Its really a catch-22 type thing. You increase renewables, destroying the viability of base load. That forces more short term power producers into the market, that then inefficiently burn gas to produce when renewables are off. The gas plants are profitable because the prices you have to pay them are pretty high. And this problem is getting worse all the time and its not really a great overall strategy. I would argue renewables are subsides by how they use the grid. In the US renewables even get subsidies for energy they produce and sell at negative prices.
