The main shareholders of NTR have asked the company to sell its US wind assets "as soon as possible" and initiate a share tender offer following the disposal.
Woodford Capital, One51 and Pageant Holdings, which own 71.5% of the NTR between them, have agreed to put the proposal to the company's board following an ongoing row over its strategy.
The board of NTR said it noted the agreement and was "pleased to note that the shareholders have come to a common understanding".
The firm said One51 - which owns almost 24% of NTR - and Pageant Holdings - which owns 9% - had both indicated they would sell their entire respective NTR holdings as part of a tender offer, depending on the price offered per share.
The company's biggest shareholder, Woodford Capital, said it did not intend to sell any of its shares under such an offer.
Tom Roche is chairman of both NTR and Woodford Capital.
In a statement NTR's board said it already had a process underway for the disposal of its US wind assets, adding that the company would "look favourably upon a liquidity process" subject to that being completed.
"Such a liquidity process would further augment the €400m returned to shareholders over the past six years, it said.
One51's chief executive Alan Walsh said he was "very happy that the shareholders have come to a common agreement" on the company's strategy and was "equally happy with the board’s response to our proposal".
"Now we just need to let NTR board get on with things," he said.
NTR operates US wind energy business Wind Capital Group and has targeted a European expansion of its business in recent times.
It also owns National Toll Roads and Celtic Anglian Water, which operates the Ringsend Wastewater Treatment Plant in Dublin amongst other facilities.
