Capacity Planning

We use hourly system results to identify how much generation, storage, network capacity and flexibility will be needed, where it is needed and when it should be built.

The planning question

What generation, storage, network capacity and flexibility does each scenario require, by location and year?

We compare demand with the generation, storage, interconnection and flexibility available in each scenario. Shortages, curtailment, utilisation and flows show where the system needs more capacity or a different mix.

Demand, weather, technology costs and policy all change the answer. We report a range across scenarios and show which investments are needed in each case.

Experience

Experience from real modelling and planning work.

01

Adequacy and constraint analysis

Our work follows hourly and annual system behaviour across countries and climate cases. We use shortages, curtailment, price spreads, utilisation and cross-border flows to identify whether the limiting factor is energy, capacity, flexibility or network access.

02

Infrastructure pathways

We connect model outputs to generation, storage, conversion, import and network needs across planning horizons. The sequence matters: a robust pathway shows what is required now, what remains conditional and which later choices depend on earlier infrastructure.

03

Economic analysis

We assess capital and operating assumptions, asset revenues and system value where the question requires it. We also state what the calculation excludes, such as unmodelled revenue streams or simplified market treatment.

How we work

How we move from the question to an answer.

  1. 01Set the standard

    Define the reliability, policy or investment decision the plan must support.

  2. 02Establish the baseline

    Reconcile demand, existing assets, networks and committed projects.

  3. 03Stress the pathways

    Test weather, timing, cost and flexibility assumptions across credible cases.

  4. 04Plan the sequence

    Separate actions needed across all scenarios from choices that depend on later results.

What the team receives

What your team can continue to use.

  1. 01Capacity need by technology, location and planning horizon
  2. 02Adequacy, flexibility and network-constraint assessment
  3. 03Scenario comparison with assumptions and limitations
  4. 04Decision sequence, dependencies and review points

Partnerships & consortiums

We work with partners when the question needs more than one area of expertise.

We are open to partnerships and consortiums with system operators, public bodies, research organisations, infrastructure developers and technology teams.
