decontamination if any;- the technical characteristics and the state <strong>of</strong> the high voltage grid that interconnects the project energygenerating plant; particularly, for installations that generate discontinuous and variable electricity power(wind, pho<strong>to</strong>voltaic, tidal, waves), the technical capacity <strong>of</strong> the electricity grid <strong>to</strong> compensate for thesechanges should be demonstrated;- describe the engineering features <strong>of</strong> the infrastructure, as follows:♦ basic functional data, such as: type <strong>of</strong> plant for producing electricity 49 , installed capacity (MWe) andenergy produced (TWh/year); annual potential capacity <strong>of</strong> well fields (millions <strong>of</strong> barrels/year ormillions <strong>of</strong> m 3 /year), <strong>to</strong>ns <strong>of</strong> CO 2 saved;♦ key parameters for the RES plants, such as: level <strong>of</strong> resource risks (wind/hydro), estimated loadfac<strong>to</strong>rs, supply during peak demand, levelled generating costs;♦ physical and site characteristics 50 ,♦ building, technological and processing techniques for the production plants;♦ building techniques and technical features <strong>of</strong> the plants for mining wells, e.g. <strong>of</strong>f-shore platforms,attaching building and functional sketches;♦ building techniques and technical features <strong>of</strong> the other service structures;♦ treatment systems for waste water and fumes, with the number and positioning <strong>of</strong> stacks and waterdischarges;♦ significant technical elements, such as the constructions in caverns, dams, special technicalsolutions for waste treating, computerised control systems, telecommunications systems, etc.3.3.3.3 Feasibility and option analysisKey information: the demand for energy, seasonal and long-term trends and also, for electricity powerstations, a typical graph <strong>of</strong> the daily demand for electricity.The comparison in the options analysis should consider possible alternatives within the sameinfrastructure (e.g. different technologies for production and drilling, different technologies for ash andwaste treatment, etc.). Possible realistic alternatives for producing the energy required should also beconsidered (e.g. launching actions and policies aimed at energy saving, instead <strong>of</strong> building a new powerstation).3.3.3.4 Financial analysisThe financial inflows and outflows are:Financial inflowsFinancial outflows• Sale <strong>of</strong> energy • Investment costs- Sale <strong>of</strong> gas - works- Sale <strong>of</strong> electricity - land- Sale <strong>of</strong> heat - test <strong>of</strong> the infrastructure• Additional State incentives • Operating costs• Reduced costs for the purchase <strong>of</strong> energy - goods and services for production- maintenance- technical and administrative personnel costs- fuel and electricityThe time horizon is usually around 15 – 20 years.49In the case <strong>of</strong> hydroelectric plants (production and/or pumping) linked <strong>to</strong> aqueducts, one must also bear in mind the technical data suitablefor the aqueduct sec<strong>to</strong>r (see the relative outline).50For example: the area covered by the well field (Km 2 ) and the position. In the case <strong>of</strong> <strong>of</strong>f-shore drilling, it would also be useful <strong>to</strong> providelocal bathymetric pr<strong>of</strong>iles; average depth <strong>of</strong> deposits (m); area occupied (Km 2 ) by plants (thermo-electricity) and relative s<strong>to</strong>rage areas, location <strong>of</strong>dams, pressure water-pipes and genera<strong>to</strong>rs for hydro-electric production; area occupied by fields <strong>of</strong> pho<strong>to</strong>voltaic or wind genera<strong>to</strong>rs (Km 2 ) andtheir location, area covered by geothermal well fields (Km 2 ) and plant position.113
