Energy Improvement Districts Promote Common Sense Ingenuity

Many of the digital age companies that drive economic development and job growth now realize the true cost of electric power has two components. First, utility bills are escalating by 40 to 100 percent in most major cities due to fuel price increases and charges for upgrading badly deteriorated transmission lines. More importantly, the cost of business interruption and equipment damage due to power fluctuations and outages is particularly high or even life threatening. Hospitals, emergency response teams, sewage treatment plants, biotechnology research centers, financial trading floors, and hotels are all feeling the simultaneous impact of increasing costs and deteriorating power quality.
