In a state with peak power prices already up to AU$14,000/MWh, the peak power costs are indeed expected to rise further, if the PPA does not specify any minimum amount of electricity to be produced. The larger costs are due to the large‐scale generation certificates (LGCs), valued at around AU$80/MWh, the low interest loan of 110m$AU, and the indirect costs of the larger share of intermittent and unreliable electricity. The costs of the electricity produced by this technology is larger than the AU$ 78/MWh of the power purchase agreement (PPA). The dispatchability of this electricity production is also less than the expected. For a 135 MW net nominal capacity, the likely electricity production is less than the planned 495 GWh/year, corresponding to a capacity factor (CF) of 42%. The costs and electricity production of concentrated solar power (CSP) solar tower (ST) with molten salt (MS) thermal energy storage (TES) technology are here analyzed for the latest, recently dismissed, Aurora project. Examples of the use of these statistical results are presented to better understand the type of sky patterns at the location. In the main section, the statistics at the pixel location and in a 49x49 pixel zone around the point are described for a one year time series. Together with state of the art solar irradiation estimations, these statistical results can be used to determine several important factors for the choice of the best suited solar technology to use. Based on a long term result of APOLLO at a given point, we introduce a new use of this data, the APOLLO Cloud Product Statistics, to determine the typical cloud situations and spatio-temporal patterns at the location of interest. The APOLLO (AVHRR Processing scheme Over cLouds Land and Ocean, originally developed for the AVHRR instrument) methodology delivers cloud mask, cloud classification, cloud optical depth, and cloud top temperature as cloud physical parameters for all MSG (Meteosat Second Generation) SEVIRI (Spinning Enhanced Visible and InfraRed Imager) pixels with a temporal resolution of 15 minutes during daytime since 1st February 2004. As the clouds are one of the main influencing parameters to the solar irradiation, this additional information can be very valuable to understand location-dependent characteristics when selecting a solar generator's location and to decide on the type of technology most appropriate for the site.

In addition to this, it is possible to obtain from long term satellite images a statistical description of the clouds in the zone of interest.

In order to assess the potential electricity production of a solar plant, industry usually uses long term time series of irradiation data.
