Nice try at plagiarizing the work of fossil fuel industry-funded groups, but all of your claims were already debunked here:
You should talk to the U.S. grid operators who have more than 10,000 MW of wind on their power systems, MISO and ERCOT. ERCOT's incremental reserve needs for wind account for an additional cost of about $0.50/MWh of wind, or about 6 cents on a typical monthly electric bill. In contrast, the typical cost of the contingency reserves for large fossil and nuclear power plants is about 40 times higher. MISO has also explained that the impact of 10,000 MW of wind on its need for regulation is "little to none."
