    1 INTRODUCTION

    London Power Associates Ltd has been asked to carry out an external peer review of the following documents:

    Grid 25 review (2015) Main report

    Grid 25 review (2015) Technical report

    1.1 Background Grid25 Strategy (2008): The publication of Grid25 was a major initiative in 2008, in taking a long-term strategic view of transmission infrastructure investment. The aim of the strategy was to avoid a less efficient incre-mental approach to grid development, thereby minimising unnecessary expenditure whilst ensuring compatibility with wider national and European policies and directives. Grid25 provides a Strategic Overview for anticipated grid development up to 2025 and beyond, based on a strategic Vision, identifying strategic Future Grid Requirements and, in this context, setting out a Grid Develop-ment Strategy. The Vision of Grid25 was to deliver a strong cost-effective transmission grid, which is essential for Ireland to facilitate regional economic growth by attracting high-tech industrial in-vestment. Grid25 intends to deliver high quality, secure and competitive electricity supplies to cus-tomers and, by connecting new renewable and sustainable energy sources, reduce Irelands over de-pendence on fossil fuels. Grid25 will also support further interconnections to the UK and mainland Europe, which improves security of supply and encourages competitive energy prices in the All Is-land Single Electricity Market.

    1.2 Purpose of 2015 Grid25 Review: EirGrid drafted a Grid25 review which assessed changes since 2008 and the impact of those changes on the strategies and on the major projects progressing as part of the strategy implementation.

    The Technical Report provides more detail on the Technical Issues.

    The main topics covered are:-

    Progress since 2008 The Evolving Context Drivers of Grid Investment Technology Revised Strategies Regional Development and Major Grid Development Projects

    Following a tendering process EirGrid invited London Power Associates to fulfil the role of Inde-pendent Peer Reviewer and to carry out an assessment of the Grid25 review (2015) documents (Main report and Technical report).

    The main tasks included: Part 1: Review the Grid Development Strategies

    Consideration was given to:
