ESBN/EPRI EV Project Objectives

Assess capacity of LV Network for EV

Assess potential barriers to future Vehicle to Grid

Assess possibility of using EV as ballast load for WIND,

Assess feasibility of faster charging on LV network by using Smart Meters to share charging capacity

Progress to date• Wind

– Follow up Use Case progressed further– 38kV Voltage Regulator currently being installed for Project 1– 1 Month 5sec Metering data collected for two Wind farms for Project 2– Single Transformer Station Design almost completed

• EV Project– Initial Use case progressed– Contract for EV’s purchase completed to arrive in Summer

• Green Smart Circuits– One Circuit provided to EPRI for initial Modelling– Amorphous Core Transformers Sourced– Lab testing of Micro-Planet completed

EU and Irish Government Policy for Smart Meters

Implementation of EU directives

Program for Government proposes smart meters

Energy Regulator governed Phase 1 –National Smart Metering Plan (pilots and cost benefit analysis)

Significant gap between DNO costs and benefits

Regulator Needs to be assured smart meters can deliver demand management, overall consumption reduction and support of renewables.

National Smart Meter Customer Behaviour TrialObjective is ‘to ascertain the potential for smart metertechnology to effect measurable change in consumerbehaviour’

Q4 2008-Recruitment

6400 statistically representative customersOne year profile data per customer (at least 6 actual months) for benchmark period

One year of stimuli and new time of use tariffs

Final conclusions by CER based on ESRI National Business Case Study

Technical challenge to deliver daily validated ToU data to be used for real billing
