Clean Competitive Electricity from Coal<br />
“Lowest Cost of Ownership”<br />
� Lowest Investment<br />
� Utilizing Standardised Solutions / Moduls<br />
� Decrease of Costs by „Lessons Learned“ and „Active<br />
Experiencing“<br />
� Utilizing Proven Technology<br />
� Shortest Time for Errection (delivery and construction)<br />
� Low Costs for Maintenance<br />
� short shut-down period for repair and revision, large<br />
intervals between two shut-downs<br />
� spare parts on stock or delivery on demand<br />
� maintenance-friendly design<br />
� well-skilled staff of Owner<br />
� Optimal Logistics (choice of site)<br />
� High Availability<br />
Dr.Benesch 05.02.2008 Seite | 25<br />
Characteristics of modern coal fired<br />
<strong>power</strong> stations<br />
� site related coal logistics<br />
� coal fine grinding<br />
� low NOx combustion<br />
� supercritical boiler and steam<br />
parameters<br />
� single train air and flue gas systems<br />
� steam turbine with optimized cold end<br />
� use of CHP (areas of high population density)<br />
� air pollution control with secondary NOx abatement measures (due to<br />
local requirements), dedusting and flue gas desulphurization<br />
� flue gas discharge through cooling tower or wet stack<br />
� optimal automization and “lean” operation<br />
� competitive civil solutions dependent on site specific climatic conditions<br />

Typical areas<br />
Typical area for an additional 750 MW <strong>power</strong> <strong>plant</strong> on an existing<br />
site is 12 ha (app.30 acres) including coal yard for 10 day storage<br />
without switchyard and other infrastructure)<br />
pitch centre to centre boiler 750 MW: 100-110m<br />
FGD 1x750 MW unit: app. 1ha (2.5 acres)<br />
Lay down and preassemly area for 1 750MW unit 10 -14 ha<br />
(25 - 35 acres) typically not more available<br />
Dr.Benesch 05.02.2008 Seite | 30
Summary I<br />
The necessary space of a <strong>power</strong> <strong>plant</strong> in Europe is governed by<br />
the following aspects:<br />
typically no green field but brown field projects<br />
normally erection of one or max two new big 750 MW units, not up to<br />
six<br />
less predesigned lay out<br />
supplier independent design, meeting the possibilities of different<br />
manufacturers<br />
Typical area for an additional 750 MW <strong>power</strong> <strong>plant</strong> on an existing<br />
site is 12ha (app.30 acres) including coal yard for 10 day storage<br />
without switchyard and other infrastructure)<br />
Extreme examples show that also 2 x 660MW are possible in this<br />
area<br />

Summary II<br />
Typical area for an additional 750 MW <strong>power</strong> <strong>plant</strong> on an existing<br />
site is 12ha (app.30 acres) including coal yard for 10 day storage<br />
without switchyard and other infrastructure)<br />
In general the necessary space for the core components are the<br />
same in India and Europe.<br />
Major differences can be derived due to:<br />
two path instead of one path design<br />
other ash storage<br />
pre cooling lakes and water reservoirs<br />
local switch yards<br />
spare part storage<br />
preassembly areas and lay down areas<br />
higher investigated flue gas treatment systems in Europe<br />
bigger coal storage<br />
