12 Rokkasho Village Demonstration Project Overview Community Energy Management System (C-EMS) provides an integrated optimization system for mid-size and individual renewable energy generation, community energy storage, and Smart houses including HEMS and Plug-in Hybrid cars. C-EMS helps create a 100% CO 2 -free community. (Commenced Sep. 2010) Power Grid Power Distribution Line -Grid side supply and demand management and control (includes power generation and storage) -Energy service integration -Demand side power generation and storage control (includes HEMS functions) Futamata Wind Power Generation Site (JWD) Inter-connection Point PV(100kW) Photovoltaics (Hitachi) Hub Battery (100 kw) Charge/ Discharge NAS Battery (NGK) Multi family building PCS PCS Smart House (Panasonic) Surveillance and Control Information Exchange Charge/ Discharge Control Automatic Surveillance and Control Server (CEMS Server) Heat Pump Control PHV (Plug-in Hybrid Vehicle), PCS (Power Conditioning System) NAS (Sodium-sulfur battery), JWD (Japan Wind Development Co., Ltd.)

15 UK Smart Grid Case Study LCNF project with WPD LCNF Tier 1 project As DG (Distributed Generation) becomes more common, the Background D-STATCOM growing number of renewable connections to distribution lines is expected to cause voltage fluctuations (specifically high or low voltage) due to the variable power output of the DG. In turn this can affect the efficiency and capacity of the distribution network. Wind Farm 11kv OH line Goals Determine the effectiveness of D-STATCOM as a dynamic voltage control system in rural 11kV networks to address voltage fluctuation. Optimise control by using a D-VQC (Voltage and Reactive Power Control System) to network multiple D-STATCOMs. Scope 2 Strand project, initially 1 D-STATCOM as proof of concept, then 3 additional units as well as a D-VQC server. Expected Benefits Improvement of power quality and mitigation of voltage spikes issues, thereby increasing network stability, efficiency and load capacity in distribution networks. Learning from project will be beneficial for informing DNOs business case for alternative responses to network rebuild. 4 Project Locations Agreed Substation Tentative 15

16 ETI Smart Systems & Heat Programme Overview Launched in April 2012, the focus of the programme is the design, development and demonstration of a first-of-a-kind energy system aligned with the needs of UK consumers in the domestic and small commercial sectors with a particular focus on heat delivery. Hitachi was announced as Programme Associate. There are four key themes: Understanding real mass-market consumer behaviour in order to design and communicate effective service products Providing energy services and integrated products to consumers in domestic and commercial buildings (primarily domestic & retrofit) Space and water heating but including other energy service needs in or connected to buildings Understanding the evolution of the whole energy system out to 2050, including building retrofits and energy distribution choices 16

17 ETI Smart Systems & Heat Programme Overview Budget of 100mil allocated over 5 years, culminating into the demonstration of a first of its kind Smart Energy System in the UK Hitachi is involved in the delivery of several WAs awarded through open competitive tendering: WA1.1 Enabling Technologies WA3.1 Data Management and Overall System Architecture WA5 Consumer Response and Behaviour + other subcontractors Hitachi as Consortium Leader + other subcontractors Hitachi as a Prime Contractor Hitachi as a Sub-contractor 17
