3 Integrated Gas and electricity Modelling  What Impact will variable renewables have on the gas system?  Long term modelling to 2050 Overview of Presentation

4 Overview of Integrated Elec/Gas Model Builds on existing PLEXOS Power System model The Simplified Integrated Gas Model provides the capability to model the costs and constraints of gas delivery from its source fields via a network of pipelines, through storages and on to meet demands including those in the Electric Model. This integrated Gas/Electric Model is not intended to perform the function of a gas pipeline flow model. Rather, it uses a simple transportation algorithm to model gas flows Details of pipeline pressures and pressure drop functions not modelled. Storage volumes, pipeline flows and gas demands can be expressed in potential energy terms

5 2030 Model is a sub set of larger EU model. 15 minute resolution Gas model is currently only in AI Day Ahead and Real Time Modes (Stochastic or Independent samples) Model Coverage

7 Addition of Gas objects will impact on objective function to be minimized This can impact solution even if gas constraints are not binding  Generally small  Test and determine if significant  Use MIP or smaller gap Integrated Gas and Electricity Modelling With Gas Without Gas

8 ROI Gas and Wind Generation

9 ‘Flow’- Quantity of Gas Extracted from Pipeline (TJ)

10 Capacity Factors for CCGT

11 Annual Gas Storage (Simplified Gas Price)

12 Long term modelling

13 Only those countries with at least one MARKAL/TIMES modelling team active during the period are “painted.” >200 MARKAL / TIMES Users

14 Irish TIMES Integrated Energy Systems Model Linear programming bottom-up energy model Integrated model of the entire energy system Prospective analysis on medium to long term horizon ( years) –Demand driven (exogenous) in physical units Partial and dynamic equilibrium (perfect market) Optimal technology selection Minimize the total system cost Environmental constraints Energy and emission permits trading Price-elastic demands
