Transmission is the “road to market” for renewable
energy. Since most new utility-scale
wind and solar resources are located in rural areas, transmission is needed to
transport this clean, low-cost energy to the electric grid where consumers can
benefit from it. CGA is the 'go-to' subject matter expert working ‘behind the
light-switch’ advocating for renewables and ensuring there is adequate access to the MISO electric grid. We also work to ensure transmission capacity is available for renewables, and
transmission projects are completed.
CGA met with the Environmental Law & Policy
Center who is representing the Driftless Area Land Conservancy against the
Cardinal-Hickory Creek transmission line in Wisconsin to understand their
concerns about the line. Read more about our work to support this vital line.
36% increase in forecasted amount of renewable resource expansion in MTEP.
At MISO, our advocacy resulted in an increase in the forecasted amount of renewable resource expansion in MTEP from a maximum amount of 52.8 GW in MTEP 18 to a maximum amount of 72GW in MTEP19.
worked to transition the MISO Interconnection Process Task Force (IPTF)
into the Interconnection Process Work Group (IPWG). After 10 years as a task
force, the IPWG provides a more permanent group at MISO to address ongoing
important issues for generation developers.
BY THE NUMBERS
CGA Staff gave a presentation to 45 OMS commissioners and staff on the interconnection and cost allocation challenges and the need for more transmission. We encouraged the group to make these issues a priority and work with us to support the study of additional transmission.
CGA submitted multiple comments to MISO,
advocated in stakeholder meetings, and made one formal presentation to support
MISO’s plan to file cost allocation changes that should increase the
possibility of approval of regional cost sharing of economically beneficial
transmission upgrades. These proposed
changes will lower the voltage threshold for cost sharing, and increase the
benefits included in the evaluation of projects. We were also successful in keeping MISO from
eliminating the Multi-Value Project (MVP) cost allocation category which was so
successful in supporting 17 regionally beneficial projects that were approved
CGA led technical advocacy efforts on MISO
Generator Replacement policy to ensure fossil fuels do not have an advantage in
the MISO marketplace when utilities retire coal plants and that the final
Generator Replacement policy is consistent with existing Generator
Interconnection and Material Modification policies.
continued to advocate for a forum at MISO to discuss and make progress on
Hybrid Interconnection policy. There is great interest in adding solar or
storage to existing generation sites but changes to business practices and the
MISO tariff will be required.
Following advocacy over a number of years and
support for this issue through MISO’s Market Roadmap Survey, MISO has included
an effort to develop Dynamic Line Ratings in its Market Roadmap Work plan for
2019. If implemented, Dynamic Line
Ratings can increase the amount of available capacity for use on the
transmission grid without building new transmission lines. This is especially important because it
allows for increased capacity during high wind periods given that wind speed is
directly related to capacity on the lines.
CGA worked hard in 2018 to ensure better
alignment between MISO’s annual Transmission Expansion Plan (MTEP) and
generator interconnection (DPP) policies and studies. MISO had originally
proposed to only allow RAS (Remedial Action Schemes), load shedding and
redispatch as options to mitigate constraints that were the responsibility of
Transmission Owners, but as a result of CGA's input, the same language was also
put in BPM 15, which applies to mitigating constraints in the Interconnection
Process. Previously, without this language, these options could not even be
