How are wind integration costs spread over large market footprints and regions? • Wind Integration Costs
– Costs of transmission infrastructure necessary to interconnect the wind generation to the BES
– Costs of delivering wind generation across the footprint • Infrastructure investment • Operational costs
• Interconnection costs – Local interconnection upgrades paid for largely by generator; 10% of 345 kV and
above upgrades postage stamped across footprint • Delivery costs – infrastructure investment
– MISO has multi-value project portfolio that was primarily driven by the Renewable Portfolio Standards mandated within the MISO states – 17 EHV transmission projects
– Costs are postage stamped across the footprint
15
Are Operating Reserves additions needed • MISO’s geographic diversity, large Balancing Area,
and Dispatchable Intermittent Resource Product have allowed MISO to not increase Operating Reserves to date
16
How do operators ensure reliability in a low load situation
• MISO uses advance notice of potential Minimum Generation situations to allow generators to choose to do maintenance
• When in a Minimum Generation situation: – MISO can use Dispatchable Intermittent Resources to dispatch
down – MISO can use emergency ranges of generation
