A new ScottMadden report describes the challenges of balancing renewables and natural gas with retiring baseload power plants.

Utilities need to prepare for the rise of wind and solar power and the retirements of baseload power plants, and that includes building “solar protection factors” into their long-term planning.

That’s one of the recommendations from consultancy ScottMadden in its latest energy industry update. The report, which covers subjects ranging from Trump administration energy policies, to blockchain, to smart cities, also gets into detail on today's key grid paradigm shift -- the increasingly frequent retirements of coal and nuclear power plants and their replacement by natural gas and renewables.

In the past decade, for the first time ever, baseload retirements outpaced baseload additions, with 23 gigawatts of net retirements since 2010, the report found. Of the 84.2 gigawatts of retirements, 61 percent were coal and 29 percent gas steam turbine plants, while the 61.1 gigawatts of additions have been 74 percent combined-cycle natural gas and 24 percent coal steam turbines.
