Onshore Wind
There are huge onshore wind potentials in north part of Japan, Hokkaido, but electricity demands are done in Tokyo. There is very weak grid connection between Hokkaido and Japan main land and the capacity of grid connection is mere 60GW. Grid expansion make possible to access to Hokkaido on-shore wind potential.
In addition, storage also plays a role to boost onshore wind. Onshore is intermittent generation technology and storage will charge excess generation from onshore wind and discharge when generated electricity is less than demand.

Elasticity is the biggest in storage scenario and storage will work as back-up battery for solar to match between demand and supply. The potential of solar are geologically equally distributed in Japan and geological un-matching between potential and electricity demands are not big.

Same as onshore-wind, offshore-wind benefits from both storage and grid expansion. However, elasticity in storage scenario, 7.57, is more than that in grid expansion scenario, 3.95, because offshore wind potential is geologically equally distributed all over Japan.

V. Lessons
Conventional top-down model fails to represent substantially different technological futures.
Common deficiency of tech-bundle CGE is the lack of the real estimates for the model parameters.
Using parameter estimated by detailed bottom-up which is complex enough make top-down model reflect technology completeness.
