 EXHIBIT 10.30 

Umbrella Agreement to Sell and Purchase Wind Turbines 

This umbrella agreement (“Umbrella Agreement”), effective June 30, 2015 (“Effective Date”),
memorializes that Gamesa Wind US, LLC (“Seller”) and Iberdrola Renewables, LLC (the “Owner”) agree for Seller to sell, and for Owner or its affiliates to purchase Wind Turbines in multiple transactions (each, a
“Transaction”) for projects (the “Projects”) substantially in accordance with the terms and conditions of this Umbrella Agreement, including the terms in Seller’s Proposal GWUS 15-047, dated June 19, 2015
(“Proposal”) attached hereto as Exhibit 1. Seller and Owner each may be referred to in this Umbrella Agreement individually as a “Party”, and collectively as the “Parties”. 

This Umbrella Agreement sets forth the basic terms of the proposed Transactions which shall be more fully reflected in definitive agreements
(the “Supply Agreements” as they are defined in paragraph 3 of this Umbrella Agreement) to be negotiated by the Parties. 

WHEREAS, Seller is engaged in the business of manufacturing and selling wind turbine generators, parts and components (the
“Wind Turbines”), and providing erection supervision, commissioning, and operation and maintenance services (the “Work”) for such Wind Turbines (together, the Wind Turbines and Work constitute the “Supply
Items”), and wishes to sell such Supply Items to Owner; 
 WHEREAS, Owner is engaged in the development and operation of
renewable energy projects, which include wind-powered electrical generation facilities, and wishes to purchase the Supply Items from Seller for the Projects; and 

WHEREAS, the Parties have entered into the Equipment Supply Agreement dated December 28, 2014 (as amended, the
“ESA”), and wish to modify the ESA to the extent related to the Projects as described in this Umbrella Agreement. 

NOW, THEREFORE, in consideration of the premises and for other good and valuable consideration, the receipt and sufficiency of
which are hereby acknowledged, the Parties agree as follows: 
  

	 	1.	Award of Supply for [***], [***] and [***] Projects. Pursuant to the terms and conditions set forth herein, Owner hereby grants to Seller the exclusive right to supply all Supply Items for [***], [***] and [***]
Projects, provided, however, that if Supply Agreements are executed for such Projects, the terms of such Supply Agreements shall control for each applicable Project. Up to and including the date of expiration or earlier termination of this Umbrella
Agreement, Owner shall not, directly or indirectly (through other companies controlled by, controlling or under common control with Owner), enter into negotiation or any kind of agreement or undertaking with any other party for the supply of Wind
Turbines to the Projects. 

  

	 	2.	 Notices to Proceed. Owner shall issue corresponding Notices to Proceed (“NTPs”) under Supply Agreements for [***], [***] and
[***] no later than [***]. If the Supply Agreements for [***],[***] or [***] are not yet in executable form by [***] then Owner shall nevertheless issue NTP for such Projects and, until the Supply Agreements for such Projects are executed, the
rights and obligations of the Parties with regarding Supply Items for each Project shall be governed by the terms and conditions set forth in the executed 



  
 *** Confidential treatment has been
requested for redacted portions of this exhibit. This copy omits the information subject to the confidentiality request. Omissions are designated as [***]. A complete version of this exhibit has been provided separately to the Securities and
Exchange Commission. 









	 	
[***] Delivery and Purchase Contract between Gamesa and [***] dated as of [***] )(as amended, the “TSA”) and Warranty, maintenance & Service Agreement between Gamesa and
[***] (as amended, “WMSA”), as modified by (i) the applicable NTP, (ii) this Umbrella Agreement, (iii) the Proposal attached hereto as Exhibit 1, and (iv) certain agreed changes made to provisions of TSA,
attached hereto as Exhibit 2 (collectively, the “Specified Proposal Terms”). Further, Parties agree that TSA and WMSA, including their exhibits, shall be Project specific. The Parties shall continue to use commercially reasonable efforts
to finalize and execute the Supply Agreements by [***]. 

  

	 	3.	Form of Supply Agreements. The Supply Agreements for each individual Project shall consist of (i) a Wind Turbine Delivery and Purchase Contract, and (ii) a Warranty, Maintenance, and Service Agreement
(together, the “Supply Agreements”). The Parties shall execute the Supply Agreements, for each Project, substantially in the form of the TSA and WMSA, except as such agreements may be modified by mutual agreement of the Parties.
Furthermore, the Parties agree that the executable Supply Agreements also shall be modified, as necessary, to incorporate the Specified Proposal Terms. 

