Build, Repeat. (A Paces Podcast) Why grid planning is the hardest problem in energy right now with Derek Stenclik
Feb 17, 2026
Derek Stenclik, founding partner at Telos Energy and former GE grid planning engineer, discusses grid planning challenges. He covers scenario-driven modeling, explosive load growth from data centers, and the rise of load flexibility and batteries. They also touch on interconnection queues, siting and permitting mismatches, and affordability and cost allocation risks.

Episode notes
Grid Modeling Is The Foundational Tool
- Telos focuses narrowly on grid modeling across timescales from sub-second dynamics to hourly resource adequacy.
- Accurate simulation is foundational to planning transmission, generation, and operations for a changing resource mix.
Unexpected Large Loads Hitting Small Utilities
- James described a Midwestern utility with 1.6 GW peak suddenly facing multiple projects each ~80% of peak load.
- Derek confirmed similar explosive growth appears across utilities and ISOs, just at different scales.
Plan With Broad Scenario Sets
- Use wide scenario analysis to manage unprecedented forecast uncertainty instead of treating a single load forecast as gospel.
- Run many combinations to test how today's investments perform across plausible futures.
