What Joint Allocation Office does

Joint Allocation Office (JAO) S.A. is a Luxembourg-domiciled, non-commercial market infrastructure organization that operates the single trading platform for auctioning cross-border electricity transmission capacity rights across Europe. It was formed on 1 September 2015 through the merger of CAO GmbH (Germany) and CASC.EU S.A. (Luxembourg), and on 1 October 2018 was formally designated as the Single Allocation Platform (SAP) for all European Transmission System Operators (TSOs) operating under EU legislation. JAO is jointly owned by 26 TSOs across 23 countries, which are simultaneously its primary customers; it additionally serves 500+ registered market participants including energy traders and power exchanges.

JAO's core technology is the eCAT (electronic Capacity Auction Tool) platform, which supports long-term and short-term explicit capacity auctions across yearly, seasonal, quarterly, monthly, weekly, daily, and intraday products, plus shadow auctions that act as backup to Single Day Ahead Coupling (SDAC). The platform is complemented by SOAP-based web services APIs for automated bidding, document submission, and data retrieval; a Publication Tool for market data dissemination; a Utility Tool for implicit allocation processes; integrated clearing and settlement services linked to ING InsideBusiness banking infrastructure; and interconnector-specific auction modules (Nemo Link, IFA/IFA2, Viking Link, ALEGrO, Eleclink). The firm operates 26,000+ auctions annually, trades 700 million MWh of capacity per year across 41 bidding zones, maintains ISO 27001:2022 and ISO 9001 certifications, and serves approximately 80 employees from its Luxembourg-Hamm headquarters.

JAO's business model is non-commercial: it operates as a neutral, regulated utility-like infrastructure provider funded through service-level agreements with TSO shareholders, rather than via disclosed market-rate fees. Its revenue mechanics are not publicly disclosed and pricing is not transparently published; market participants satisfy financial obligations under a Financial Agreement with collateral requirements. Distribution is exclusively direct-to-counterparty via the eCAT platform (web UI and APIs), with supporting channels including LinkedIn, YouTube training videos, industry events (e.g., ETCSEE), and a Jira/Power Apps-based Service Desk.

Joint Allocation Office competitors and assessment

Company assessment

Direct peers

EPEX SPOT: European power exchange for day-ahead and intraday electricity markets, operating implicit capacity allocation alongside JAO's explicit auctions. Highly comparable as a European electricity market infrastructure provider serving the same TSOs and market participants.
Nord Pool: Nordic and Baltic power exchange providing day-ahead and intraday markets with integrated capacity allocation. Comparable to JAO as a regional electricity market infrastructure operator serving multiple TSOs.

Broad incumbents

European Energy Exchange (EEX): Part of Deutsche Börse Group, EEX operates European energy spot and derivatives markets across power, gas, and emissions. Comparable as a broad European energy exchange operator but with a much wider asset-class portfolio than JAO.
ICE Endex: Intercontinental Exchange's European energy exchange for power and natural gas derivatives and spot. Comparable as an exchange-like platform for European energy trading infrastructure, though with a derivatives focus rather than transmission capacity.

Regional players

SEMOpx: Operator of the Single Electricity Market for Ireland and Northern Ireland. Comparable as a regional electricity market infrastructure provider integrated with cross-border capacity allocation in its geography.
OPCOM: Romanian electricity and gas market operator running spot and ancillary services. Comparable as a regional European electricity market operator, though JAO handles the cross-border allocation layer that sits above national operators like OPCOM.
TGE (Towarowa Giełda Energii): Polish energy exchange operating electricity, gas, and CO2 markets with property rights and capacity products. Comparable as a Central European electricity market operator whose auctions sit alongside JAO's cross-border allocation services.
Gestore Mercati Energetici (GME): Italian energy market operator for power, gas, and environmental markets. Comparable as a national European electricity market infrastructure provider that interacts with JAO for cross-border capacity between Italy and its neighbors.

Others

Nominated Electricity Market Operators (NEMOs): Collective body of European power exchanges designated as NEMOs under the Capacity Allocation and Congestion Management (CACM) regulation. Adjacent to JAO as counterparties in the Single Day-Ahead and Intraday Coupling processes where JAO provides shadow-auction backup.
EFET (European Federation of Energy Traders): Industry association representing energy traders and market participants in European wholesale markets. Adjacent to JAO as the trade body representing many of the 500+ market participants active on JAO's auction platform.
