1. NECESSARY DOCUMENTS – HAVE THESE ON HAND WHEN YOU’RE READY!

2. HOW CLEARWAY SENDS YOUR REQUEST FOR INFORMATION

VENDOR ONBOARDING IN THE COUPA SUPPLIER PORTAL (CSP)

Compliant W‐9 (form 2018 or later). Information provided on W‐9 must exactly match what has been registered with the IRS. Document must be fully filled out and signed. Certificate of Insurance COIs should be issued to Clearway Energy Group LLC / 100 California St, Ste 400 / San Francisco, CA / 94111

COI requirements are determined by type of business: Goods, Off‐Site Services, On‐Site Services, On‐Site Delivery, or Technical Advisory Services.

Safety Questionnaire and Documentation (ONSITE vendors only). Clearway’s onsite suppliers must be safety qualified. There is a copy of the questionnaire at the end of this guide so that you can gather your answers before entering the profile. These other documents are also requested where they apply:

EMR Documentation, OSHA Forms, EHS Certifications, Safety Program Table of Contents, Confined Space Entry, Equipment Lockout and Tagout (LOTO), Hazard Communication Program, Respiratory Protection Program

COUPA on the CUSTOMER SIDE: Clearway is only allowed to have one (1) primary point of contact on a Supplier’s profile in Coupa. This is what your profile looks like to us:

WHAT THAT MEANS FOR THE CSP: The primary contact field in our supplier profile is tricky in how it interacts with the CSP, best explained in if‐and‐then statements. If you need to unlink, email vendormanagement@clearwayenergy.com ‐ IF you are listed on our profile as the primary contact, AND your company has never linked with Clearway in the CSP, THEN

you (our primary contact) will always receive our requests for information ‐ IF you are listed on our profile as the primary contact, AND you elect to link with us in the CSP, THEN you (linked party) will

always receive our requests for information ‐ IF you are added to our supplier profile as the primary contact internally by Clearway, AND that happens AFTER another

user has already linked with us in the CSP, THEN that other party (the person to whom we are still linked) will continue to receive our requests for information (often times, a company will have a single CSP administrator who is not necessarily the primary contact for the business)

‐ IF you are listed on our profile as the primary contact and you elect to link with us in the CSP yourself, AND you update your primary contact on the profile yourself, THEN you (linked party) will continue to receive our requests for information

3. THE COUPA SUPPLIER PORTAL

THE FORM LOOKS THE SAME!: The last section will show you what the form looks like in your portal; here’s what it looks like in ours (it’s the same!):

THE EMAIL INVITE: if you have never linked with Clearway before, you will receive an initial email with an invitation to connect to the portal with this language:

Congratulations! Clearway Energy has added you as a supplier on the Coupa Supplier Portal. Click below to sign in so you can Configure your PO transmission preferences, Create an online catalog, View purchase orders, Create electronic invoices.

If we have gone ahead and sent you a request for information rather than an invitation to link, the email will look like this:

RESPOND WITHOUT JOINING: You have the ability to respond to requests for information without joining the CSP – the version of the form is the same and provides us with the same information. We would just need to send you a form any time you want to update information.

JOIN AND RESPOND (Recommended): A supplier has a single profile in the CSP that is available for you to use with any of your customers who use Coupa (one to many – many of your customers can link to your single profile), allowing you to manage your information with any of your customers who use the platform from a single login. Choosing to join also allows you to make updates to your information with Clearway without us sending you a request to update your information – you can make updates to your profile, submit them to us, and we will review and apply. Joining the CSP also gives you access to your Clearway POs and the ability to invoice directly against them. We do recommend our suppliers choose the Join and Respond option.

THE INTRO SCREENS ARE TRICKY!: If you DO join the portal, the initial screens are a little tricky! They’re going to lead you through setting up your basic information and then they will tell you that you are ready to do business with Clearway – and that’s true from the standpoint that you will now be able to see your Clearway POs and invoices in the CSP. However, it unfortunately does not mean you have submitted your supplier information for us to review as far as your supplier profile with Clearway goes, that’s part of the Clearway customer profile within the CSP. That’s the next section of this guide, but these are the intro screens:

MANAGING YOUR CSP: We recommend setting up remit‐tos and adding any other users who might need to make updates to the Clearway profile to the CSP before making your profile updates. That is done under the Admin section of your Setup tab:

When adding remit‐tos, you’ll be able to populate the banking info and you’ll want to make sure you give Clearway access to the remit‐ to you want to use with us:

MERGE REQUESTS: If multiple users in your company have set up logins to the CSP, Coupa will first recognize by email address and ask you if you’d like to merge these accounts into one (as the intent of the CSP is to have the one‐to‐many relationship, all internal users of the same supplier interacting with their customers through the same CSP – the CSP allows for multiple legal entities of your company to be setup in the Admin for this purpose as needed).

