Seattle City Light Increases Power Factor Penalty

Facilities served by Seattle City Light have a new target when it comes to using power effectively.  As of January 1st, 2014, all consumers whose power factor falls below .97 will be charged $.15/kVarh.  This is an increase from the previous target of .95 and one of the highest in the nation.

Power factor is the ratio of working power to apparent power and measures how effectively power is being used.  Low power factor has a number of implications, in addition to charges from utilities.  It can reduce total system capacity, voltage and efficient use of power.

To counteract low power factor, a variety of solutions have been employed.  The most commonly known is the introduction of power factor correction capacitors.  However, it is generally encouraged to develop a power study to understand the causes and the expected benefits of solutions.

Retrofit Panelboards Save Significant Construction Costs


A healthcare facility located in the Puget Sound region was faced with significant construction costs as a change in their main service  increased the fault current above the ratings of some legacy panelboards.  Some panelboards were embedded in concrete and to swap them out could have meant serious structural changes.  To make the situation more difficult, not any circuit breakers would solve the situation as selective coordination needed to be maintained for this hospital.

GE Introduces New TLE Series UPS with Industry-Leading Efficiency and High Output Power

To meet the growing power needs of mission-critical facilities, GE (NYSE: GE) today introduced its new TLE Series uninterruptible power supply (UPS) global platform. The TLE Series transformer-less, three-phase UPS applies GE’s innovative technology to provide facilities with best-in-class operating efficiencies – up to 97 percent efficiency in double-conversion mode and up to 99 percent in eBoost, also known as multi-mode , operation. By operating at such high efficiencies, the TLE platform helps lower system operating expenses and power usage effectiveness (PUE). In addition, the TLE Series delivers clean power quality, including low-input harmonics, high-input power factor and low-output voltage distortion, to the critical loads.

GE’s TLE Series provides mission-critical facilities such as data centers, healthcare facilities and financial institutions with the broadest range of double-conversion output power available in the industry today – ranging up to 1.5 megawatts (MW) in a single module. To meet customers’ reliability, efficiency and power demands worldwide, the TLE Series is offered in both UL and CE versions. The CE version spans up to 1.2 MW, while the UL version ranges up to 1.5 MW. The TLE 160-kilowatt (kW) to 400-kW, CE-rated products are available now; and the UL-rated products will be available throughout 2013 with the higher power ranges available in 2014.

The platform offers an unprecedented level of power density, a measure of the amount of power output compared to the product’s size or footprint, which reduces the overall capital expense of installation. The small footprint makes the TLE ideal for both new construction and retrofit applications where space optimization is a priority.
