15 DSM Initiatives in Spain Regulated tariffs Liberalized market Large Industrial customers Interruptibility Time of use tariffs Reactive control New Interruptibility Access to network tariffs Market prices Voltage control service Medium commercial customers Time of use tariffs Market prices Access to network tariffs Operational services Residential customers Night tariffs Operational services Price signals 15

16 Load interruption contracts 1st March 2005 Load Interruption of consumption Wind production Load interruption order sent from 17:30 to 23:30 1st March 2005 Coincident with low wind production Reduction of consumption of large customers to agreed values and with specific warning times as a request from the SO or distribution companies 16

17 Load interruption contracts 19th November 2007 Load interruption orders type C from 17:40 to 20:40 hours and from 17:45 to 20: Load interruption orders type C from 19:00 to 22:00 hours and from 19:05 to 22: Reduction of consumption of large customers to agreed values and with specific warning times as a request from the SO or distribution companies 17

Feed-back on consumption: Development of European Directives: Final customers should get information about their energy consumption in order to allow them regulate their own energy consumption. 19

20 Expectations and future trends: Services Perfil de Potencia demanda de un consumidor del sector servicios en un día laborable de invierno Services sector Electric energy demand 26% Servicios Resto 74% 0:00 1:00 2:00 3:00 4:00 5:00 6:00 7:00 8:00 9:00 10:00 11:00 12:00 13:00 14:00 15:00 16:00 17:00 18:00 19:00 20:00 21:00 22:00 23:00 Energy saving: Energy saving requirements based on: limitation of electricity demand, performance of thermal installation, efficient lighting systems, solar minimal contribution to hot water and PV minimal contribution to electric energy. Energy efficiency certificates: Energy efficiency certificates for new buildings: Methodology taking into account final hourly energy consumption that will provide information of final use profiles. 20

21 Expectations and future trends: Industrial sector Comparativa perfiles de P. demanda por dos consumidores sector industrial: uno compra su energía en el mercado de producción y el otro tiene tarifa con complemnto de interrumpibilidad (día laborable de invierno) Industrial sector Electric energy demand 44% 56% Industria Resto 0:00 1:00 2:00 3:00 4:00 5:00 6:00 7:00 8:00 9:00 10:00 11:00 12:00 13:00 14:00 15:00 16:00 17:00 18:00 19:00 20:00 21:00 22:00 23:00 Consumidor a Tarifa Consumidor a mercado Disappearance of regulated tariffs for high voltage customers in 1/07/2008: It may lead to the lost of modulation for the whole sector due to the lost of incentives introduced by tariff supplements (time of use tariffs). Energy Audits: They will allow detecting potential in saving and best practices in the industrial sector. 21

22 Index 1. The Spanish electricity system 2. Electricity demand in Spain 3. DSM in Spain 4. Conclusions

23 Conclusions Large tradition in large industrial customers providing operational services under regulated tariffs. New challenge due to liberalization of supply side: evolution to new services into the market. Existing measures: Interruptibility and modulation, both representing a big value for the electricity system and meaning an economical benefit for the industry. Need of introducing DSM in planning of the transmission system. Residential customers need for information of consumption. Large smart metering substitution plan. 23
