The introduction of dc power to industries that traditionally rely on ac power is expected to cause a fundamental shift in how new and existing buildings are designed and operated. It will require manufacturers to design new products, adopt new standards and completely re-design their approach to power delivery systems. It must also be determined where a dc power system will completely replace the existing ac architecture and where the deployment of dc power delivery systems as part of a ac-dc hybrid architecture would be appropriate. Despite the challenges, the addition of dc power delivery systems offers the potential for improvements in energy efficiency, reliability, flexibility, power quality and cost of operation as compared to traditional power systems.
The Darnell Group identified the potential market for dc power solutions in four specific sectors: data centers, commercial/industrial facilities, residential installations and telecom central offices. For each sector an analysis identifying two key market penetration rates of adoption for dc power was used. The first is the “threshold”
This analysis was applied to each of the four areas covered in this report. Each area recorded a distinct threshold and saturation rate based on key market drivers specific to each industry. Two areas of immediate opportunity for the adoption of dc power are projected to be in the data center and commercial/industrial facilities segments. Both of these sectors are projected to reach their adoption stages by 2019. These facilities each have the advantages of strong standards activity, supporting government regulations, and a number of demonstration facilities. In addition, a small but growing number of products have been developed by companies like Delta Electronics, Emerson Network Power, Nextek Power Systems and others.
Although the telecom industry maintains a lower threshold penetration rate, due to its size it must reach a higher market saturation rate for adoption. The market drivers for this segment are much different than the other applications mentioned. Telecom central offices are already dc facilities and the technological, regulatory and economic factors needed for them to adopt a higher-voltage dc architecture, in addition to their current 48Vdc configuration, must be more compelling. In light of the eventual adoption of ETSI EN 300-132-3, there are a number of strong arguments for this industry to adopt an architecture combining both low and high voltage dc power, as well as a hybrid dc power architecture, combining 48Vdc for existing telecom equipment and higher-voltage dc for additional datacom equipment.
The residential dc industry is in a much earlier stage of development than the other industries covered in this report. Despite the trend towards zero net energy (ZNE), this sector does not have an established set of standards or any large bodies or organizations actively promoting technology or products. (A ZNE building is defined as one that produces as much energy as it uses in a year.) As a result, both the threshold and saturation rates are quite high. However, there are a number of factors, including the large PV market and several government mandated programs that may provide the industry with a significant push.
