Who Owns Avangrid?

Avangrid reports sustainability metrics under Iberdrola's annual sustainability report. The company's renewables subsidiary, Avangrid Renewables, operates 80 power facilities generating approximately 13,000 GWh of electricity in the first six months of 2025, equivalent to powering approximately 2.4 million U.S. homes from wind and solar alone.

Avangrid has committed to a carbon neutrality target for its own operations and participates in Iberdrola's group-wide net zero 2040 goal. Iberdrola is aligned with the Science Based Targets initiative and publishes annual climate disclosures under the TCFD framework. Avangrid's U.S. supplier investment of $4.3 billion in 2024, a 16% year-over-year increase, is tracked as part of the company's commitment to domestic economic development and supply chain resilience.

Avangrid Renewables' projects include Vineyard Wind 1, an offshore wind project off Martha's Vineyard, Massachusetts, which began generating electricity in January 2024. The project has a planned capacity of 800 MW, enough to power approximately 400,000 Massachusetts homes. The project has faced regulatory and permitting complications, detailed in the Recalls and Controversies section.

Avangrid's regulated utility subsidiaries operate under mandatory renewable portfolio standards in Connecticut, Maine, and New York, requiring increasing percentages of electricity delivered to customers to come from renewable sources. Compliance reporting is filed annually with state public utility commissions and is publicly accessible through each state's regulatory dockets.

Avangrid was named to TIME's America's Best Mid-Size Companies list for the second consecutive year in 2025. This list is compiled annually by TIME in partnership with Statista using employer reviews, revenue growth, and ESG criteria.

Avangrid Renewables' Vineyard Wind 1 project, a joint venture with Copenhagen Infrastructure Partners off the Massachusetts coast, became the first commercial-scale offshore wind project to generate electricity in the United States in January 2024. This was a documented first in U.S. offshore wind history.

Avangrid has received the ENERGY STAR Partner of the Year Sustained Excellence Award from the U.S. Environmental Protection Agency for multiple consecutive years, recognizing its energy efficiency programs in its regulated utility service territories.

Central Maine Power Billing and Reliability Controversy (2017-2022): Central Maine Power (CMP), Avangrid's regulated electric utility in Maine, faced one of the most significant utility controversies in New England in recent years. Following a customer billing system upgrade in 2017, CMP customers reported unexpected and large bill increases. A Maine Public Utilities Commission investigation found that CMP's billing system had errors and that the company had inadequate customer service processes. The PUC ordered CMP to pay refunds and imposed financial penalties. CMP also received poor reliability scores relative to peer utilities in NERC reporting benchmarks. The controversy contributed to a successful 2019 ballot initiative in Maine to create a consumer-owned utility, though subsequent votes have not resulted in CMP's replacement as of June 2026.

Vineyard Wind Turbine Blade Failures (2024-2025): Vineyard Wind 1, Avangrid Renewables' joint venture offshore wind project, experienced structural failures in turbine blades manufactured by Siemens Gamesa in 2024. Blade fragments washed ashore on Nantucket and Martha's Vineyard beaches. The Bureau of Ocean Energy Management ordered Vineyard Wind to pause operations and conduct inspections. Siemens Gamesa acknowledged the blade design issue. As of June 2026, Vineyard Wind is in a partial operational status while Siemens Gamesa replaces affected blades. The failures drew national attention to offshore wind blade manufacturing quality standards.

New England Clean Energy Connect Opposition (2021-2023): Avangrid's proposed high-voltage transmission line through Maine to deliver Canadian hydropower to Massachusetts, known as New England Clean Energy Connect (NECEC), was approved by Maine regulators but rejected by Maine voters in a November 2021 referendum. The Maine Supreme Judicial Court and subsequent legal proceedings created a prolonged dispute about whether the voter referendum was legally binding. Maine courts ultimately ruled in favor of the project, and construction resumed. As of June 2026, the line is in operation, though the controversy over the referendum outcome remains a point of contention in Maine energy policy.
