2 Outline of the Kitakyushu Smart Community Creation Project (1) The stage for the project is Higashida, the birthplace of modern industry in Japan. ~From the birthplace of modern industry to the origin of the green revolution~ 3. Overview of the Higashida District (as of March 2013) Area: 120 ha Residents: approx. 1,000 Employment: approx. 6,000 Annual visitors: approx. 10 million 1. Implementing Body Kitakyushu Smart Community Council (77 groups and businesses) 2. Implementation Period & Project Scale FY 2010 to FY 2014 (5 years), 26 projects, JPY 12 bill 4. Overview of the Demonstration Project (ideal image of society) Transform residents and businesses that use energy into prosumers (producers consumers) by installing photovoltaic arrays and other systems Implement demand side self management so that individual and corporate prosumers work with legacy energy providers to manage energy. Introduce dynamic pricing and incentive programs. 1

13 Step 4: Development of Energy Community Designed for/ with Consumers To change the energy structure of the entire area through energy management by consumers responding to dynamic pricing Peak cut effect through DP through DP around 20% Households introducing EMS (with storage batteries) Peak cut effect 49% Change in behavior was seen in some residents. The indicator has come to be left unchecked. I had checked it in the beginning, but came to leave it unchecked by degrees. (Questionnaire survey in summer of 2012) 33.3% JPY 150 charge in winter is particularity felt as a burden. Offices introducing BEMS Peak cut effect 8.8% Offices visualizing energy use Peak cut effect 0.6% 06% Difficult to respond to peak cuts as it hampers business Already working on energy saving initiatives. It was verified that demand during peak time periods decreased among the households and the offices with installed BEMS. Based on the result that the peak cut effect was not seen so much among the offices visualizing energy use, measures for changing energy structure in terms of energy saving were found to be necessary. 12

14 Step 4: Development of Energy Community Designed for/with Consumers Promotion of demonstrations ti Based on the results obtained and challenges identified through demonstration projects, we will propose a new relationship between consumers and the area from the viewpoint of town development. Next, by developing the environment where consumers can work together for the area, we will design a structure where consumers can evolve into prosumers. Evolution as Prosumers Results & challenges Results & challenges Re design Re design and demonstration Demonstration Designing consumers and their roles The first step is to change the energy structure of the entire area through energy management by consumers that respond to dynamic pricing. 13

15 Step 4: Development of Energy Community Designed for/with Consumers Difficult for the offices visualizing energy use to adapt to DP We have already taken energy saving/electricity saving actions and We must put our business first. How high is the potential of the peak cut among the offices visualizing energy use? A scene from Tokoton (Complete) Peak Cut Day Implementation ti of Tokoton kt (Complete) Peak kcut td Day Fixing a date and time, we asked for temporary power savings/energy savings within a scope which does not affect operations. (July 13, 2013, 15:00 16:00: 27 companies participated) Results The effect during the time (max.): 51.0 % (Company A) The amount of power during the time (max.): 41.2 kwh (Company B) Difficult for the offices visualizing energy use to adapt to DP We have already tk taken energy saving/electricity saving i it i actions and We must put our business first. How high is the potential of the peak cut among the offices visualizing energy use? The report on energy saving diagnosis results Promotion of energy saving diagnosis (FY 2013) An energy saving diagnosis was carried out in the offices that expressed an interest, aiming at rediscovering the structures of their buildings and facilities to trigger action to save energy during peak times. [Results] No effect on those offices during the time, however: Energy savings 14.7% compared to 2012 Reduction of more than JPY 20,000 in basic electricity costs 14

16 Step 4: Development of Energy Community Designed for/with Consumers ていたん & ブラックていたん In order for consumers respond to peak times, all stakeholders must understand energy structures, and first and foremost, each consumer and facility must take action to save energy. Data on power demand curves used for explanations Explain the power demand curve measured every 30 minutes by the smart meter to each consumer to visualize energy use. Explain the fee structures and DP to promote awareness. Encourage improvement through modulated use and continuous management of facilities in offices with EMS. Also, call for action other than in energy (reduces copies, etc.) Results from FY 2013 (compared to FY 2012) Thinning of lights, installation of reflection plates: 9.3 % Installation of skylights in factories: 94% 9.4 % Shut off of A/C system on holidays: 8.6 % Results from FY 2014 (compared to FY 2013) Conversion to LED lighting: 32.1 % Same as above: 12.5 % Same as above: 9.5 % Conversion to LVD lighting: 19.1 % Installation of BEMS: 6.0 % 15

18 Step 4: Development of Energy Community Designed for/with Consumers Coexistence with hydrogen energy Byproduct hydrogen gas from factories, storage cells, and PV were prepared as a group around public facilities functioning as evacuation shelters in the event of a disaster. In addition, extended power supply to storage batteries from fuel cell vehicles in disaster situations and storage of surplus electricity it as stored energy through h hydrogen conversion were also demonstrated. Results Disaster response function improved The range of hydrogen use expanded Shopping incentives An examination was made as to whether changing people s behavior would be effective as a comprehensive and optimal strategy for energy transfer within the area. It was effective when information on discounts and point systems in stores and shopping malls during specific time periods was provided. Results The peak cut effect in households: 1 kwh/household No difference in energy demand in commercial facilities. ていたん & ブラックていたん Office Building Line JR Space World Station Large Commercial Facilities Line Hydrogen ST Line Office Factory Complex Line Medium sized Commercial Facilities Line Public Community Line Condominium Line JR Yahata Station Load flow control for power interchange The power interchange in the area was possible by improving (i) unstable systems and (ii) power generation control required due to the mass introduction of solar power generation through (i) the introduction of community installed storage batteries and voltage regulators and (ii) absorption by consumers storage cells and heat/hydrogen converters through local collaboration. Results Coordination through CBP Information management through EMS It was demonstrated that a consumer s structureoriented mechanism for storing excess energy on the request of CEMS would be extremely effective. Households: CBP notification Thermal storage by a heat pump hot water supply system EMS: Energy storage by storage batteries, heat, hydrogen Available at sudden onset 17

Figures in ( ) indicate the percentage of consumers with the highest effect About 10% energy savings was achieved by adding the effects of mobility, hydrogen conversion and storage, and direct connections of solar power to systems. In addition, software that can derive energy management conditions from the knowledge acquired was also developed at the same time. The keys for local energy management worked together with consumers are as follows: To know the consumers structure and pursue solutions together and to find opportunities for collaboration with other consumers based on the data visualized by ICT. 19
