There have been a few studies that suggest a limit of about 20%. The reasoning goes that any greater penetration than that requires greater spinning reserve operating at poor efficiency so the net benefits of using a clean green variable source are negated.
Levesque does touch on the need for reserve but, as far as I could see, not the downside of its poor efficiency and the trade-off.
