Curtailment Index 8

Agenda Flexible connections Curtailment overview Benefits Annual customer Example – HV connection Curtailment figures information Questions & Close

Flexible connections Managed connection Post fault demand Triggered at time of Remote terminal unit Uses 3G technology response system fault and (RTU) is installed at to communicate with Offered to all new planned outage (ie time of connection Electricity North DG connections When system normal maintenance and West >200kW at HV and = ON construction) EHV When system Offered to new I&C abnormal = OFF connections where a flexible connection has requested

Curtailment overview Curtailment Actual Customers Forecast index curtailment Forecast based on historical data & planned work Considers fault, construction & Customers are provided Curtailment Index contained maintenance outages If customer approaches or annually with actual within new flexible Provides indication per exceeds cap ENWL will seek curtailment figures for connection offers from 4th voltage type of forecast to intervene previous 12 months, and December 2017 who have curtailment cumulative six-year average maximum import capacity / Figure is provided as a % and maximum export capacity Provided to customer with no. of days for a rolling six- Provided through collation of >200kW connection quotation year period network data

Curtailment figures 6.6 & 11kV (HV) 33kV (EHV) 132kV (EHV) Faults 5 days 15 days 15 days Maintenance 0.2 days 1.5 days 13.5 days Construction 4 days 8.3 days 12.5 days Forecast 9.2 days (2.5%) 24.8 days (6.8%) 41 days (11%) (based on historical data) Curtailment Index 11.4 days (3.0%) 29.8 days (8.2%) 49.2 days (13.2%) (intervention trigger)

Benefits • Customer provided with a clear expectation of average interruption to their operations • Allows network outages to be modelled realistically to aid customers investment decisions • Curtailment Index provides safe guards against excessive outages or faults • Clear performance expectation • It provides an equitable basis for Active Network Management • Enables introduction of ‘Service Metric and associated investment’ in RIIO ED2 • Exceeds commitments set out within our ICE plan

Annual customer information At the end of the first full financial year following energisation or commissioning of the RTU, customers will receive a letter providing them with the previous 12 months outage data (April to March), for example: The letter will also indicate whether or not intervention is required due to the figures shown.
