Energy security now means keeping supply adequate and affordable while the system electrifies, decarbonises and becomes more weather-dependent, so the field's risks sit at the joints between fuels, grids, weather and markets.
Energy as a field of risk covers the reliability, security and transition of the systems that produce, store and deliver power, heat and fuels, and the services that depend on them. In the Nexus Consortium it is studied as science at GCRI by Energy Nexus as well as Data and Compute; this gateway links those platforms and the methods they share.

A power system with high shares of wind and solar is exposed to multi-day low-output periods that coincide with cold or heat-driven demand peaks; a gas-dependent system is exposed to global LNG competition. Resource adequacy assessment has moved from deterministic reserve margins to probabilistic metrics such as loss-of-load expectation and expected unserved energy, run on many weather years.
| Framework or body | What it governs or supplies |
|---|---|
| IEA energy security mechanisms and outlooks | Oil stock obligations, gas and electricity security analysis |
| Transmission system operator reliability standards (for example NERC in North America, ENTSO-E in Europe) | Planning and operational reliability, resource adequacy assessments |
| IEC 61850 and IEC 62443 | Substation automation communication and industrial control security |
| IAEA safety standards | Nuclear safety, including external hazards to plants |
The science sits on Energy Nexus; methods start from power engineering.
Each term as this page uses it. Where a standard-setting body defines the term, the wording follows that body.
| Term | Definition |
|---|---|
| Energy security | The uninterrupted availability of energy sources at an affordable price, in the IEA's definition, with long-term and short-term dimensions. |
| Resource adequacy | The ability of a power system's supply and demand-side resources to meet demand at all times, assessed with probabilistic measures such as loss of load expectation. |
| Grid resilience | A power system's ability to withstand, absorb and recover from high-impact events such as storms, heat waves and cyberattacks. |
| Black start | Restarting a power system after a total or partial shutdown using generators that can start without external electricity. |
