Energy Delivered to Platte River’s Four Municipalities in 2014–Proportions by Source:
- Coal 74.2%
- Hydropower 19.1%

Certificates (RECs): Renewable energy certificates represent the title
to environmental benefits associated with energy produced from a renewable
energy generation facility and are sold separately from the electricity commodity.
RECs are combined with energy produced by Platte River’s other resources
to form a more affordable renewable energy product (see Renewable Energy in Glossary).
