Solar Thermal Hybrid Systems
WorleyParsons Capabilities WorleyParsons helps our customers integrate solar thermal power with power generation assets to deliver high-value, sustainable power: • Gas Turbine Combined Cycle • Coal-fired • Waste-to-Energy • Biomass • Geothermal • Desalination • Enhanced oil recovery applications

Integrating Solar for Increased Economic and Environmental Sustainability
WorleyParsons provides solar energy as a solution to increase economical and environmental value of both existing and new fossil based assets. Hybridizing concentrated solar power (CSP) with conventional power generation technology can provide high-value, dispatchable power.

Applications and Benefits
Combining solar thermal energy with traditional power generation plants can develop a number of key benefits: • Solar thermal energy can be converted to electric energy at higher efficiencies than in stand-alone CSP plants • Incremental costs of a larger steam turbine generator and associated balance of plant equipment needed for a hybrid plant are less than a stand-alone CSP • Daily start-up and shutdown energy losses can be eliminated and reduce overall costs • Incremental operational and maintenance (O&M) costs incurred for a solar addition are lower than stand-alone CSP O&M costs WorleyParsons provides a full range of services to support the development of both new and retrofit solar hybrid systems. Our staff provides assistance from planning and benefits analysis, to project management, execution and plant operations. Our full service engineering ensures successful completion and operation of sustainable assets.

WorleyParsons worked across the three project phases; • Feasibility/optimisation • Detailed design • Monitoring Medicine Hat is installing a 1 MW Integrated Solar Combined Cycle (ISCC) project at their existing 4x2 combined cycle facility. The project will demonstrate a unique application of Concentrating Solar Power (CSP) at high latitude, with the goal of demonstrating the feasibility of CSP in Canada. The Phase 1 engineering feasibility/optimisation study was completed on time and within budget, receiving all regulatory approvals from local commissions.

We analysed reliability, O&M, regulatory, and permitting considerations to provide an optimised design recommendation. A comprehensive guideline manual was developed for integrating solar thermal energy into two existing modern natural gas–combined cycle plants: the 570 MW Griffith Energy Facility and the 1,000 MW Chuck Lenzie Generating. The analyses included all of the considerations needed to evaluate, select, and execute an ISCC project, including: • Site and plant condition evaluations • Thermal cycle and performance optimisations • Capital, operating, and maintenance costs

The solar thermal installation at Kogan Creek Power Station generates steam from solar energy capable of boosting the output of the 750 MW coal-fired super-critical unit at Kogan Creek by a further 44 MW. The heat input to the steam is provided by Compact Linear Fresnel Reflector arrays arranged into 14 individual solar steam generators. WorleyParsons evaluated means for utilising the solar energy, engineered the solution for integrating the solar steam, and assisted in the implementation of the project. By utilising solar energy for boosting the output of the unit, we achieved increased electrical output with no increase in greenhouse gas emissions.
