Hack the Climate.
Save the Green Electrons.

Date: 28-30 September 2026
Location: Microsoft Ireland, Dublin
Teams: 3-5 participants per team, maximum 20 teams

Bring AI to the heart of Europe's energy transition

The Problem

Europe is building renewables faster than ever, but grids can't always deliver what they produce. When clean power can't reach the system, it's dispatched-down and green electrons are thrown away. This happens for system-wide stability limits (curtailment) and local grid bottlenecks (constraints). On top of this, market signals can take generation offline even when the grid could carry it. Predicting and reducing each is one of the biggest unsolved challenges of the energy transition.

The Sandbox

Ireland is one of the most wind-penetrated energy systems in the world — a compact, connected market where this challenge plays out in real time. That makes it the perfect testbed for solutions that can scale across Europe.

Your Mission

Using real energy datasets and Microsoft AI, build a solution that predicts, reduces, or eliminates dispatch-down and market-based curtailment — keeping every green electron on the grid. Demonstrate how your solution will bring value to users. The solutions should map to a deployable product, decision-support tool, or optimisation engine that could be adopted by TSOs, generators, or large demand side users.

Prove it in Ireland. Scale it to Europe.

Who is this hackathon for?

Professionals from the following disciplines should find the scope of this hackathon interesting:

Data Science & AI

Programmers, machine learning engineers, and data scientists ready to build predictive models for energy generation, grid load, and weather patterns.

Renewable Energy & Grid Operations

Engineers, analysts, and professionals working in wind, solar, and hydro power who understand asset management, energy storage, and grid injection constraints.

Climate Risk & Weather Analysis

Meteorologists, climate risk analysts, and environmental scientists who can contribute insights on weather forecasting, seasonality, and climate-induced generation spikes.

Energy Trading, Finance & Policy

Professionals working in energy markets, risk management, and carbon finance who understand the economic penalties of curtailment and the value of optimized energy dispatching.

Software & Infrastructure Engineering

Cloud architects, backend developers, and systems engineers capable of building scalable, real-time mitigation tools and monitoring dashboards.

Data sets

We are currently curating the data sets that will be made available to participants. These sets will include data from ENTSO-E Transparency Platform, such as generation, load, and prices, as well as data from other sources. We will provide more details on the data sets, including their sources, formats, and access instructions, in the coming weeks.
