wave energy has been slow, by comparison, but, being less intermittent, it could play a valuable role in providing load balancing capability

Only if and once it is brought up to GW scale, which I doubt will happen on the short term. Linking with Britain will add some balancing, though I suspect weather is strongly correlated in the two areas (cyclone-related peaks and will be spread out and lulls narrowed by only a few more hours).
