Submission CEDE Solar and Wind - renewables support

I talked to Matt Jones today.

Onshore and Offshore wind farms. Missing Construction CEDE Codes for wind farms

240 | Offshore Wind Turbines | Offshore wind turbines are installed individually and in groups called "wind farms". Wind turbine systems comprise a tower, hub and blades (the rotor), and nacelle (houses the generator). They are typically attached to a reinforced concrete foundation. Based on the wind characteristics of the site, these structures are generally designed to conform to the International Electrotechnical Commission (IEC) 61400-1 wind turbine design class.

239 | Onshore Wind Turbines | Onshore wind turbines are installed individually, and in groups called "wind farms.". Wind turbine systems comprise a tower, hub and blades (the rotor), and nacelle (houses the generator). They are typically attached to a reinforced concrete foundation. Based on the wind characteristics of the site, these structures are generally designed to conform to the International Electrotechnical Commission (IEC) 61400-1 wind turbine design class.

Solar exposure support We will submit the new exposure support (8 constructions, 6 occupancies) before mid November.

Many thanks

@benhayes21 related to this, could you please: modify the description in PowerCapacity Loc Input field from '(e.g. in MW)' to '(in MW)' as it needs a definitive unit.

In terms of Offshore Wind Turbine there is an existing OED Construction code 7016 - the CEDE code column needs updating to reflect the above and please update the description as there is a typo: 'Key Loc fields to define the turbine are: Capacity and FoundationType.' should be 'Key Loc fields to define the turbine are: PowerCapacity and FoundationType.

Hi Matt,

Here I am sharing Verisk proposal for new con-occ codes for Solar installations for review.
Please let me know if you have any questions.

@ibehnert thanks for this. Some suggestions and queries..

• you currently have occupancy code 3050 listed for all 6 occupancy options. Suggest 3050 is preserved for 'general onshore solar energy' and 3051 - 3056 is used for those you have listed.
• In respect of construction values these would need to increment - 7 of those suggested are 7050
• The suggestion of BESS construction type 7054 is consistent between your suggestion and Renew Risk so this makes sense
• Note that the axis of ground mounting is already covered via a suggested new field by Renew Risk - 'PVMounting' and this covers the 4 options you give here. We shouldn't include this both ways.
• We already have an 'anchorage' field in OED 'Anchorage for energy, water and communication infrastructure'. So an alternative is instead of different construction values for anchorage we could add 'rooftop ballasted' as an extra value to this instead (unknown and anchored are already options).

This may require tying up a bit better with what Renew Risk are proposing, but this is an updated version.

It looks good to me. I agree with this proposal.
Thank you

Hello Sambles,

I am not familiar with the language on GitHub. Could you please confirm that CEDE solar con-occ codes & the wind farms 2 construction codes are now part of OED. Thanks

Hi @ibehnert I see changes to ConstructionValues.csv from #261

These are included in v5.0.0

Does that line up with what you're expecting, or should this issue be reopened?

[ibehnert]

Hi there,

I could find the onshore construction only 239/ CEDE, nothing about CEDE offshore wind farms construction code: 240
Could we have a call to understand where the solar risk codes are in this table. We shared them in Nov.

I am available on Thursday morning between 9am to 12pm, My email address is ibehnert@verisk.com
Could you please send an invite.

Thanks
Irina
