With EU regulations demanding European countries contribute to the cost of new infrastructure, the time to invest is now
In Europe, electricity is a commodity traded on an hourly or half-hourly basis, often months ahead of its actual use in homes or businesses. Every unit of electricity that we consume is traded several times before it is delivered.
There is a single electricity market in Europe (the biggest in the world), but not a single price for electricity. There are still barriers to trade, some to do with regulation and others created by missing physical infrastructure.
