Seven Tips for Maximizing the Performance of your Chilled Water Plant

Chilled water plants are sophisticated assets comprised of mechanical and electrical systems controlled by programmable logic controllers (PLCs).  They play a critical role in the operation of a wide range of facilities, including power plants, industrial facilities and data centers, and are often designed to function with minimal operator interaction. However, even the most intelligent systems degrade over time and require some amount of service and tuning to maintain optimal performance.

Here are some preventative maintenance measures you can take to ensure that your chilled water system is always operating in an efficient, safe and reliable manner while maintaining peak performance.

Addressing Electrical Space Requirements in Modular Energy Plant Design

“Sure, we have plenty of space….”

Often times that is the response we receive when we have to add equipment to an existing, or nearly complete design.  While there may be physical space for the equipment in question, the space requirements imposed by the National Electrical Code or other regulations around electrical equipment often make a seemingly ample-sized space just too small.  Some reasons for regulatory requirements for space around electrical and other equipment include: means of egress from an enclosed space in the event of a fire, door swing clearance for protection of personnel, electrical working clearances for the protection of electrical workers, fire safety equipment access (such as fire extinguishers), and equipment operational space where manual manipulation of equipment is necessary for operations personnel.

The Advancement of Control Technology for Power Augmentation Systems

In a day and age when technology is advancing more rapidly than ever before, the success of manufacturers and power plant owners has become increasingly reliant on facilities’ ability to execute changes quickly, efficiently, and cost-effectively.

This is particularly true in the process control realm, where a significant increase in both the number of solutions available on the marketplace, along with the capabilities they offer, has provided plant operators with the opportunity to continuously optimize their operations at a relatively low cost.

The Benefits of Combining Thermal Energy Storage with Turbine Inlet Air Chilling

In recent years, turbine inlet air chilling (TIAC) has become a highly reliable method of enhancing power plant performance by increasing the output and efficiency of combustion turbines during periods of high ambient temperature. This is typically achieved either through mechanical or absorption chilling and involves supplying chilled water (or an alternative fluid) to the heat exchanger in the filter house of the combustion turbine, thereby cooling the inlet air which raises its density and increases mass flow rate through the compressor.

Not Just More Megawatts, Better Megawatts: The Case for Combined Cycle Output Augmentation in a Low Power Price Environment

Currently, the fragmented U.S. wholesale power markets do not face a scarcity of megawatts, as evidenced by the North American Electric Reliability Corporation’s (NERC) recent Summer Reliability Assessment and reported by Public Power Daily here.

However, this does not suggest turbine inlet air chilling (TIAC) is not a valuable resource for U.S. power generators.  TIAC quickly elevates a combined cycle unit’s productive capacity during challenging ambient conditions. The benefits of the additional megawatts produced from low-heat rate/low-cost generation resources may be evaluated on a relative (better) or absolute (more) basis.
