COFFEE BREAK

Session 1 – Load Growth Forecasts and Flexibility for Planning
Session chair: Hannele Holttinen (recognis, Finland)

How do planners and operators forecast and plan for large new loads, and what flexibility can those loads actually be counted on to provide? This session examines forecasting practice, the resource-adequacy implications of concentrated load growth, and the difference between flexibility that is offered and flexibility that can be planned around.

Presentations:

• Forecasting for Large Loads Across the U.S.: Current Practices and Recommendations
  John D. Wilson (Grid Strategies, USA)
• Flexibility Framework: A Practical Approach to Operationalizing Load Flexibility
  Irene Danti Lopez (EPRI, France)
• Reflections and insights from Demand connections reform in GB (tbc)
  James Whiteford (NESO, United Kingdom)
• Emerald AI and the Disappearing Data Center: Time Clocks, Computation Flex, and Grid Rules
  Arushi Sharma Frank (Luminary Strategies, USA)

Discussion

LUNCH

Session 2 – Connection Processes and Network Upgrades
Session chair: Amy Rose (Energynautics, Germany)

Large loads are requesting connection to the grid faster than their impact on the grid can be assessed. This session looks at how system operators and utilities are managing connection queues and connection studies, and how they plan the network upgrades that new large loads require.

Presentations:

• Large Loads Connection Process and Studies​
  Vinay Sewdien (Krios Infrastructure, Netherlands)
• ERCOT’s Evolution in Large Load Transmission Planning, Flexibility, and Co-Location
  Jeff Billo (ERCOT, USA)
• Reflections and insights from Demand connections reform in GB
  James Whiteford (NESO, United Kingdom)
• Using BESS and Standardized Metrics to Support Large Load Connections
  Benjamin Braun (Fluence Energy, Germany)

Discussion

COFFEE BREAK

Session 3 Technical Reliability and Grid Codes
Session chair:  Alex Shattuck (ESIG, USA)

The rapid penetration of large loads significantly changes system performance during both normal and abnormal conditions as well as the assumptions necessary to perform studies that help ensure system stability in this new paradigm. The performance and modeling requirements needed to account for this paradigm shift are still being developed worldwide. This session covers the reliability impacts of large loads and the regulatory efforts to ensure large load performance, and modeling requirements emerging in the US and Europe can reliably integrate them.

Presentations:

• Large Load Performance Requirements in North America
  Julia Matevosyan (ESIG, USA)
• Requirements for large demand facilities in Finland – What is needed and why?
  Lasse Linnamaa (Fingrid, Finland)
• Performance Requirements for Large Loads in Ireland
  Taulant Kerci (EirGrid, Ireland)
• Balancing Grid Code Evolution with Large Load Operational Considerations
  Liam Morrissey (Google, Ireland)
• Data Centres Load Behaviour with the Upcoming Connection Requirements
  Önder Polat (WSP UK, United Kingdom)
