Quick Take: Competitions and crowdsourcing are the rage almost everywhere these days, so why not in the smart grid? As you'll read below, the Department of Energy has hired one of our national laboratories to run a contest to develop better, cheaper wireless sub-meters.
The laboratory in question, Pacific Northwest National Laboratory, has previously administered a successful prize for solid-state lighting. The goal of the new challenge is to encourage a cost-effective, standards-compliant wireless sub-metering system. it must measure electrical energy at various locations in a building and send them wirelessly to a data collection point within the building complex. I think smart manufacturers will want to participate. And both manufacturers and customers will want to study the winning design closely. - By Jesse Berst
Low-cost Wireless Meter Challenge
The performance specification for the Wireless Metering Challenge is now available. The goal of the challenge is to develop a wireless metering system that contains the following attributes:
DOE has presented a summary of the challenge. View the slides from this presentation.
Why a Metering Challenge?
The oft-used adage "If you can't measure it, you can't manage it" is true in commercial buildings, where reducing energy can be enabled by the collection and use of data. While it is technically possible to get (near) real-time, granular energy use data for even the most complex building, many decision makers do not have that information, as the high cost of purchasing and installing additional meters is prohibitive. This is particularly critical in jurisdictions where metering of building energy use is required by law, such as the federal sector and a growing number of markets like New York City. The market is in need of reliable, cost-effective metering systems.
In order to take action to reduce energy usage, owners and operators need to know how energy is being used in their buildings. Metering data provides visibility to a building's energy use. Energy costs can be reduced by taking action to resolve problems identified by examining metered data. While metering systems do not directly improve energy efficiency, metering systems enable focused, energy efficient actions. It is estimated that using systems results in energy efficient actions that deliver electricity energy savings of at least 2%.
Today, the cost of building panel-level metering systems is typically the key hurdle to implementing these technologies. DOE has a proven track record through its Rooftop Unit Challenge of teaming up with industry to solve problems related to technology development. In this case, demand-side interest from commercial sector actors will form a compelling incentive to manufacturers to provide low cost, reliable metering devices. Manufacturers will see benefits from DOE raising awareness about the need for metering by working with BBA members and other stake holders to implement technologies. DOE will also provide technical assistance in the form of 3rd party verification and testing of the Challenge technologies. DOE can then drive the implementation of electric metering through lower pricing and a greater understanding of the performance of the technologies.
The final specification is now available for review below.
US Energy Secretary Moniz will be announcing the Challenge participants from both the manufacturing and building owner/procurement community the first week of June.
