for regassification plants, number of inhabitants served and power or average supply per inhabitantfor the networks;♦ physical features: route and length of power lines or gas pipelines, section of electricity conductorsor nominal diameters of the gas pipelines, morphological, geological, topographical and otherenvironmental elements of the site of a regassification unit, the size of the area served by thenetworks and their routes;♦ characteristics of the network and location of internal nodes and links with networks and/orpipelines;♦ typical sections of the gas pipelines;♦ typical construction of power lines;♦ technical features of the plants for depression and pumping, or regassification (for gas), ortransformation, or sectoring stations (for electricity);♦ technical features of the other service structures;♦ significant technical elements: important intersections, overcoming large gradients, marine pipelinesfor gas, remote control and telecommunications systems (with data and sketches).3.3.2.3 Feasibility and option analysisThe key information is the demand for energy, seasonal and long-term trends and the demand curve for atypical day.The options analysis should consider, for example, different technologies for transporting electricity(direct or alternating current, transport tension etc.), alternative routes for gas pipelines or power lines,different sites or various technologies (Onshore, Offshore Gravity Base, Offshore FSRU 39 or othertechnologies) for a regassification terminal, different district networks, and alternatives for satisfying thedemand for energy (e.g. mixed use of gas and electricity instead of just electricity, the construction of anew power station on an island instead of underwater power lines, etc.).3.3.2.4 Financial analysisThe financial inflows and outflows are:Financial inflowsFinancial outflows• Fees for energy transport • Investment costs• Other revenues - design- works- land- testing of the infrastructure• Operating costs- goods and services for production- maintenance- technical and administrative personnel costs- fuel and electricityAmong the investment costs, in addition to spending for the design, land, construction and testing of theinfrastructure, we must also consider those due to the renewal of the short-life components. The typicaltime horizon is 15-25 years.The maintenance and operating costs mainly comprise labour, materials and spare parts. In the case of thefinancial analysis of a regassificator project, the purchases of energy, commodities, goods and servicesused as inputs and needed for the day-to-day running of the plants, have additionally to be taken intoaccount.39Floating Storage Regassification Unit.109
