During his brief, troubled tenure heading New York City Opera a decade ago as it was hurtling toward bankruptcy, the visionary European impresario Gerard Mortier commissioned Charles Wuorinen to write an opera based on “Brokeback Mountain.” But Mr. Mortier left the company almost before he began, and his American opera eventually had its premiere in Madrid.

Next season “Brokeback Mountain” will finally make its way to New York, to the opera company that commissioned it. The new group that reorganized City Opera and brought it out of bankruptcy announced Wednesday that it would give “Brokeback” its United States premiere in the spring of 2018, at the end of its second full season back in the business of staging operas.

“If not us, who is going to do it?” Michael Capasso, the company’s general director, said in a telephone interview. He noted that Mr. Wuorinen would be celebrating his 80th birthday next year, and that the Met Orchestra was planning to premiere a new work of his at Carnegie Hall.

Mr. Capasso said that the next season “checks the boxes” that he envisions for the rebuilt company. The season will open Sept. 6 with an old favorite, Puccini’s “La Fanciulla del West,” at Jazz at Lincoln Center’s Rose Theater. The company will continue its Ópera en Español series with a mariachi opera, José Martinez’s “Cruzar la Cara de la Luna.” It will bring back a relative rarity, Montemezzi’s “L’Amore dei Tre Re.”
