Gujarat Solar One plant receives steam generation unit from Aalborg CSP

Aalborg CSP has announced it has shipped a new steam generation unit to India, this time is for the Gujarat Solar One plant in India.


The plant is a 25 MW parabolic trough facility with up to 9 hours of thermal energy storage with molten salts, promoted by India's Cargo Power & Infrastructured being built near Rapar, in the state of Gujarat, and is being built by Lauren Engineers & Constructors as the EPC contractor. The plant is scheduled to be operational by 3rd quarter of 2013.

The steam generator, designed and delivered by Aalborg CSP, consists of one steam generating heat exchanger line with one economizer, one evaporator, one superheater and two reheaters. The steam generator unit is on the water/steam side based on natural circulation and on the heat transfer fluid (HTF) side based on forced circulation. The heat exchanging technology is based on shell and tube heat exchangers with coil and header design.

“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 Aalborg CSP steam generatorAalborg CSP's steam generator design is a 100% welded coil and header-type based on steam boiler technology, rather than conventional kettle-type heat exchangers. Applying a fully welded coil and header-type with up to 4.5mm thick tubes significantly reduces leaking tubes and thereby reduces downtime throughout the lifetime of the system. By reducing downtime both productivity, electricity earning and the general payback time of the power plant are greatly improved.

Aalborg CSP experienceWith a solid experience from the CSP industry in Europe, Aalborg CSP received at the end of 2011 the first order for a 50MWe steam generator system of coil and header-type for the Godawari Green Energy CSP plant in India. This steam generating system has just been handed over for installation and the plant is set to start operation by 2nd Quarter of 2013.

As reference Aalborg CSP has designed and delivered steam generator systems for five 50MWe CSP plants in Spain as well as solar tower receivers for three projects with an output up to 20MWe.Moreover Aalborg CSP has worked on several research and development projects regarding storage opportunities as well as optimization of both steam generator design for parabolic trough plants and receiver design for solar towers.

As part of the plan to achieve a strong market position on the Indian market The Delta Group, a group of companies focused on the power sector, has been appointed as a local partner.
