Illustrative: a transmission grid, its load flows and a cascading outage

Energy transition risk and grid integration

A power system dominated by wind, solar and batteries behaves differently from one built on spinning machines, and the risks change with it.

03The discipline

The field and its scope

For grid planners, system operators, protection and control engineers, market analysts and regulators who need to assess stability, adequacy and flexibility in power systems with high shares of inverter-based generation.

04Measures

Quantities and units

05Methods

Methods and their limits

Each method is listed with what it assumes and where it fails.

06Debates

07Bodies and data

Bodies that set practice, and the data they publish

Bodies and standards are named so learners can find and apply their published work; the Academy teaches their use and links to the publisher, and no affiliation is implied.

08Simulator

Run the discipline's simulator

Energy transition risk and grid integration's own model runs in the scene at the top of this page: set its parameters there and play the steps. The separate chart simulator is left off this page so that it stays within its size budget.

  1. Report

    Expert panel explains the 2025 Iberian blackout

    The ENTSO-E expert panel's final report found the 28 April 2025 blackout in Spain and Portugal resulted from interacting factors, including oscillations, gaps in voltage and reactive power control and cascading generator disconnections, and recommended operational, monitoring and regulatory changes.

    Why it matters. It is the reference case for voltage control risk in high-renewable grids and shows local behaviour can trigger system-wide failure.
