Meeting today’s energy demands is incredibly challenging. Consumers are demanding more sustainable, environmentally-friendly alternatives, and their energy use patterns are significantly different than just a few years ago.

Utilities are charged with providing safe, reliable and cost effective energy to their communities – yet they face some serious challenges ahead such as:

  1. Significant infrastructure upgrades required without raising rates
  2. Incorporating new technologies and alternative generation options into the mix while maintaining reliability
  3. Continuing to satisfy peak energy demands in a highly regulated industry

To meet their challenges, utilities need options that can make a dramatic impact on cost savings or efficiencies without sacrificing reliability, compromising safety or requiring major operational changes and capital investments. Utilizing Cargill dielectric fluids is one of those options.
