In the fall of 2017, Catalyst Cooperative was engaged by climate advocates to perform a rapid review of the Platte River Power Authority’s [Zero Net Carbon Portfolio Analysis](https://www.prpa.org/znc/znc-report/). The PRPA ZNC report was released to the public on December 7th, and we delivered [our final report](/content/files/2017/12/Catalyst-Cooperative-Review-of-PRPA-ZNC-Portfolio-Analysis-2017-12-18.pdf) on December 18th.
