DOE GRID MODERNIZATION INITIATIVE
OtherGov’t
An aggressive five-year grid modernization strategy for the Department of Energy that includes
• Alignment of the existing base
activities among DOE offices
• An integrated Multi-Year
Program Plan (MYPP)
• New activities to fill major gaps
in existing base
• Development of a laboratory
consortium with core scientific
abilities and regional outreach

► Distributed, hierarchical control for clean energy and new customer-level services
Target Partners:
► Distribution utilities
► Cities and municipalities with ambitious clean energy goals
Goals:
► Use coupled T&D grid
planning models with 1000x
speed-up to address specific
grid-related issues
► Work with States to evaluate
new business models,
impacts of policy decisions
Target Partners:
► States and local regulators
► Distribution utilities
► New market participants
Lean Reserve Bulk Power Systems
Clean Distribution Systems
Grid Planning and Analytics
Three types of public-private partnerships that will accelerate transition of Foundational R&D outcomes to widespread deployment at scale

• Flexibility will be important for the modernized grid
• Storage is a key option for providing flexibility, BUT
o Must realize multiple values to be economic today
o VERY use case specific
• Continued innovation needed for storage to co-exist with other flexibility options
o At very high RE levels, all options will be needed
KEY TAKEAWAYS
