NIALM in industry
Since the Pittsburgh workshop I've learnt a lot about industry's perspective of NIALM. Academic work is often criticised for solving simplified problems, and I believe it's important to understand what our friends in industry believe to be the real-world problems. This post is meant to list the companies I'm aware of that are working in this field, and summarise their approach to energy disaggregation. As always, please leave a comment or drop me an email if you know of any inaccuracies or omissions.
Powersavvy is a company looking to highlight energy savings to both households and businesses. They offer their own meter, which can be installed for either 6 days or indefinitely, and is used to provide disaggregated advice based on the data they collect. Their website quotes that savings of 30% can be easily achieved using their products.
Sense are a consumer-oriented startup based in Cambridge, Massachusetts, doing sub-second level monitoring of current and voltage through 2 current sensors attached to the service mains in the electric panel. On 01.09.16 Sense received $14M in series A funding to grow the business.
Watt-IS are an analytics company which aim to disaggregate smart meter data collected by utilities to produce appliance-level energy consumption data and actionable feedback which could be provided to customers. Such feedback includes the potential savings from replacing a refrigerator, reducing the whole-home standby power, and also shifting demand to off-peak times.
Wattics is a software company, partnered with EpiSensor, who have previously provided disaggregated appliance level data from a single point of measurement. Their on-line dashboard identified unneeded or deteriorating appliances and suggested energy saving measures. However, Wattics not longer offer disaggregation functionality.
Watty is a startup company closely linked with the KTH Royal Institute of Technology. Rather than focusing specifically on energy disaggregation, Watty is an energy analytics company that focuses on producing the insight required to save energy and money for specific buildings.
