The ENSG Annual Report for 2006 Released

en español más abajo

The ENSG Annual Report for 2006 has recently been released.

The Electricity Networks Strategy Group (ENSG) provides advice to DTI, Ofgem, Defra, the Scottish Executive and the Wales Assembly, on issues associated with the development of the distribution and transmission electricity networks. The ENSG has a number of sub groups, the Distributed Working Group (DWG) and the Transmission Working Group (TWG).

The TWG is concerned with electricity transmission networks operating at 400kV and 275kV (and, in Scotland,at 132kV), while the DWG’s work relates to distribution networks operating at lower voltages and to which most consumers, and, increasingly, smaller generators, are connected.

The ENSG is chaired jointly by the DTI and Ofgem, and has senior representation from the Scottish Executive, the Welsh Assembly, DEFRA, the network operators, generators and other industry participants. It meets every 3 months and summaries of its meetings will be posted on this page.

ENSG Organizsation

The origin of the ENSG is the Distributed Generation Coordinating Group (DGCG). British government had taken a number of measures to support the development of small and micro generation technologies connected to the distribution networks close to the point of demand. Not least of these was the creation of the industry-wide Distributed Generation Coordinating Group (DGCG) which operated over a three-year period to November 2004 and which initiated a range of projects designed to address barriers to the integration of distributed generation. Building on the valuable work of the DGCG, the DTI together with Ofgem established in January 2005 the Electricity Networks Strategy Group (ENSG), which looks more widely at issues relating to the electricity networks while maintaining a focus on the development of distributed generation.

The 2006 ENSG Report has the following index:

El Electricity Networks Strategy Group (ENSG Grupo de Estrategia de Redes Eléctricas) asesora al Ministerio de Negocios, Empresas y Reforma Regulatoria (DTI, que ha asumido algunas funciones del antiguo Ministerio de Industria y Comercio), al regulador de gas y electricidad (Ofgem), al Ministerio de Medioambiente (Defra) británicos, al gobierno escocés (Scottish Executive) y al gobierno galés (Wales Assembly), en asuntos relacionados con el desarrollo de las redes eléctricas de transporte y distribución. El ENSG tiene dos subgrupos, el Distribution Working Group (DWG, Grupo de Trabajo de Distribución) y el Transmission Working Group (TWG, Gurpo de Trabajo de Transporte).

El TWG se ocupa de las redes eléctricas de transporte de 400kV y 275kV (y, en Escocia, de 132kV), mientras que el DWG se encarga de las redes de distribución que operan a tensiones inferiores a las que están conectados la mayoría de los clientes, y cada día más, los pequeños generadores.

El ENSG está presidido conjuntamente por el DTI y la Ofgem, y en él están representados los gobiernos escocés y galés, el Defra, los operadores de redes, los generadores y otros actores del sector eléctrico. Se reúne cada tres meses y sus actas pueden leerse en su página web.

El origen del ENSG está en el Distributed Generation Coordinating Group (DGCG, Grupo Coordinador de la Generación Distribuida). El gobierno británico había adoptado diversas medidas de apoyo al desarrollo de las tecnologías de la microgeneración que se conecta a la red de distribución en cercanía a los puntos de consumo. No fue la menos importante la creación del DGCG que funcionó durante tres años hasta noviembre de 2004, y que inició una serie de proyectos concebidos para atacar las barreras a la integración de la generación distribuida. Basándose en estos valiosos trabajos, el DTI y la Ofgem crearon en Enero de 2005 el ENSG, que contempla los asuntos de una forma más amplia en relación con las redes eléctricas manteniendo su atención en el desarrollo de la generación distribuida
