MODERATE

The bill was significantly rewritten from an original version to a committee substitute version. The original bill focused only on adding a new section for integrated resource planning, while the committee version repeals an existing section (393.135) and replaces it with three new sections that cover construction work in progress, capacity planning, and integrated resource planning. This expands the bill's scope from just planning requirements to include financial regulations and capacity obligations for electrical corporations.
