Reliability costs associated with backstopping renewables could rise to $435 billion a year around the world by 2030, the company said in a report released Wednesday.As utilities increase the amount of renewable energy in their fuel supply mixes, the associated need for an increase in resource buffers could lead to oversupply that would increase power price volatility and grid reliability costs, said Moody’s Investors Service in a Wednesday report.
“Because wind and solar power generation depends on weather conditions and is thus not dispatchable, load-serving utilities will likely build in a cushion of supply to enhance reliability and compensate for resource volatility,” the report says.

The Energy Department launched a competition Monday for long-duration energy storage, offering $349 million for successful demonstrations of a technology widely seen as crucial to a carbon-free grid.
Utility Dive: Upheaval in utility regulation emerging nationally as Hawaii proves a performance-based approach
Utility Dive compared reforms for utility performance, quoting AEE's Ryan Katofsky on how Hawaii's low-cost reforms are improving service. Read snippets below and the full article here.
Many states are working on regulatory reforms focused on utility performance, but some compromise approaches may be self-defeating, performance-based regulation, or PBR, consultants said.
