November 213 Introduction Table of Contents Page # ACS Buildings & Grounds 2 Purpose and Scope ACS Buildings & Seismic 3 The purpose of these ( Plans ) is to demonstrate how we intend to deliver on the strategies set out in ACS Capacitors & Reactors 4 the related Fleet Strategies. The Plans provides detailed schedules for planned expenditure in our Grid asset portfolios. ACS Disconnectors & Earth Switches 5 ACS Dynamic Reactive Power 6 While detailed planning for some of the near term works has already begun, the Plans should be considered dynamic and subject to ACS Indoor Switchgear 7 regular updates and reviews. Updates will occur for a number of reasons, including: ACS Instrument Transformers 8 ACS Other Station Equipment 9 1. potential for project substitution across Base Capex ACS Outdoor Circuit Breakers 1 2. addressing newly identified risks and changes to the Grid ACS Outdoor to Indoor Conversions 11 3. revised prioritisation through ongoing Integrated Works Planning (IWP) processes ACS Power Cables 12 ACS Power Transformers 14 Expenditure Forecasts ACS Structures & Buswork 15 Consistent with our Fleet Strategies the main types of expenditure described in these Plans are: HVDC 16 SA Batteries & DC Systems 17 1.
