Hydroelectric Power Leading the Way in Pakistan

Pakistan’s Water and Power Development Authority (Wapda) said it supplied 31.804 billion units of hydroelectric power to the national grid in 2013-2014. This is compared to 29.560 billion units for the previous years—a decrease of 1.524 billion units.

“This additional contribution of low-cost electricity helped the national exchequer save about Rs24.38 billion, which otherwise would have been spent on generating an equal volume of electricity from costly imported oil,” a Wapda spokesperson said.

Hydroelectric is also the cheapest form of energy the country has. This year, generation of hydroelectric power cost roughly Rs1.50 per unit, whereas the average unit cost for imported furnace oil was Rs16.

The country’s largest hydroelectric power station, Tarbela, produced 15.138 billion units in 2013-2014, which is an increase from 2012-2013’s 14.755 billion units.

Mangla, which is the 9th largest damn in the world, recently completed its capacity-increasing project, and generated 5.725 billion units in the same year period, compared to 4.576 for the previous period.

Wapda accounts for at least a third of the country’s hydroelectric power at about 7,000 megawatts generated. According to them, it’s the cheapest, cleanest, and most environmentally-friendly way of generating electricity. The method is becoming increasingly popular in the country.

This week, Prime Minister Nawaz Sharif announced that ground officially broke on the 4,320MW Dasu hydropower plant.

The plant is on the Indus River and will be located about 240km upstream from Tarbela.

The Indus River is an untapped resource of hydroelectric potential, with estimates placing it as having a potential to generate up to 40,000MW.

Drax advances biomass strategy with Pinnacle acquisition

Drax is advancing biomass following Pinnacle acquisition it reported in a trading update

Drax' recently completed acquisition of Pinnacle more than doubles its sustainable biomass production capacity and significantly reduces its cost of production, it reported in a trading update.

The Group’s enlarged supply chain will have access to 4.9 million tonnes of operational capacity from 2022. Of this total, 2.9 million tonnes are available for Drax’s self-supply requirements in 2022, which will rise to 3.4 million tonnes in 2027.

The £424 million acquisition of the Canadian biomass pellet producer supports Drax' ambition to be carbon negative by 2030, using bioenergy with carbon capture and storage (BECCS) and will make a "significant contribution" in the UK cutting emissions by 78% by 2035 (click here).

Drax CEO Will Gardiner said its Q1 performance had been "robust", supported by the sale of Drax Generation Enterprise, which holds four CCGT power stations, to VPI Generation.

This summer Drax will undertake maintenance on its CfD(2) biomass unit, including a high-pressure turbine upgrade to reduce maintenance costs and improve thermal efficiency, contributing to lower generation costs for Drax Power Station.

In March, Drax secured Capacity Market agreements for its hydro and pumped storage assets worth around £10 million for delivery October 2024-September 2025.

The limitations on BECCS are not technology but supply, with every gigatonne of CO2 stored per year requiring approximately 30-40 million hectares of BECCS feedstock, according to the Global CCS Institute. Nonetheless, BECCS should be seen as an essential complement to the required, wide-scale deployment of CCS to meet climate change targets, it concludes.
