WPW is a joint venture between NUON, a Vattenfall company and the Municipality of Amsterdam. Each own 50% of the shares. WPW distributes the heat and delivers it to different clients. Although it does investments and collects money, it has no personnel. No personnel cost is therefore attributed to them in City-zen, they are only participating with investments in the demonstrations in Amsterdam (WP5). As they have no personnel, the contact persons are within Nuon and within the City of Amsterdam. Given the close operational connection with the production of heat (done by AEB), the listed contact for the City of Amsterdam is within AEB.
Nuon began construction the district heating system in Eastern Amsterdam in 1993. First Amsterdam South East was connected, after which the system was extended into Amsterdam South. The next district to be connected was IJburg. The WPW joint venture began in Westpoort in 2000, followed by the Amsterdam New West (2005) and Amsterdam North (2008) urban districts and other areas. 50,000 residential equivalent (RUE) are now connected to the system. The growth is around 4,000 REU per year.
In the Eastern part the gas fired power plant (NUON/Vattenfall) is connected to the district creating a 50% savings in energy and CO2 emissions, in the Western part the municipality owned Waste Fired Power Plant (WFPP) is connected to the district creating a 80% savings on energy and CO2 emissions.
Role in City-zen
Since there is no personnel involved in the joint venture (all personnel directly associated with the mothers of the joint venture) the only partner role is that all major infrastructural investments is via WPW.
