Study and Report on CT Purge Credits

Key Research Question Increased use of non-dispatchable renewables continues to require more flexible operations of many generation assets. Changes in fuel costs, and environmental regulations also contribute to this trend. Increased flexible operations often manifests as faster startup and more frequent startup. NFPA-85 has historically required the gas turbine to crank at high-speed prior to...

Turbine Generator Maintenance Intervals: Industry Trends and Practice

Continued pressure for cost reductions at power generation facilities has increased the focus on maintenance intervals for large systems such as steam turbines and generators. These system overhauls are major cost-drivers, requiring weeks of unit shutdown and significant contracted and internal resources. The overhaul scope is generally open-inspect-close, with a range of planned maintenance tasks...

Flexible Operation of Hydropower Assets

With continued deployment of variable solar and wind generation, hydropower will play an increasingly important role in system load balancing, regulation and storage. Hydropower can provide excellent response to variable demand requirements, as evidenced by pumped-storage projects. Wear and tear acceleration associated with more frequent flexible deployment of aging hydropower assets, however, will increase. Accelerated...

Reciprocating Internal Combustion Engines (RICE) Interest Group

  RICE are growing in importance in the power generation space due to their flexibility, high efficiency throughout their load range, ability to use multiple fuels, and low cost. RICE are potential good fits for ancillary services and to match up with intermittent renewables, and are also being considered for more baseload operations in certain...

Superheater Outlet Header: Validation of Fitness for Service Methodologies

This project will conduct a Root Cause Analysis (RCA) for an ex-service header which, based on previous inspection, has been retired due to the extent of damage present. The project will investigate the link between operation, materials properties, NDE and damage, and provide valuable feedback for options to minimize damage on similar components. An RCA...
