Commencement for
"Smart Community Project in Greater Manchester, UK"

Tokyo, March 13, 2014 - Hitachi, Ltd. (TSE:6501/"Hitachi"), Daikin Industries, Ltd. (TSE:6367/"Daikin"), and Mizuho Bank, Ltd. ("Mizuho Bank") today announced that their consortium will commence the demonstration phase of the "Smart Community Project in Greater Manchester, UK." This project has been spearheaded by Japan's New Energy Development Organization ("NEDO"), with the consortium selected to execute the project.

The project has been planned based on a feasibility study implemented from June to the end of December 2013. The project will now move to a three-year demonstration phase running from April 2014 to the end of March 2017.

The project will see the delivery of Japanese cutting-edge technologies including heat pumps and ICT systems that will help to transform energy usage in the UK, and will demonstrate the use of technologies and systems that will contribute to the UK's transition to a low carbon society. As part of the feasibility study conducted from June to December 2013, the consortium conducted activities including the investigation of UK energy systems, and regulations, interviews of stakeholders including social housing corporations, and power distributors; and joint studies with local stakeholders. Accordingly, it has decided to commence the demonstration phase from April 2014.

In the demonstration phase, traditional gas-fired boilers of heating facilities in social housing will be replaced with electrical or hybrid heat-pumps, and an aggregation system*1 will be introduced to control the heat pumps in each social housing property. This will facilitate coordination of the electricity usage at each property. At the same time, the consortium will aggregate the coordinated electrical power and investigate the capacity to balance the power supply-demand dynamics of residential power users. Furthermore, hot water tanks will be installed with the heat pumps and residential heat retention functions to assess the impact on the capacity, thereby evaluating the feasibility of Demand Response (DR)*2. Through these activities, the aim is to demonstrate the feasibility of aggregation systems and establish the Electricity Aggregation Business Model for the residential sector.

Further details of the project as well as background information about the four participating companies can be found below.

Theme 1. Demonstration of usability and efficiency of load-balancing aggregation technology and systems for residential power consumption

(1) Installation of heat-pumps (Daikin)

In this demonstration, about 600 electrical and gas hybrid heat pumps will be installed in social housing properties with high thermal insulation as load-balancing capacity. During the feasibility study, it was confirmed via simulation that fuel cost might decrease when existing gas-fired boilers are replaced with electrical heat pumps under controlled conditions.

(2) Development of the aggregation system (Hitachi, Daikin)

This project will develop an aggregation system consisting of two functions: heat pump aggregation functions, which balance the load of the heat pumps; and electrical power aggregation functions, which aggregate the load-balancing capacity from the heat pumps for trading in the electricity trading markets.

The heat pump aggregation functions provide the load-balancing capacity from heat pump groups by remotely controlling heat pumps, while maintaining consumers' comfort. Through these functions, the project will evaluate the impact of external factors such as home thermal insulation properties, and consumer attributes such as family structure and lifestyle patterns, on power consumption and the balancing of power supply-demand dynamics.

The electrical power aggregation functions aggregate the load-balancing capacity from heat pumps for trading in the electricity trading market or with electricity traders bilaterally. The demonstration will develop a system to coordinate the project with existing aggregators, and will use pseudo trading, which does not require payments between the parties.

(3) Establishment of ICT systems*3 (Hitachi)

The ICT systems have functional structures that can realize the aggregation functionalities and meet UK security and telecommunication standards. Hitachi will also develop and evaluate the real-time data processing, reliability, and scalability of the ICT system.

Theme 2. Establishment of Business Model (to be demonstrated by Mizuho Bank, Daikin, Hitachi)

The feasibility study, proposed schemes which enable win-win relationships between electricity trading market participants, heat pump vendors and power aggregators in the UK, based on the assumed market penetration curve for heat pumps. Looking ahead, during or after the demonstration, the consortium will investigate the Electricity Aggregation Business Model using heat pumps, and set out to popularize and expand the heat pump aggregation business. Furthermore, a scenario for popularizing heat pumps will be proposed, alongside public policies that support this goal.

Aggregation system: This system balances electrical power supply and demand by aggregating electrical power coordinated from a diverse array of sources, from home appliances including residential facilities, to rechargeable batteries on board electric vehicles (EVs), and industrial power generators.
Demand Response: Demand response refers to changes in electricity consumption by end-use consumers from their normal consumption patterns in response to incentives designed to reduce power consumption during times of peak electricity demand, etc.
ICT systems: Information and communication technology systems that integrate information and control functions so as to achieve smart and efficient social infrastructure.
