After years of hydro push, Arunachal begins scrapping dam projects

22 projects worth 3,800 MW terminated and 46 projects worth 8,000 MW had been served notices, says Chief Minister Pema Khandu

More than a decade after his father Dorjee Khandu ushered in a “dam revolution”, Arunachal Pradesh Chief Minister Pema Khandu has begun scrapping hydro-power projects for non-performance.

The Chief Minister, inaugurating the State’s first community-managed mini hydroelectric project at Dikshi in West Kameng district on September 13, said his government terminated 22 projects worth 3,800 MW while another 46 projects worth 8,000 MW had been served notices.

“These projects have not progressed and people have lost confidence in them. The government is reviewing the hydro-power projects periodically and action will be taken against the power developers found non-performing,” Mr. Khandu said.

Arunachal Pradesh was among 16 States identified during the Atal Bihari Vajpayee government for an ambitious plan in 2003 to make India produce 50,000 MW or hydroelectricity by 2017. This north-eastern State bordering China’s Tibet, accounting for the bulk of the proposed installed capacity was the first off the blocks for the hydro-power “gold rush”.

Agreement spree

A State hydro-power policy drawn up in 2007 saw Arunachal Pradesh sign agreements with both public sector and private sector players. Deals for 142 dams – their capacity ranging from 4.50 MW to 4,000 MW – on virtually all rivers and streams were inked by 2015.

In July 2015, former Congress Chief Minister Nabam Tuki told the State Assembly that Arunachal Pradesh received ₹1,495.6 crore as upfront money and processing fees from agreements signed with 159 companies for projects with installed capacities of 47,000 MW. The upfront money was charged per MW.

Local tribal groups and environmentalists across Arunachal Pradesh and Assam – which fears a massive downstream effect of the proposed dams – stalled most of the mega projects while a few such as the 2,000 MW Subansiri Lower being built by the NHPC has been lying incomplete since 2011.

Over the years, though, the Khandu government has been inclined towards smaller, sustainable hydroelectric projects. “It is time to change our mindset. Clean and green energy can change the economy of the State and the region,” Mr. Khandu said.

Kulsi dam

Meghalaya’s push for the Kulsi multi-purpose dam, declared a National Project, along the Assam-Meghalaya border, has unnerved the residents of 33 villages in Assam.

The project has been in limbo for almost a decade, but a consensus between the Assam and Meghalaya governments has paved the ground for a detailed project report. The dam is proposed on the Kulsi, a river where the endangered Gangetic river dolphins from the Brahmaputra breed, near Ukiam, a village about 75 km west of Guwahati.

The proposed capacity of the Kulsi project has not been specified, but it entails a 62m high concrete dam on the inter-State border. The project is estimated to cost ₹1,460 crore and would affect 15.55 sq km of land in Assam and 5.75 sq km in Meghalaya due to reservoir submergence.

“We cannot let our homes and farmlands be destroyed. The dam will be built over our dead bodies,” said J.R. Marak, the president of a committee involving all the villages.

NHPC likely to begin construction of 2 GW Lower Subansiri hydro plant in October

State-run hydro power giant NHPC is likely to begin construction of the 2,000 MW Lower Subansiri power plant in October this year as it has received the requisite approval from the Assam government, an official said.

NHPC had inked a memorandum of agreement (MoA) with Arunachal Pradesh for setting up the project in 2010. However, since the project falls in the territories of both Arunachal Pradesh and Assam, the latter’s approval was needed as well.

“NHPC inked MoA with Assam on August 23, 2019 for Lower Subansiri project. As you know, the National Green Tribunal (NGT) had given go-ahead to the project on July 31, 2019, and NHPC is expected to begin construction of the plant immediately after monsoon season is over by October this year,” the official said.

Developers of power projects are required to sign MoAs with the respective states for setting up plants in their territories.

The Lower Subansiri project has been stuck for the past eight years due to various issues. The run-of-the-river project on the Subansiri, a tributary of the Brahmaputra river, is mostly situated in Arunachal Pradesh. However, some parts of the submergence area fall in Assam.

Work on the project is expected to be completed in three-and-a-half years with a total expenditure of Rs 20,000 crore (on completion).

The official said to allay safety fears, the dam has been designed and strengthened to withstand seismic activity up to a magnitude of 8 on the Richter scale, which makes it one of the strongest dams in India.

Work on the Subansiri project was started in 2006, but it came to a halt in 2011 due to various issues.

In 2013, the NGT stayed any further work on the project. Thereafter, the project was examined from every angle, be it safety or environmental issues, by national and international experts.

Finally, the project got clearance from all the agencies, including the Ministry of Environment, Forest and Climate Change. Recently, the NGT also gave its nod for the construction of the project.

The project is located near North Lakhimpur on the border of Aruncachal Pradesh and Assam. The estimated annual energy generation from the project is 7,421 million units in a 90 per cent dependable year.

Hydro power is among the cleanest sources of green power. It is essential for meeting climate commitments and ensuring grid stability in view of anticipated large scale integration of infirm ..

integration of infirm renewable energy from sources like solar/wind.

The hydropower sector has been going through a challenging phase. The share of hydropower in the total capacity has declined from 50.36 per cent in the 1960s to around 13 per cent in 2018-19.
