A mix of sources (e.g. a few solar and wind plants in different locations) overcomes much of the intermittency and storage issues. It usually requires upgrades to the grid and beyond that just some careful management of the (less regular) intermittency issues (whether storage or alternative sources on demand).
One plant should not be judged on its intermittency alone. Its just not how the system works at a connected-grid scale.
