We continue to work with governments and regulators on the reform necessary to create a clear and stable investment framework. Our capital expenditure was £3.3 billion during 2009/10 as we made essential investment to meet our customers’ needs and begin to enable connection of changing sources of energy.
We are also driving improvements in the reliability of our transmission system and, in 2009, a major phase of investment in New England involving seven integrated transmission line and substation projects came into service. The new gas insulated switchgear substation at Wakefield Junction was designed to meet the long-term energy delivery needs of the greater Boston area and also, through removing obsolete sulphur hexafluoride (SF6) equipment, plays an important role in reducing our own greenhouse gas emissions.
