Most places need to expand the electricity grid so that electricity can be moved from where and when it is plentiful to places that can use it.
If you have a good east-west connection then energy can be sold into the time zones east and wet of the producer.
Good north-south connections mean that hot sunny locations nearer the equator can sell to consumers nearer the poles.
This is beginning to happen in Europe with the construction of big HVDC interconnects between Norway and the UK, Denmark, Germany and many smaller connections, but there is a still a lot of work to be done to connect Portugal, Spain, France, Germany, and countries further east and south.
