Regional Energy Deployment System (ReEDS)
• LP: Minimize power sector’s costs of
operation and investment
• Detailed characterization of
renewable capacity
• High spatial*, technological, and
temporal* resolution
• Used in > 100 publications

SLiDE
• Scalable
– Geographical: Counties* -> Nations
– Sectoral: Broad -> Specific
• Linked
– With sector-specific planning and
operations models
• Dynamic
– Consideration of future market conditions
– Myopic -> Intertemporal representations
• Equilibrium
– Linked version in GAMS
– Open-source model written in

Appendix
• Minimum return on investment constraint (require price as variable or
markup?)
• Integer decisions on…
– Plant investment
– Product pipeline, storage, and injection (?) investment (primarily CO2,
H2)
• Notes on regional scaling:
– Downscaling state-level demands
– County-level for corn/stover/woody
– Downscaled from state on FOG/MSW
– Mappings to CENDIV/state/…
