The ACT has sent a six-member delegation to New Delhi to join three-day "mahadharna" being organised by anti-dam activist Medha Patkar's National Alliance for People's Movement (NAPM) from April 28-30.
The mahadharna is being organised to highlight the adverse effects of dams and hydel power projects across the country including those in Sikkim.
The ACT has been agitating against Dzongu Hydel Project since June 20, 2007.
Patkar had promised to articulate the ACT's demands at the national level and invited the protesters to New Delhi to join the NAPM's dharna and campaign on the environmental issues.
She had expressed "pain" and "anguish" at the struggle of the indigenous Lepcha people to protect "holy" land and natural resouces in Teesta valley.
Sikkim Chief Minister Pawan Kumar Chamling was charged with ignoring the rightful claims of the local people by deciding to go ahead with the power project during her visit.
Medha, who spearheaded Narmada Bachao Andolan, had questioned the wisdom of the state government to construct 26 hydel projects in the Teesta valley despite the mountaineous region being a earthquake-prone zone.
