With a unique experience in design and delivery of large scale steam generators systems for CSP plants, Aalborg CSP has been awarded the order for a 25MWe steam generator system for the Gujarat Solar One concentrated solar power (CSP) project.
Gujarat Solar One CSP project is carried out by Cargo Power and Infrastructure Ltd. with Lauren Engineers & Constructors as EPC Contractor. The CSP plant is the first to be built in the state of Gujarat, where it is to be located in Rapar in Jutch district of Gujarat. The project is the first in India to use thermal energy storage, providing energy from the collected solar power for up to 9 hours.
When the CSP plant goes online it will utilize the key features of Aalborg CSP's improved steam generators, the SGS3 system, The optimised system won international recognition ( Supplier and Technology Award)in 2013 due to the operational benefits it provides.
SGS3: increased performance, higher availability
The Aalborg CSP steam generator technology is developed based on traditional boiler principles. Aside from complying with standard technical specifications, the SGS3 system is designed to carry high bankability potential. This state-of-the-art boiler technology eliminates leakages and thereby reduces downtime throughout the lifetime of the system, which is backed by a 5 years non-leakage guarantee. By reducing downtime - productivity, electricity earning and the general payback time of the power plant are greatly improved. The SGS3 line is further optimised to guarantee a high gradient of up to 9°C/min, allowing a rapid ramp-up every morning and after transient clouds. This can ensure more than 30 minutes extra operation on a normal 9 hour day, thereby increasing energy production by 5% and increasing daily revenue accordingly. These two main design elements together reduce LCOE of CSP plants by at least 5%, but in some cases up to 10%.
Feedback from Cargo Power and Infrastructure Ltd.
"Choosing a system with a minimal downtime is of great importance to us, making sure that we can provide as much environmentally friendly electricity from the CSP plant as possible. Therefore, we have chosen Aalborg CSP as supplier of the steam generators for the CSP plant. Aalborg CSP's experience within the CSP industry as well as their great expertise with boiler technology have resulted in a steam generator design that has taken long term savings related to a minimal downtime into account which has a positive impact on the plants bankability" says Mr. Dhruv Batra, Director of Cargo Power and Infrastructure Ltd.
The project is under construction and is expected to start commercial operation in 2015.
Scope of supply:
- Evaporator incl. steam drum
