Without visual insight into a power network, it is very difficult to identify a problem, let alone solve it. A good graphing tool is therefore very important to help one understand a power network, identify any issues and come up with the solutions.
Leo Smith of Gridwatch has done a cracking job of making electricity data available on an online resource. The data available through his website includes total demand, total generation from different generation types, interconnector flows and frequency with a temporal resolution of approximately 5 minutes.
There are four electricity interconnectors linking Great Britain (GB) to Ireland and continental Europe with a transmission capacity of 4 GW. These links represents approximately 5% of the GB’s electricity generation capacity.
