It will require
2. manufacturers to design new products, adopt new standards and completely re-design their approach topower delivery systems. It must also be determined where a dc power system will completely replacethe existing ac architecture and where the deployment of dc power delivery systems as part of a ac-dchybrid architecture would be appropriate. Despite the challenges, the addition of dc power deliverysystems offers the potential for improvements in energy efficiency, reliability, flexibility, power qualityand cost of operation as compared to traditional power systems.The Darnell Group identified the potential market for dc power solutions in four specific sectors: datacenters, commercial/industrial facilities, residential installations and telecom central offices. For eachsector an analysis identifying two key market penetration rates of adoption for dc power was used. Thefirst is the “threshold” rate of market penetration required for dc technology to achieve in each sector inorder to continue expanding. The second penetration rate is the “saturation” rate, which represents thepercentage of the market the technology expects to eventually capture in order to be consideredmainstream. Once these market penetration rates are determined, a high level estimate of the dollarmarket for dc power systems and components for each sector covered will be presented.This analysis was applied to each of the four areas covered in this report. Each area recorded a distinctthreshold and saturation rate based on key market drivers specific to each industry. Two areas ofimmediate opportunity for the adoption of dc power are projected to be in the data center andcommercial/industrial facilities segments. Both of these sectors are projected to reach their adoptionstages by 2019. These facilities each have the advantages of strong standards activity, supportinggovernment regulations, and a number of demonstration facilities. In addition, a small but growingnumber 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 reacha higher market saturation rate for adoption. The market drivers for this segment are much differentthan the other applications mentioned. Telecom central offices are already dc facilities and thetechnological, regulatory and economic factors needed for them to adopt a higher-voltage dcarchitecture, in addition to their current 48Vdc configuration, must be more compelling. In light of theeventual adoption of ETSI EN 300-132-3, there are a number of strong arguments for this industry toadopt an architecture combining both low and high voltage dc power, as well as a hybrid dc powerarchitecture, combining 48Vdc for existing telecom equipment and higher-voltage dc for additionaldatacom equipment.The residential dc industry is in a much earlier stage of development than the other industries covered inthis report. Despite the trend towards zero net energy (ZNE), this sector does not have an established setof standards or any large bodies or organizations actively promoting technology or products. (A ZNEbuilding is defined as one that produces as much energy as it uses in a year.) As a result, both thethreshold and saturation rates are quite high. However, there are a number of factors, including the largePV market and several government mandated programs that may provide the industry with a significantpush.A ZNE building could significantly cut dependence on fossil-based energy and supply the required energy
3. through on-site distributed generation, such as solar, wind, fuel cells, or microturbines. A market isalready emerging for zero energy buildings today, but it remains a small fraction of the overall buildingconstruction industry. However, a number of government initiatives designed to encourage developmenthave been enacted.In fact, in 2008 the California Public Utilities Commission introduced the state’s Zero Net Energy ActionPlan for Buildings. Updated in 2011, the plan calls for all new residential construction in California to bezero net energy or equivalent to zero net energy by 2020. The same applies to commercial developmentsby 2030. (Equivalency allows the goal to be applicable to all buildings –even those unable to produce allnet energy needs on site.) This will require an intense focus on reducing energy consumption throughstate-of-the-art design and technology, with grid-connected renewable energy to minimize eachbuilding’s residual carbon footprint.As an emerging technology, the further development of dc power is highly reliant on the adoption ofstandards and regulations. At the lower power level, the EMerge Alliance has concentrated on thedevelopment of a 24Vdc standard for commercial, industrial and residential buildings. The EMergeAlliance Standard 1.0 regarding 24Vdc power creates an integrated, open platform for power, interiorinfrastructures, controls and a wide variety of peripheral devices to facilitate the hybrid use of ac and dcpower within buildings.In cooperation with other industry associations and standards-making bodies, the EMerge Alliancestarted working on a dc power standard for data center facilities in 2009. The selection of 380Vdc as thedistribution voltage is based on the agreement of engineering data from a number of organizations inthe United States, Europe, and Japan. In addition, EPRI developed the first dc voltage tolerance envelopeplotting voltage variations versus time for 380Vdc powered equipment. The new dc voltage toleranceenvelope provides the technical details of the electrical operating environment, including allowablevoltage surges and sags that could enable engineers to design power converters for use with 380Vdcdistribution systems for next-generation data center equipment.This standard is being developed in parallel to an effort taking place with the EuropeanTelecommunications Standards Institute (ETSI), and is expected to be in harmony with ETSI EN 300 132-3. It will address the problem of compatibility between the power supply equipment and bothdatacom/telecom equipment and to the different load units connected to the same interface. Theeventual adoption of EN 300-132-3 poses both an opportunity and a challenge to the advocates ofhigher-voltage dc power in telecom central office facilities, as it allows equipment designed to thisstandard to be powered by either high voltage ac, single or three phase rectified ac, or dc current.A dc microgrid is an emerging concept that could gain traction as other emerging technologies becomemore established. Defined by the Department of Energy as a group of interconnected loads anddistributed energy resources within clearly defined electrical boundaries that act as a single controllableentity with respect to the grid, these microgrids are expected to play an important role in thedevelopment of dc power. In fact, a number of companies are already offering products to support thedc microgrid concept.
4. The implementation of a system that allows the delivery of dc power to a microgrid has the potential toprovide a facility with a number of advantages, such providing reliability and power quality. In addition,as renewable energy technologies such as solar PV become more widespread, the development and useof a dc microgrid could evolve into a cheaper and more efficient alternative. A possible course of actionis to install a dc network linking dc devices to dc power supplies.The development of products and power supplies designed to work in a dc power environment is criticalto the further expansion of dc power. Although power supplies and components for data centers arecurrently designed specifically for demonstration facilities and not widely available as standard products,a number of prominent companies are starting to see the potential of introducing dc power to datacenter facilities. Delta Electronics recently launched a state-of-the-art data center dc power solution thatincludes a complete product portfolio of dc UPS systems, power distribution units (PDUs), and serverpower supplies for more energy-efficient data center applications.Additional factors contributing to the advancement of dc power include the large consumer electronicsmarket, which operates exclusively on dc power and currently requires conversion from ac sources.These devices are common in every household and include televisions, set-top boxes and many others.In aggregate, the millions of conversions performed for the operation of these electronic devices extracta huge loss in energy during conversion and therefore represent a long-term opportunity.Although dc power is still an emerging industry, it is already providing opportunities for a number ofindustries and applications. In this report over 35 illustrations are presented depicting a variety of powersystem schematics and comparisons, architectural standards, efficiency standards and other relevantinformation. The focus of this comprehensive analysis provides decision makers with an insightful lookinto the current and future opportunities and threats available in the dc building power supply market.Table of Contents :IntroductionEmerging Trends and DevelopmentsHybrid AC-DC FacilitiesDC MicrogridsZero Net Energy FacilitiesAdditional Applications and DriversLightingConsumer DevicesElectric VehiclesEnergy StorageUninterruptable Power SuppliesVariable Frequency DrivesIntelligent Universal Transformers (IUT)Pending Issues in the Development of DC PowerStandards and Regulations
