Investment guru Warren Buffett topped The Chronicle of Philanthropy’s annual list of the biggest charitable donations in 2023, with his $541.5 million gift to the Susan Thompson Buffett Foundation, named for his first wife, who died in 2004.

The 2023 list of gifts from individuals or their foundations totaled more than $3.5 billion. Four universities received big gifts, along with four scientific research institutes and a health-care system. The other gifts went to a family foundation and a racial justice group. The list has 11 gifts because of ties. Eight of the donors are multibillionaires, and their combined net worth is $305.1 billion.

Buffett’s gift is followed on the list by a donation from the mathematician and hedge-fund founder James Simons and his wife, Marilyn. The couple gave $500 million through their Simons Foundation to the State University of New York at Stony Brook.

The calendar flipped to 2024 on Monday, but Massachusetts still has not gotten any power from the Vineyard Wind 1 offshore wind farm, the second time the project has failed to meet the “first power” target set by top officials.

A spokesman for Avangrid, which along with Copenhagen Infrastructure Partners makes up the Vineyard Wind 1 joint venture, said Tuesday morning that the first of the project’s 62 turbines generated power Sunday evening but that more testing was required before any wind power could be transmitted to the grid. The spokesman gave no new specific timeline for the delivery of first power.

“We are currently working through all the required tests, both internal processes and with ISO New England, and synchronizing all components to deliver power to shore soon,” he said.
