Forgive my ignorance but doesn't connecting to other grid allow them to buy energy when prices are low and still allow them to generate their own when the national grid prices are high? It would also allow them to sell excess no?

It does but it appears the market unit for a block of energy does not match well with what is actually needed. So you might need 1-2 hours worth of extra power to hit peak demand but you have to buy 6 and dump the 4.

Depends on the needs of the market and their own generating supply. Arbitrage opportunities would surely exist in the short run while long run pushes the price to a natural equilibrium.
