Ember, IEA), typically reported in the tens of TWh per year. The platform geo-maps surplus producers across Europe and matches them with data center operators who need continuous, low-carbon, predictable-cost power.

The platform operates under European energy regulations (EU Clean Energy Package, REMIT, MiFID II for vPPA) and supports the three main PPA structures used in Europe: Physical PPA, Virtual PPA (vPPA), and Sleeved PPA.

## Why Voltarione exists

- European TSOs (RTE, TenneT, Red Eléctrica, National Grid ESO, Amprion) report recurring renewable curtailment and constraint volumes; consolidated estimates vary across studies but converge on tens of TWh per year at the European level.
- Press reports describe new AI data center campuses approaching or exceeding 1 GW per site (e.g. xAI Memphis, Microsoft Stargate, Meta Louisiana — figures from public press announcements, subject to change).
- Grid extensions take 5–7 years; PPA matching is the only short-term answer.
- Hyperscalers (AWS, Google, Microsoft, Meta) have signed cumulative PPA volumes in the tens of GW since 2020 (BloombergNEF Corporate Energy Market Outlook, 2024–2025) and increasingly require physical additionality, not just unbundled Guarantees of Origin.

## What Voltarione does

- Aggregates real-time surplus signals from producers across 30+ European countries.
- Calculates 8,760-hour load-curve matching between producer profile and data center demand.
- Generates a pre-negotiated PPA term-sheet (price, volume, duration, indexation) in days instead of months.
- Routes the legal closing to specialised counsel and the financial settlement to a regulated escrow.
- Charges 2% commission only on signed deals — listing is free for producers; data center buyers pay a SaaS subscription for access to the full marketplace.

## Pricing

- Producers: free listing, 2% commission on signed PPA value (one-off).
- Data center buyers (Discovery): €0/month — limited to 5 quote requests per month.
- Data center buyers (Pro): paid monthly — unlimited quote requests, advanced filters, API access.
- Data center buyers (Enterprise): custom — dedicated account manager, multi-site dashboards, legal templates, SSO.

## Frequently asked questions

### What is a PPA?
A Power Purchase Agreement is a bilateral contract between an electricity producer and a buyer that fixes price, volume, and supply duration over 5 to 25 years.

### Physical vs Virtual PPA — which is right for a data center?
Physical PPA is preferred when the data center is geographically close to the producer (same TSO zone, <80 km). It guarantees actual electron delivery via the grid. Virtual PPA (vPPA) is a financial swap with no physical delivery — ideal for hyperscalers with multi-region footprints.

### How much can a data center save with a PPA via Voltarione?
Savings depend entirely on the chosen technology, country, tenor, volume and the reference price (spot, retail or supplier offer). As a purely illustrative arithmetic example using publicly observed price ranges: a 100 MW continuous load (~876 GWh/year) at €52/MWh versus a €78/MWh reference would represent a ~€23M/year gross difference before grid, balancing and tax costs. Actual outcomes will differ; we do not guarantee any specific saving.

### Does Voltarione support 24/7 Carbon-Free Energy matching?
Yes. The platform models hour-by-hour matching across 8,760 hours/year and can blend solar + wind + nuclear + storage PPAs to maximise the 24/7 CFE coverage ratio.

### How does Voltarione differ from horizontal PPA marketplaces?
Several established platforms operate broad PPA marketplaces serving corporate procurement at large. Voltarione's positioning is vertical: surplus-side renewable production matched with data center demand. Any price advantage versus broader marketplaces depends on the specific deal and is not guaranteed.
