Governance scenario

Offshore Wind Connection Delay

A major offshore wind farm cannot connect because transmission reinforcement is years behind schedule. Clean power targets and investor confidence are at risk.

Back to scenarios

This is a fictionalised teaching scenario grounded in real institutional roles, published reforms, and current public-source context.

Scenario player

Work through the decision path below. Each choice changes the route, the institutional trade-offs, and the metrics the scenario tracks.

Offshore Wind Connection Delay

Step 1 of 2

NESO

Connection point identified but reinforcement delayed

A 1.5GW offshore wind farm is ready to connect in 2025 but the transmission reinforcement that it needs is not scheduled until 2028. The project is financed and scheduled. Delay will cost the developer GBP 40M in carrying costs. DESNZ is concerned that delays threaten the 2030 clean power target (40GW of wind by 2030). The network reinforcement was already scheduled before this project arrived, so the delay is not project-specific, it is network-wide.

What is at stake

  • -If you accelerate the reinforcement, you change network investment prioritisation.
  • -If you maintain schedule, you delay renewable capacity and increase costs.
  • -If you try to connect the project without reinforcement, you accept network risk.

What connection approach do you recommend?

Glossary

  • Dispatch

    Real-time instructions to increase or reduce generation or demand so supply stays in balance.

  • Balancing

    The continuous process of matching electricity supply to demand while maintaining system frequency.

  • Constraint

    A technical limit in the network that restricts how power can flow under current conditions.

  • Industry code

    A formal rulebook that defines obligations and processes for specific market and network activities.

  • Connection agreement

    The formal agreement setting technical and milestone conditions for connecting a project to the network.

  • Settlement

    The process that turns metered and contractual positions into final market cashflow outcomes.

  • Conformance gate

    A quality checkpoint that verifies whether data or implementation meets agreed standards.

  • LTDS

    Long Term Development Statement publication requirements for distribution network data.

Guided tour

Step 1 of 8

Who sets the rules?

Start with governance: policy direction, regulatory oversight, licences, and code obligations.

Why it matters: Newcomers should first understand where authority sits before interpreting operational decisions.

Sources and methodology

How this page was assembled

Scenarios are designed as regulator-safe teaching runs. Institutional roles, programme context, and cited reform pathways stay grounded in current public sources, while event details and numbers inside the run remain fictionalised unless explicitly evidenced elsewhere. This scenario is framed against Network Access Policy and DESNZ Clean Power Target.
