Retrofitting power plants with solar technology
EPRI is partnering with the Tri-State Generation and Transmission Assn. Inc., Progress Energy, and Southern Co. on the study, Solar Augmented Steam Cycles for Coal Plants.
Case study analyses will be performed by WorleyParsons Group Inc.
This and the first project (a study launched in October at natural-gas facilities) both involve adding steam generated by a solar thermal field to a conventional fossil fuel-powered steam cycle, in order to offset some of the fuel required to generate electric power. As part of the coal project, case studies will be conducted at Tri-StateÂ’s 245-MW Escalante Generating Station in Prewitt, N.M.; and at Progress EnergyÂ’s 742-MW Mayo Plant in Roxboro, N.C.
The projects will provide a conceptual design study and two detailed case studies. The goal is to analyze design options to retrofit existing plants, and identify options for new plant designs.

Switch from fossil fuels to electricity could cost $1.4 trillion, Canadian Gas Association warns
TORONTO - The Canadian Gas Association says building renewable electricity capacity to replace just half of Canada's current fossil fuel-generated energy could increase national costs by as much as $1.4 trillion over the next 30 years.
In a report, it contends that growing electricity's contribution to Canada's energy mix from its current 19 per cent to about 60 per cent will require an expansion from 141 gigawatts today to between 278 and 422 GW of renewable wind, solar and storage capacity by 2050.
It says that will increase national energy costs by between $580 billion and $1.4 trillion between 2020…
