It struck me the other day that metainfrastructure might exist. According to Google it exists in a computer engineer's vocabulary but it might exist closer to home.
TAN 8 describes the renewable energy infrastructure proposed by WAG but what about the infrastructure required to create the infrastructure? QED metainfrastructure. Roads are required to bring in large machinery but also, and in my mind more importantly, an electricity grid infrastructure to take the electricity out. TAN 8 cannot be delivered until a proper connection to the National Grid is established, there already exists a connection lag for renewable energy. There exists European legislation that prioritises the connection and transfer of renewable energy on the grid but it hasn't been adopted for the UK.
The scrutiny committees in the Assembly need to take a serious look at the infrastructure implications of TAN 8.
