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.

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.

Stick-Built or Modular Design for Power Plant Projects? Actually, Both.

More than 10 years ago, power plants were traditionally stick-built, with each building custom designed and made for that particular plant. The major benefits of this approach were maintenance access and lowest equipment pricing, since a substantial portion of the work was being completed in the field.

Fast forward a few years and three factors started instigating a change in philosophy: centralized organizations, rising construction costs and real estate issues.

 
 

Supporting the Use of Renewable Energy with Consistent Inlet Air Temperature

The changes in U.S. electricity supply and usage levels are rapidly reshaping utility load profiles and thus generation and transmission requirements for both new and existing resources.

The recent discovery of relatively cheap natural gas in the U.S. and growing use of the fuel as a baseload power generation source has also coincided with the rapid adoption of renewable resources in many parts of the U.S.  These new components of the electricity supply stack continue to displace more traditional and older forms of baseload power generation, coal and nuclear units, for both economic and public policy motivations.  Unfortunately, these growing pieces of the U.S. generation supply side all are subject to weather related intermittency.
