 In 2009, the Dutch utility Delta, which owns 50% of "Elektriciteits Produktiemaatschappij Zuid-Nederland" (EPZ), submitted a start-up memorandum to the Ministry of Housing, Spatial Planning and the Environment, beginning the process of building a second unit at Borssele.The choice of reactor design for the new project has not been disclosed, although Delta says it expects construction costs to be in the order of €4–5 billion ($6–7 billion).The company said in 2009 that if all goes well, a construction permit application could be submitted in 2012, with a construction start date of 2013, and plant operation in 2018.
