Media attention surrounding the opening of the Dutch green power market has doubled demand for green electricity in just 25 days after its opening, reports market monitor Greenprices. The rush for green power since July 1 has exceeded most expectations, with market research agency Datamonitor's last year prediction of 400,000 customers by 2005 being reached within two weeks of liberalisation. The three largest power utilities, Essent, Nuon and Eneco currently have between 130,000 to 150,000 green power accounts, while smaller power companies who have previously only offered green power to customers within their distribution areas are also witnessing spectacular growth. Zeeland's Delta utility, for example, has seen its number of green power customers jump from 4000 to 37,000 thanks to a spring advertising campaign. This rush to green power means that a quarter of the 150,000 households in Delta's distribution area now buy green. Market newcomers Echte Energie and Energieconcurrent, who specialise in green power retail, have each secured around 2000 switches.
