Innovative and flexible supply solutions are critical success factors in a market that is constantly evolving with the liberalisation of European gas markets, unbundling of the once integrated gas and utility companies and a shift in customers' demand patterns. Market participants are adjusting their procurement strategies to the new market conditions, thus facing the need to actively manage their portfolio in order to ultimately benefit from new market opportunities. E.ON D-Gas therefore offers tailor made Gas Supply Services to the Dutch market, which gives energy consumers the ability to meet the needs of competitive and reliable supply.
