［USA］Recent ACEE Report Finds Most Utilities Aren't Getting Full Value from Smart Meters

According to a report released by the American Council for an Energy-Efficient Economy (ACEEE) on January 9, 2020, most utilities are missing the opportunity to utilize advanced metering infrastructure (AMI) to help customers conserve energy.[1] AMI has grown rapidly in the past decade, now accounting for nearly half of all meters in the U.S. At the end of 2019, there were 98 million smart meters deployed by utilities and by the end of 2020, that number could reach 107 million.[2] However, ACEEE found that these smart meters are being underutilized by utilities; of the 52 utilities ACEEE surveyed, only one, Portland General Electric (PGE), was found to use smart meters to their fullest potential. PGE taps into all six use cases ACEEE identifies for applying API data: time of use rates, real-time energy use feedback for customers, behavior-based programs, data disaggregation, grid-interactive efficient buildings, and conservation voltage reduction.

These use cases leverage AMI data by pairing it with customer engagement tools, pricing strategies, and programs that support customer action. A failure to optimize AMI investments can lead to regulators denying future grid modernization efforts. In 2019, for example, Virginia regulators rejected Dominion Energy’s proposal for a smart meter deployment.

[USA] “Portland General Electric’s Ambitious Smart Grid Test Bed Launches”

[Portland General Electric, 15 July 2019]

Portland General Electric (PGE) has launched its latest venture into new and innovative technologies, the Smart Grid Test Bed. The Test Bed aims to “integrate smart grid technology on a scale never before attempted in the United States.” The project will cover three neighborhoods in its service territory – and over 20,000 of their customers will be able to participate in the demand response programs involved with the test bed; they will also be able to receive incentives for using smart-home technologies. The pilot will also help boost the development of distributed energy resources like rooftop solar, batteries, thermostats, water heaters, and EV charging.  PGE hopes this project will be a major step in creating a virtual power plant and “will help address climate change, empower communities in how they consume energy and create a more resilient power system, all while saving customers money.”

[Japan] Toyota Tsusho and Chubu Electric Power Launch Vehicles-to-Grid Demonstration Tests in Toyota City, Aichi Prefecture

Chubu Electric Power and Toyota Tsusho jointly announced on November 7, 2018 that they will launch Vehicle-to-Grid (V2G) demonstration tests in Toyota City, Aichi Prefecture, from November 14 to 16 and December 12 to 14, respectively. The tests will validate the effectiveness of value-added services such as battery charging and discharging, examine how the V2G system will balance the supply and demand of electricity, and study the impacts of V2G on power grids.

Renewable energy sources such as solar and wind energy have been increasingly deployed worldwide, but challenges remain in managing the fluctuation of renewable energy output and surplus power generation. In order to utilize the excess energy, Toyota and the U.S.-based Nuvve Corporation have collaborated to design the V2G system. The design aims to control the power supply and demand, storing surplus power in Electric Vehicles (EVs)/Plug-in-Hybrids (PHVs) and later discharging it back to the power grid. Chubu Electric Power and Toyota plan to submit a report with the project’s results to a Japanese regulator, the Agency for Natural Resources and Energy, by February 2019.

[USA] “National Grid Expands Partnership with AutoGrid in Series D Investment”

[AutoGrid, 14 November 2018]

On November 14, National Grid Partners and AutoGrid, a data analytics startup, announced their latest partnership and direct investment agreement to develop “advanced applications of artificial intelligence (AI)-driven optimization, enabling predictive control of grid-edge assets.” This partnership is based off of AutoGrid’s $32 million Series D investment round. Lisa Lambert, Chief Technology and Innovation Officer at National Grid and the Senior Vice President of National Grid Partners, stated “They have one of the best utility-focused AI teams in Silicon Valley, and we believe there is a tremendous market opportunity for them to grow rapidly over the next few years. We are also actively engaging AutoGrid to help meet our strategic objectives in the grid analytics category." AutoGrid is one of our first direct investments.  As a side note, this is not the only partnership National Grid has with AutoGrid; the two have a gas demand-response pilot in New York.

[Japan] Kansai Electric Power Initiated a Demonstration Test of a Low Power Wide Area Wireless Child Safety Service in Omachi City, Nagano Prefecture

On October 1, 2018, Kansai Electric Power announced a partnership with K-Opticom, Omachi City of Nagano Prefecture, and the Omachi City Board of Education to launch a demonstration test of a child safety service, which will use a Low Power Wide Area (LPWA) wireless network to monitor the location of children in Omachi city, Nagano prefecture. To reduce the costs of the service, the system is built on LPWA wireless technology with long-range (LoRa) communication technology, which enables long-range communication using low electricity consumption. The system will be installed at base stations serving other services to further reduce the costs.

The service will notify guardians when children enter or exit from the designated geographic area, in order to ensure the safety of children during their school commute. In order to protect the children’s privacy, the service will identify their location based on fixed areas, rather than his or her exact location. The test will evaluate the user experiences, particularly guardians’ experiences using the service by smartphone, and will identify technical issues.[1]

Kansai Electric Power hopes to strengthen its relationship with local communities through this new initiative.

[Japan] Tohoku Electric Power Launched Customer-Assisted Smarter Project for Monitoring Newly Developed Services

Tohoku Electric Power announced on July 11, 2018 that it has launched a Customer-Assisted Smarter Project, which aims to monitor and verify the effectiveness of new services to ensure comfortable and convenient lifestyles for customers. By using information technologies such as IoT, AI, and communication robots, the project will verify the feasibility and user-friendliness of two newly-developed services: the lifestyle assistance communication robot BOCCO, and a service for providing advice on how to save energy when using home appliances. The project is scheduled to be carried out from July 11, 2018, to the end of August 2019 and the utility is looking for 170 participants to be monitored as part of the project.

The BOCCO robot will demonstrate its multiple remote-control functions, such as helping family members to monitor the current conditions in a house and notify them via smartphones, turning the air conditioner on/off from outside through the devices, and automatically controlling the air conditioning system in a house by predicting the optimal air conditioning operating time, based on weather information and the current temperature and humidity in the room. Separately, the project will also monitor the effectiveness of a service providing consumers with emails or SNS messages with energy-saving advice for home appliances. The service advises customers on how to use home appliances to save energy and reduce costs, based on an electricity usage prediction system that has been jointly developed by Tohoku Electric Power and Mitsubishi Electric, using data collected from smart meters.
