My knowledge is not really on date but as far as i know we still have no battery system good enough for long term electricity storing and what we are using right now are used for short term energy peaks, not storing the energy in summer so we could use it on the winter.
Yes we have HVDC, but it has its problems when electricity is coming from multiple smaller plants, especially when there production and demand is not even. Basically i mean that if there is side of a country that is not producing anything and if there is a other side that is overproducing, the current system we have, is not able to smooth that out. Granted it is a problem that could be solved with tossing money and engineers at it.