  

	 	4.	Quantity. Owner agrees to purchase, and Seller agrees to sell, up to the Project-specific quantity of Supply Items indicated in the Project Overview (Page 2) of the Proposal. 


 

	 	5.	Reservation of Production Capacity; Exclusivity. Upon execution of this Umbrella Agreement, Seller shall reserve production capacity sufficient to supply the Supply Items to Owner in the quantities and on the
schedules contemplated in the Proposal. If Owner fails to issue NTP for any Project by the applicable date set forth in paragraphs 2 and 3, above, Seller shall be entitled to release such production capacity to other customers without any liability
or obligation to Owner, and the pricing indicated in the Proposal for such Project shall be void. As a consequence, if Owner then wishes to issue NTP for such Project at a later date, all pricing and Project schedules shall be subject to
renegotiation and Seller’s then-current production capacity. Furthermore, upon expiration or earlier termination of this Umbrella Agreement, Seller shall be entitled to release such production capacity to other customers without any liability
or obligation to Owner. 

  

	 	6.	[***] 

  

	 	7.	Announcements. Neither Party shall make any public announcement regarding the Transaction or this Umbrella Agreement without the express written consent of the other Party, which consent shall not unreasonably be
withheld. Press releases regarding the Transactions shall be mutually agreed upon by the Parties. 

  

	 	8.	 Confidentiality. Article 9 of the ESA is hereby incorporated by reference in and as part of this Umbrella Agreement. The Parties acknowledge
that the “legal process” exception in Section 9.3(iv) includes disclosures of confidential Information to the extent necessary to comply with each Party’s reporting obligations under applicable law and securities exchange rules.




  
 *** Confidential treatment has been
requested for redacted portions of this exhibit. This copy omits the information subject to the confidentiality request. Omissions are designated as [***]. A complete version of this exhibit has been provided separately to the Securities and
Exchange Commission. 









	 	
Further, each Party agrees to provide the other Party with a five (5) business day written notice that the Party intends to disclose confidential information as required per applicable law
and/or securities exchange rules. 

  

	 	9.	Costs. Each Party shall assume its own counsel costs, fees and expenses incurred in the preparation and negotiation of this Umbrella Agreement and the Supply Agreements, and the Parties shall not have the right
to claim for any compensation or damages for this cause. 

  

	 	10.	Modification of ESA; Incorporation of Certain ESA Provisions. The Parties acknowledge that all terms and provisions of the ESA, except as expressly modified by this Umbrella Agreement, remain in full force and
effect. The Parties further agree that Article 5 (Dispute Resolution), Article 6 (Indemnification), Article 7 (Default; Termination), Article 8 (Representations and Warranties), Article 9 (Confidentiality), and Article 10 (Miscellaneous) of the ESA
are incorporated by reference in and as part of this Umbrella Agreement, mutatis mutandis, but only to the extent they do not conflict with the express terms of this Umbrella Agreement. 


 

	 	11.	Term. This Umbrella Agreement shall expire upon the earlier of (i) the execution of Supply Agreements for each of the [***],[***] and [***] Projects, or (ii) December 31, 2015. 


 

	 	12.	Binding Effect. Seller and Owner agree that the obligations of the Parties set forth herein shall constitute legally binding commitments. 


 

	 	13.	Choice of Law: Dispute Resolution. This Umbrella Agreement shall be governed by the laws of the State of New York without regard to choice of law principles. Any claim, requirement, or dispute arising from this
Umbrella Agreement shall be irrevocably submitted to the exclusive jurisdiction of the state or federal courts located in New York City, New York. 

  

	 	14.	Assignment. Neither Party shall have the right or power to assign this Umbrella Agreement in any way without the other Party’s express written consent, which shall not be unreasonably withheld. Any purported
assignment made in violation of this paragraph shall be void. 

  

	 	15.	Expiration of Umbrella Agreement; Survival of Certain Provisions. In the event that the Umbrella Agreement expires or otherwise terminates, paragraphs 1, 7, 8, 13 and this paragraph 15 shall survive
notwithstanding such termination. 

  

	 	16.	Default; Termination; Damages. Notwithstanding anything to the contrary set forth herein, the Parties expressly exclude and waive any and all special, punitive, Indirect or consequential damages arising out of,
resulting from or in connection with the performance or non-performance of this Umbrella Agreement, including, but not limited to, loss of profit or business interruptions, howsoever caused, and whether or not foreseeable as of the Effective Date,
except if such damage is caused by fraud, willful misconduct or gross negligence.
