Creation Project(Energy Field)
Consumers, such as local residents and businesses, will modify theirbehaviors to become “pro-sumers,” not simply energy consumers,
through the installation of solar power and independent energy saving
Cluster Energy Management System (CEMS) and smart meters aremechanisms for discovering, sharing, and utilizing regional energy,
including hydrogen by-products and steam in neighboring factorycomplexes, as well as solar and wind power.
Actions that act in the own interests of the residents and businesses willbuild a mechanism that also simultaneously contributes to the local energy
system by introducing “concentrated and visible” energy information for thearea and dynamic pricing.

Residents and businesses alike create new energy systemthat incorporates “ideas and participation.”

Basic Approach to Dynamic Pricing【Basic Approach】
Fluctuates power rates daily, predicts time periods in which demand may exceed supply, and promotes energy saving actions
by power consumers in response to changes in supply and demand due to weather and temperature.

① Power/energy savings
Peak cuts② Optimal use ofrenewable energy andpower③ Town management(Sustainable model)

Social model for excesses in power supply
and demand① Basic pricing (Higashida pricing by season/time)→ Leveling the system power base② Real time pricing→ Fine power load leveling (actual/predicteddemand) and power oriented operations③ Critical pricing→ Control of demand on specific days

Social model for introducing large amountsof renewable energy① Power rates based on introduction of (prospects for) renewable energy② Power rates based on use of renewable energy/storage batteries

Independent local conservation powerstation model① Town management② Examination of business modelsEffects of Dynamic Pricing
・June-Sept 2012: Implemented 40 days, 180 samples
・Fluctuate prices in four stages between 13:00 and 17:00 on weekdays for days whentemperatures exceeded 30℃ and verification of effects of power savings in pricing.
Effects of dynamic pricing only
Level 1¥15/kwhBase price

Level ２¥50/kwh—9.0%

Level ３¥75/kwh—9.6%

Level ４ ¥100/kwh—12.6%

Level ５ ¥150/kwh—13.1%【Reference】
Revised effects of dynamic pricing with the addition of seasonal and time
specific pricing (TOU)—18.1%
Level ２¥50/kwh¥75/kwh—18.7%

Level ４ ¥100/kwh—21.7%

Level ５ ¥150/kwh—22.2%

Level ３・ Peak cuts from effects of dynamic pricing exceeded maximum of 10%.
・ Peak cuts from added TOU effects exceeded maximum of 20%.
・ The higher the price, the larger the effect of peak cuts.