4. THE CLEARWAY PROFILE WITHIN THE COUPA SUPPLIER PORTAL

You can also request a merge via Setup‐>Admin‐>Merge Requests, though we have heard from some suppliers that this is not always successful. We recommend reaching out to Coupa Support via their Chat function if the attempt to merge under Admin is not successful.

The Chat with Coupa Support option is always on the bottom right corner of any page of the CSP:

PUBLIC PROFILE vs CUSTOMER PROFILES – Information that is entered in the CSP but not in the Clearway profile is not transmitted to Clearway, this is the difference between your public profile and your customer profiles – your basic business info is the public profile, and you manage what information in the CSP you want to use with each customer by filling out their customer profiles. Both profiles are found under the Profile tab in CSP:

THE CLEARWAY CUSTOMER PROFILE – Finally, we’re here! This is where you will transmit supplier information to Clearway for vendor qualification, remit‐to updates, etc. This is the link to us! Under the Profile tab, you will select Your Customer Profiles and then Clearway Energy in the Profiles dropdown:

There are nine (9) sections to the Clearway profile: − HEADER: Legal entity name, DBA, the scope of work you perform for Clearway, the supplier type you are to Clearway, and DUNS

if applicable. Please be descriptive and clear when filling out the scope of work information as we use this to evaluate insurance requirements. Please also make sure that the way you enter your legal entity name and DBA name on your profile exactly matches what is on your W‐9.

+

7

− TAX INFORMATION: Here’s where you’ll need your W‐9. Please note that we require a new vendor setup if you have a new TIN rather than a profile update (clicking the box asking if a new Tax ID is provided indicates to our VM team that a new vendor needs to be set up rather than the current vendor updated) – we recommend you reach out to our VM team at vendormanagement@clearwayenergy.com if you have received a form for update/linked with Clearway under a supplier profile that requires a new TIN.

− ORDERING DETAILS: This is where you would indicate your ordering address and the correct email address for receiving purchase

orders from Clearway.

+

8

− CONTACT DETAILS: This is where you will manage your primary contact with Clearway. Note that this person will receive any requests we send for information.

− REMITTANCE DETAILS: This is where you will manage your remit‐to information with Clearway – both the email address you want notified when payment is made and the account info to which you would like us to make payment. When you are linked to us in the portal, you can update your remit‐to with Clearway at any time by entering the profile, updating this section, and submitting the new profile information to us to review and apply. If you have already set up your remit‐to in Setup‐>Admin‐ >Remit‐To, you will be able to select it when you click the Add Remit‐To button; otherwise, you will be asked to input your desired payment address and payment method.

− INSURANCE: Here’s where you’ll need your COI! All suppliers to Clearway are required to hold insurance and provide Clearway

with a certificate of insurance held. A sample COI is included with this guide which lists our insurance requirements. Please note: suppliers who do not meet these requirements are not automatically disqualified; they are additionally reviewed by Clearway Risk in the qualification process – this is why we ask for clear and descriptive information in the scope of work section.

+

9

− SUPPLIER DIVERSITY: Clearway is dedicated to equity in business and asks for minority and small business information from

suppliers who identify in this manner.

− ENVIRONMENTAL: Clearway’s mission is to make and provide clean, competitive, and reliable energy while doing good by our

customers, our communities, our environment, and our people. As part of our dedication to doing good by our environment, we ask for our suppliers’ sustainability information for those who participate in such efforts.

+

10

− SAFETY: Here’s where the safety questionnaire comes into play! This is only required of onsite suppliers. If you have already

gathered your answers to the questionnaire and other safety documents based on the copy attached and the instructions on top, you should be able to breeze through this part pretty quickly.

+

11

AND THAT’S IT!... You’ll be ready to submit your profile to Clearway for review, approval, and application to your supplier profile. Note – there is also a Save button: for suppliers who will have multiple people working in the profile before submitting it for our review, you’ll want to make sure you Save between each edit to ensure the information is captured.
