| Footage description: | John Naughton, in the studio, introduces the programme. Various shots of Rotterdam showing, in particular general traffic with trams prominent. Ian Lowe, standing in one of the streets, gives a brief introduction to Rotterdam. Various shots of a residential building site outside Rotterdam. Lowe points out that all these houses will be heated from a central communal system. Shots of the pipes which carry the hot water being laid. Ian Lowe, inside his car, explains the principles behind a central heat and power system (CHP). He points out that it works much like a car heater which utilises waste heat from the engine to warm the car. Shots of the inside of Schiehaven Power Station in Rotterdam which runs the CHP system in the city. Commentary by Ian Lowe points out the machinery there and how the hot water for the system is generated and controlled. With the aid of animated diagrams, Ian Lowe explains how one can calculate the amount of heat which is being supplied by a CHP system such as that at Rotterdam. Taking readings from gauges there, Lowe does the actual calculations. He then shows why this CHP scheme is more efficient than a power station alone. Ian Lowe goes on to explain how the ratio of heat and electricity generated is changed to meet demand. W. Zaandbergen, a director of GEB Rotterdam (the municipal energy authority), explains that the destruction of much of the city during WWII enabled a CHP system to be installed as the city was reconstructed. He then goes on to explain why CHP was also used in the new developments outside Rotterdam. B. Bearboom, another director of GEB Rotterdam, explains how the overall efficiency of fuel use at Schiehaven compares with that of conventional power stations. Zaandbergen gives his view on the reaction of consumers to CHP. Ian Lowe discusses the difficulties of metering heat supply to consumers in CHP systems. In Rotterdam a collective metering system (one meter for several houses) is used. Shots of a collective metering station. Commentary explains how the amount of heat used here is calculated. Zaandbergen sums up, briefly the pros and cons of metering heat supplies to individual homes. Zaandbergen gives his views on who benefits from combined heat and power schemes. Over aerial shots of Rotterdam, Ian Lowe sums up the programme. |
