Datahub (Estfeed)

Datahub (Andmevahetusplatvorm Estfeed) is Elering's central data-exchange system for the Estonian electricity market. Every retail switching, metering reading, BSP settlement and BRP imbalance flow in Estonia passes through it. Without Datahub access, no commercial activity on the Estonian wholesale or retail market is possible.

What it actually does

Datahub is the authoritative source for every Estonian connection point: who supplies it, what its meter readings are, when the contract last changed. When a customer switches retail supplier, the request goes through Datahub. When a BSP delivers balancing energy, the metered values flow back through Datahub. When Konkurentsiamet audits a BRP's imbalance settlement, the inputs come from Datahub. It is the operational spine of the market.

Why it matters for distributed flexibility

For an aggregator running thousands of distributed assets, Datahub access is the difference between operational and theoretical. Sub-15-minute metering, BRP-level data slicing, automated switching API — these are what make multi-asset balancing portfolios actually work in production. Datahub onboarding is one of the slower steps for a new BSP/BRP entering the Estonian market; allow 3–6 months.

Comparison with neighbours

The Nordic model converges on national datahubs: Datahub (Estonia, since 2013), Datahub (Denmark, Energinet), eSett (joint Nordic imbalance settlement). Latvia and Lithuania have their own. The EU Clean Energy Package (Directive 2019/944) mandates that every Member State implement datahub-equivalent functionality by 2025; Estonia was years ahead.
