Electrical Power 2
This progress paper is basically to help investigate problems which always arise from the
connection of a large 550MW solar thermal farm at Bulli Creek in Queensland which is at the
northern end of the QNI ( Queensland – New South Wales Interconnector). You are also to
define and size suitable energy storage. In the connection, there are some standards which
should basically check to enable this large firm operates perfectly as demanded by the firm
managers. The contractors will have to do some feasibility study on the difference and say
something on merit and shortcomings of solar thermal against the solar PV (Barroso, 2012)A
perfect evaluation of this project is basically based on the following subtopics (Service, 2014).
TECHNICAL PROGRESS
Before the actual construction of the solar thermal energy of 550 MW is done, there must
be an assessment of the solar energy resources. The scrutiny is basically done on satellite remote
sensing. And the beam radiation intensity should be mapped for a raster of 250 × 250 m to help
achieve the energy capacity of 550 MW in an open area without buildings and trees which can
result to shadows (Cédric Philibert, 2011). A large generating station like this face challenges
like an insufficient fund. Thermal solar always employs the use of very expensive semiconductor
materials which generate electrical energy from solar energy. It is also very expensive to
maintain such large firm (Engineers, 2012). The other bottleneck crucial issue is what solar
thermal systems can do in winter. They must take most of the load since there will be times when
both wind and PV are contributing almost nothing, and electricity can ́t be stored in very large
quantity except through ST heat tanks (Naam, 2013). Another issue of the solar thermal is that
during winter the output basically goes down to about 20%.

After that there, a site ranking for the solar thermal and this is basically done using the
sensing data of the ground. The region of 250*250 m which is set aside for the installation is
identified for the land use, ground coverage, vegetation, soil type, topography, hydrology as well
as the available infrastructure. The study in the site ranking is done with the anticipated
economical and technical of the solar thermal power plant. In the technical progress the
following are considered;
i. Engineering
 system engineering
 civil engineering
 equipment specification
 detailed plant design
ii. Procurement
 turbine generator
 other power block equipment
iii. Construction
 civil works
 solar field
 other construction works
