Full Changelog: v1.2...v1.2.1

Release v1.2

Enhancements:

In this release there were updates to ORBIT's cost model. Users can expect to see different CapEx results because of:

• Soft CapEx Methodology consistent with https://www.nrel.gov/docs/fy16osti/66579.pdf. Users can still specify a $/kW for all any CapEx categories.
• Common Cost (defaults) now employs a similar approach to NYSERD to adjust ORBIT's common costs (a.k.a default values) based on publicly available commodity indices. We updated all the common costs (design costs, cable, vessel day rates, project parameters, soft cost) to be updated as of 2024 dollars. See #187.

Improvements:

Some infrastructure needed a few fixes.

• The WISDEM API that connects ORBIT to WISDEM was out of sync and had some variable naming errors. See #183.
• Updated ParametricManager to be compatible with latest version of python-benedict See #189. User's should rebuild their environment.

Bug Fixes:

There was a units error in the characteristic impedance calculation that effected the power factor and ultimately determined how much power an HVAC cable can support. Note that HVDC cables were unaffected by this bug. With this fix, the AC power that each cable can handle is lower which means fewer turbines can be connected on the same array cable. See #186 for more detail on the issue and #188 for the PR.

New Feature:

• Added a new 220kV HVAC cable that can carry 400MW per industry feedback. cable file name: XLPE_1200mm_220kV.yaml
• Updated Project Manager documentation .
• A new common cost page to outline common cost approach.
