    • Energy storage for energy consumersMatchen van wensen en mogelijkhedenDutchPower symposium over EnergieopslagFrits Verheij, 10 mei 2011
    • Energy storage for energy consumers1. The balancing act of energy storage2. Applications of energy storage at various levels3. Energy storage enables growing need for flexibility4. Practical examples show value of energy storage 2
    • Focus in the energy market is changing … Affordable I II 3
    • … but how to keep the ‘triangle’ in balance?With billions of energy consumers, having different needs …… which might change during the energy transition phase? 4
    • The balancing act of energy storage Increase of (varying) RES + DG Fuel shift due to electrical vehicles, Ageing assets (grids + power plants) heat pumps, etc. DemandSupply Coupling of electricity, heat (and Increase of luxury resulting in higher cold), and transportation peak loads Increasing dependency on delivery Energy managementPhysical Market Storage facilities (electricity, heat, gas) integrated at home/offices/… Increase of energy trading, e.g. on More need for preventing grid the balancing market overloading, voltage support, Uncertainty of dealing with energy frequency control, PQ storage in a regulated market 5
    • Electricity networks of the future includingenergy storage 6
    • The Electricity Warehouse™ 7
    • Energy storage for energy consumers1. The balancing act of energy storage2. Applications of energy storage at various levels3. Energy storage enables growing need for flexibility4. Practical examples show value of energy storage 8
    • Energy storages at three levels in theelectric power system Bulk Storage Community Scale Above 50 MW, e.g. 25-100 kW devices sited on the low Pumped Hydro & CAES side of the distribution substationGeneration Utility Scale 250 kW to 2 MW modules with an emphasis on renewables and ancillary services 9
    • Electricity storage system ratings 10
    • Suitability of technologies for singleapplicationsTechnology Pumped D-CAES A-CAES Hydro- NaS Flow Lithium-Ion Lead-Acid Hydro genMaturity ++ + 0 -- + - + ++ Arbitrage Balancing Suitable Pooling Mechanisms needed Black-start e.g. via Smart Energy Flexibility of thermal power plants Application Islanding T&D-Deferral Industrial peak shaving Residential storage Economically Economically Cost Reduction Data Source: Attractive Mid-Term Attractive Necessary BCG and EASE 11
    • Applications at community scale Transportation – Plug-in hybrid vehicles – All electric vehicles Consumer products – Refrigerator / freezer – Boilers – Power tools – Mobile phones 12
    • Energy storage at three levels – part 2 Large scale Medium scale Small scale • Boiler • Heat and cold storage • Soil heat exchangeHeat • Mass of buildings • Geothermal e-storage • Thermo-chemical storage • Phase change material •… •… •…Electricity • Battery • CAES • Battery • Flywheel • Pumped hydro • Flywheel • Super capacitor • … •… •… • Gas-fieldGas • Gas tank storage • Gas tank storage • Gas grid •… •… •… 13
    • Energy storage for energy consumers1. The balancing act of energy storage2. Applications of energy storage at various levels3. Energy storage enables growing need for flexibility4. Practical examples show value of energy storage 14
    • More flexibility is needed, some options1. Fast controllable centralized power generation, including curtailment of e.g. wind power2. Increase interconnection capacity3. Smart ‘local’ energy, i.e. integration of DG, demand response, and active participation of end-users4. Energy storage 15
    • Energy storage adds value to energy sector Renewables: System operations: Decoupling demand Frequency control and supply Spinning reserve Absorb unpredicted Trade & Power Generation: Balancing fluctuations Control / load following Control and Energy management integration Peak generation Load levelling T&D: End use (industry) : Asset management UPS / Ride Through / Shut down Voltage control Peak shaving Power quality Optimization of energy purchase Grid stability by load shifting Reactive power 16
    • Some Remarks Storage has the ability to provide more than one service and can therefore (potentially) benefit from more than one revenue stream The main competitor for energy storage is not a gas turbine or another storage system but the realization of demand side management (DSM) Markets & Regulations don’t lead but follow, so timing is important The early bird catches the worm! 17
    • Which, where, when, what?Questions that need to be answered: Which type and size of storage is required? Where on the network should storage be installed? When should the storage system be charged / discharged? What are the costs and benefits?Network ? Demand and DG ? Storage ? 18
    • There is no one answer Storage systems can be applied for many different purposes The optimal location, type and size of storage system to be used depends on many factors The more functions the storage system needs to fulfill, the more complex the decision making process Modeling can support this process, demonstration can show the practical value 19
    • Large-scale Energy Storage in NL1. The balancing act of energy storage2. Applications of energy storage at various levels3. Energy storage enables growing need for flexibility4. Practical examples show value of energy storage 20
    • Introduction of GROWDERSGrid Reliability and Operability with Distributed Generation using Transportable Storage EC funded under 6th Framework Programme Goal: To demonstrate the technical and economical possibilities of existing electricity storage technologies– Realization of Transportable Flexible storage systems– Realization of an Assessment tool for optimal distribution network management– Description of conceptual directions for EU regulatory framework 21
