EnergySystemsIG Webinar: Joint planning of the gas and electric system at European level

Some take-aways from @anto4193 from @EnerginetDK on the joint planning of the gas and electric system at the European Level during the 6th @EnergySystemsIG Seminar


EU Climate Targets

European climate targets means a doubling of electrification by 2050 + efficiency increase.

Member States Targets

Differ between MSs, for example:

EC 347/2013 require TSOs and DSOs to deliver a consistent and interlinked electricity+gas market and network model, including transmission infrastructure/ storage/LNG facilities, priority corridors and areas+cost-benefit assessment methodologies


Before law of 2013 : plans were received with increasing gas demand (@ENTSOG) and decreasing gas (@ENTSO_E )

–> ENTSOs’ interlinked modelling process (#TYNDPs)

10 Year Network Development Plans (TYNDPs)

Last one: TYNDP2020


Contains shares of electricity and gas in different target years, different scenarios:

2-yearly development cycle of TYNDPs

Process: Scenario building –> screening (socio-economic welfare with market prices) –> cost benefit assessment, based on long-term scenarios of 2040

Electricity and gas network interactions

Investigation of interlinkage of sectors took place with the help of @_Artelys : is it enough to investigate a project in one sector, or should it be done for several sectors at the same time? (?dual assessment?)

Mapping @_Artelys resulted in

  1. Direct : “can be submitted as project”
  2. Indirect : “translated into demand”

types of interactions

…and project screening method to assess interlinkage of gas + electricity projects

…which was adapted by @ENTSOG and @ENTSO_E in their assessment (‘Interlinked Model’)

Cost-benefit assessment

Consists of 13 indicators for 166 transmission projects and 15 storage projects [3 scenarios, 3 climate years, 3 market modelling and 3 grid modelling tools]

Cost benefit assessment:

Individual investigation for each project

(green = projects under construction)

Link with Projects of Common Interest (PCIs)

TYNDP projects can apply to become a PCI Advantages: accelerating planning and “one stop shop? permitting

PCI based on:

Current status and future plans

Completed and ongoing projects for electricity (blue) and gas (red)

114 billion EUR investment is planned during next decade.

For now, 4 billion EUR has been spent. Small compared to total.

Questions and answers

How to decide what to build?

ENTSOs don’t decide with TYNDPs, but only provide information (13 indicators). @EU_Commission calculates then net present value with points system, translating the projects into monetary values. Afterwards market decides.

How to compare gas and electricity projects?

If there are competing projects either within or between sectors, the process is the same. Projects are described in an amount of money, on which the decision is based. Weighted with other indicators such as security of supply.
