4.1    Introduction

Recent catastrophic blackouts in New York, London, and Italy (August and September 2003) have exposed major vulnerabilities in existing generation, transmission, and distribution systems. Severe underinvestment, aging technology, and conservatism in the approach to innovation are being blamed and have created a situation where reliability of the entire system is under question. Resources need to be directed into technologies that have the potential to improve ...
