Integrated System for power sources rational use

Year: 2000

City: Ferrara

Country: Italy

The System took its start with

the ”Geo-thermal Ferrara Project” (Progetto Geotermia Ferrara) born to exploit
a geo-thermal source at 102°C under
the Municipality of Ferrara's surface (1000-1200m).

Reason to Be Selected

The most important peculiarity of
the System is the integrated use of different power sources aimed to thermal
energy production. This kind of energy is conveyed as hot water in a network
implemented to supply domestic heating energy, summer cooling (through special
refrigerator devices) and domestic hot water. In addition, the System supplies
agro-industrial activities (greenhouses, inland fisheries, drying plants, etc.)
with low temperature heat.

Energy sources involved in the
integrated System are:

-         geo-thermal source (12MW)
exchanging its energy with the water in the network,

-         urban wastes incinerator
recovered energy (9MW)through a co-generating turbo-alternator,

-         methane fuelled boilers
(42MW), only functioning to cover winter demand peaks and maintenance periods
of other sources.

To improve efficiency of geo-thermal
source the System include a battery of special tanks allowing to stock hot
water continuatively produced - but not entirely consumed throughout the year -
by this zero-impact source.

In 1999 the hot water network has
supplied with domestic heat and hot water about 3 millions m3 of buildings
and, in the next few years, a 50%increase is going to be implemented.

Lesson learned

In general, the most important lesson
learned by the local administration is that development policies based on
sustainability always put involved actors – and not only – in a
 win-win logic.
All partners in the best practice drawn a positive image, an enhanced know-how
and a profit from the experience and, in the meanwhile, citizens earn a better
urban context and an higher quality of life.

In1999 integrated system and hot
water network entered in their routine mode. From now on an enlargement of the
network is forecast both for urban use and activities exploitation. The City's
Urban Regenerating and Conservation Plan is strongly based on the network to
supply with heating power and hot water the interested area and buildings. A
new incinerator line – it will replace a dismissed old incinerator - will
support these new developments.

In recent years local development
policy has strongly based on the sustainability principle: a Local Agenda 21 process,
such as 10 inter-sectoral projects about urban quality of life, have been
activated by local government.

Amazing is the richness in
positive effects deriving from the partnership tool, especially if a
public-private partnership. This is the best way people dispose of technologies
and resources.

Many projects – smaller than this
– have been activated by different departments of the local administration
through the public-private partnership tools, this for many reasons: 1) to
exploit people know-how within the whole community, 2) to support private
activities, 3) to involve them in the local government and in the toward
sustainability process, and 4) to obtain acceptance and consequently to grant
success for the initiative.

The described practice found
itself “best” only after population acceptance and consensus. Citizens
involvement and consultation is certainly the strongest issue that makes your
project, programme,  plan or policy a
winning and sustainable one.
