Avangrid Has Ongoing Plans for Green Hydrogen, Solar and Offshore Wind Power
Avangrid is becoming an important player in the US renewable energy industry, with $38 billion in assets and a presence in 24 states. They are developing many offshore wind farms in the East Coast, including Vineyard Wind 1 (800 MW) and Park City Wind (804 MW), located in Massachusetts and Connecticut. However, Avangrid is also participating in major solar and battery projects in Nevada, along with California-based Primergy Solar.
Early in July, Avangrid also submitted several green hydrogen proposals, in response to an RFI issued by the US Department of Energy. Their proposals cover areas like clean transportation, renewable natural gas production, and green ammonia for industrial applications.
Avangrid’s Green Hydrogen Proposals for the US DOE
If approved by the US Department of Energy, the green hydrogen projects proposed by Avangrid would be located in Connecticut, New York, Maine, Oregon and Texas. The five proposals are summarized in the following table:
|Connecticut||20 MW electrolyzer and hydrogen storage facility, running mostly with offshore wind power.||Producing 2.9 million kg of hydrogen per year, saving 25,000 metric tons of CO2 emissions, while generating 400-800 jobs.|
|New York||Hydrogen production and distribution facility, operated by Rochester Gas & Electric (RG&E)||The project would focus mostly on green transportation, but the facility could be used for multiple purposes.|
|Maine||Hydrogen production facilities for Central Maine Power (CMP)||Using hydrogen for manufacturing applications, renewable natural gas production, and transportation.|
|Oregon||20 MW hydrogen electrolyzer for the Klamath Cogeneration Plant||Using surplus wind turbine capacity, and blending 2% green hydrogen with the power plant’s fuel supply.|
|Texas||Large-scale electrolysis plant at Corpus Christi.||Generating green hydrogen and ammonia for industrial applications, using surplus wind power from Texas.|
Avangrid can draw from the experience of the Iberdrola Group, which is currently building the Puertollano green hydrogen plant – the largest of its type in Europe. The plant will combine a 100MW solar array, a 20 MWh lithium-ion battery system, and a 20 MW hydrogen electrolyzer.
Avangrid’s Ongoing Plans for Solar and Wind Power
On July 26, Avangrid announced the sale of two large-scale solar and battery projects in Nevada, with a total capacity of 1,080 MW. The projects were sold to Primergy Solar, but Avangrid will continue to participate as a developer.
- Iron Point Solar combines a 250MW photovoltaic array and a 200MW 4-hour battery system, and will start operating in 2023.
- Hot Pot Solar is larger, with a 350MW array and a 280MW 4-hour battery. The project is set to open in 2024.
The goal of these two projects is replacing the 522MW North Valmy coal plant, which will close by the end of 2022. NV Energy has already included both solar + battery projects in their Integrated Resource Plan, presented to the Nevada Public Utilities Commission. Primergy Solar will be in charge of design, procurement, financing, construction, and the start of operations.
Avangrid is also planning the massive 2,500MW Kitty Hawk Wind project, located 27 miles from the Outer Banks in North Carolina. The project will use a 122,405-acre lease that was awarded to Avangrid Renewables in 2017, and it will have enough generation capacity for 700,000 homes. The first phase of Kitty Hawk, has a capacity of 800 MW – the same as Vineyard Wind 1 – and it will start construction in 2024.
North Carolina plans to install 2.8GW of offshore wind power by 2030, and 8GW by 2040. This is enough generation capacity for 2.3 million homes, and the state would be cutting its power sector emissions by 70%. Offshore wind power could bring an investment of $140 billion to NC over the next 15 years.
