  1. SIMILARITIES AND DIFFERENCES IN THE STRATEGIC ASSET SIMULATION FOR ELECTRICITY AND GAS DISTRIBUTION GRIDS Klaus Peters RWE Rhein-Ruhr - Germany Armin Gaul RWE - Germany Heiko Spitzer entellgenio - Germany Terence Dürauer entellgenio - Germany Frankfurt, 09.06.2011

  2. Asset management capabilities in the electricity and in the gas sector have reached a new level • The main challenge for the asset manager is to balance conflicting targets over time • General targets are sector independent, e.g.: • save revenue, minimize costs and increase profits • ensure asset availability and quality • obey regulatory constraints • (re)consider investment and maintenance strategies Technology Regulation AssetManagement Finance Customer Klaus Peters, RWE Rhein-Ruhr / Armin Gaul, RWE / Heiko Spitzer, entellgenio / Terence Dürauer, entellgenio – Germany – paper 0825

  3. The different history of electricity and gas grids leads to different starting points • main grid extensions took place in different point in time • “position” of the grid in its lifecycle is unequal • closed circle of renewal for gas grids are (often) not yet completed (e.g. expected lifetime of pipes) • different development of grids in the future expected - schematically - gas grid electricity grid Klaus Peters, RWE Rhein-Ruhr / Armin Gaul, RWE / Heiko Spitzer, entellgenio / Terence Dürauer, entellgenio – Germany – paper 0825

  4. Using asset simulation in different sectors, sector specific parameters have to be adapted • specific plant safety aspects • specific technical rules (VDE/DVGW – German Technical and Scientific Association for Gas and Water) predefine some parameters to a specific valid range (e.g. maintenance interval) – still having hundreds of decision parameters • specific technologies, e.g. grid design, materials, mechanical stress, .. • specific external requirements, e.g. regulatory aspects or requirements through “EEG” (Renewable Energy Sources Act) and different customer needs asset simulation tool- schematically - Klaus Peters, RWE Rhein-Ruhr / Armin Gaul, RWE / Heiko Spitzer, entellgenio / Terence Dürauer, entellgenio – Germany – paper 0825

  5. Tools and methods can be adapted – as long as specific parameters and targets are retained • similarities concerned asset management and the appliance of tools and methodologies • individual parameters, targets and dependencies have to be represented in an appropriate way • strategy benchmarks described in the paper can be adapted to the needs of an electricity distribution grid provider and may be enhanced with specific required key figures • combination of tools and methodologies (e.g. asset simulation, sensitivity analysis, strategy benchmark, asset optimization) enables asset managers to focus on their core competences while regarding a wider range of requirements Klaus Peters, RWE Rhein-Ruhr / Armin Gaul, RWE / Heiko Spitzer, entellgenio / Terence Dürauer, entellgenio – Germany – paper 0825
