Pakistan to soon set up world's largest solar park

Pakistan to soon set up world's largest solar park

Islamabad [Pakistan], Nov.30 : Pakistan will soon have the world's largest solar park of 1,000 megawatts, the country's Minister of Climate Change Zahid Hamid has said.

Addressing a press conference here, Hamid briefed them about Pakistan's participation in the COP22 Conference in Morocco recently, which provided an opportunity to highlight the significant achievements made by the country to address the impact of climate change, reports the Express Tribune.

Hamid said the world community was informed that Pakistan's contribution to global warming was minimal as "we emit less than one percent of the annual global greenhouse gas emissions. Yet we are ranked amongst the top 10 countries that are most vulnerable to climate change."

The world community was also informed that Pakistan faced several major risks pertaining to climate change, including glacier melting, variable monsoons, recurrent floods, rise in sea levels, higher average temperatures and higher frequency of droughts.

Millions of people had been affected and a colossal damage was caused on a recurring basis, he said.

"These threats pose major survival concerns for Pakistan, particularly in relation to water security, food security and energy security," Hamid said, adding these threats also had enormous adverse consequences for all socio-economic sectors, limiting the country's ability to promote sustainable growth and development.

The minister emphasised that Pakistan as a responsible member of the global community had taken substantial steps, especially during 2016, to tackle the threat of climate change.

He termed the launch of Rs2-billion Prime Minister's Green Pakistan Programme, which would be implemented across the country, as a historic initiative.

Pakistan has developed the National Sustainable Development Strategy and is perhaps the first country in the world whose National Assembly passed a unanimous resolution adopting the SDGs as its own national development agenda, said the minister. (ANI)

Coal and oil demand ‘could peak in 2020’

Coal and oil demand ‘could peak in 2020’

Solar power and electric vehicles will wreak havoc on the energy sector, say analysts from Carbon Tracker and Grantham Institute, in contrast to rosy industry forecasts

Fossil fuel giants are vastly underestimating the disruptive power of solar panels and electric cars, which could see coal and oil demand peak by 2020.

That is the conclusion of a report by the Carbon Tracker Initiative and Grantham Institute published on Thursday.

Energy companies pursuing business as usual are in for a rude awakening, by this analysis, with many mines and oil fields likely to become surplus to requirements.

Based on dramatic cost reductions in recent years, the model foresees these two technologies taking a 10% chunk of market share from carbon majors in a decade. That may not sound like much, but was enough to devastate the US coal sector.

“If people are just waiting on policy to happen, they could get bitten by clean technology coming up behind them,” said James Leaton, an author of the report.

Solar panel costs have fallen 85% in the past seven years and car battery costs 73%. Despite these advances, the traditional energy companies continue to forecast linear growth at best.

BP predicts electric cars will make up 6% of the market by 2035. Carbon Tracker reckons a third is feasible.

Exxon Mobil expects all renewables to supply 11% of electricity in 2040. Carbon Tracker says solar alone could produce 23%.

It is not enough to meet the Paris Agreement upper limit on global warming of 2C, but bends the curve to 2.4-2.7C, compared to 3-4C under industry scenarios. Policies targeting other sectors would bring the international climate goal within reach.

Railways explore Options to buy distressed Power Projects to cut Energy Costs

Railways explore Options to buy distressed Power Projects to cut Energy Costs

New Delhi: Indian Railways is exploring options to buy distressed power projects as the nation’s largest consumer of electricity seeks to cut energy costs.

A panel headed by Ajay Shankar, a former secretary of the department of industrial policy and promotion, has suggested, among options, that the national transporter consider buying such assets. The panel was constituted by the Indian Railways earlier this year to review the functioning of the railway board’s public-private partnership cell.

The abundance of distressed projects in the power sector may provide Indian Railways, which needs about 12 billion units of electricity a year, an attractive opportunity to buy assets at a cheap price. Companies, which started building power projects in anticipation of faster economic growth about five years ago, had to weather a slowdown that caused growth to sink below 5%. In addition, several of these power plants are beset with fuel shortages and high borrowing costs that have hurt the ability of the companies to repay creditors.

Acquiring such assets fits in with the Indian Railways’ plan to set up a transmission system to wheel power for its network.

Indian Railways’ power consumption is growing at an average 5% a year and its power bill is estimated at Rs.12,500 crore in the year to 31 March.

“The plan is at a conceptual stage,” said a person aware of the development, requesting anonymity.

Indian Railways is considering options such as buying equity in distressed power assets and new power projects and setting up captive plants, said another person who also didn’t want to be identified.

Buying out an asset will, however, pose the problem of asset management for the Indian Railways, said Anil Razdan, a former power secretary. “Railways are already in a joint venture with NTPC for a power project and will have to develop their full fledged asset management company. The choices for railways can be to either develop their own expertise, set up a joint venture with NTPC or tie up with a power trader for their electricity needs.”

Stalled power projects are also a major concern for bankers. As of 31 March, 607 projects with investments worth more than Rs.4.85 trillion were classified as stalled, according to data collated by the Centre for Monitoring Indian Economy Pvt. Ltd. Of these, 33 projects, representing over Rs.1 trillion in investment, were in the electricity segment.

“The stressed project developer and the financial institutions would certainly feel relieved,” said Razdan.

Railway minister Suresh Prabhu, in his February budget, unveiled a plan to investRs.8.5 trillion in the railways over the next five years, with a focus on capacity augmentation and modernization. The government hopes to leverage the public-private partnerships to improve its freight business and investment in its infrastructure.

Queries emailed to a spokesperson of the Indian Railways remained unanswered till press time.

A senior Railways Board official, requesting anonymity, confirmed the development. “Buying power generation assets have been suggested by the Ajay Shankar committee. We are evaluating the options,” he said.

Cash-strapped state electricity boards (SEBs) have been unwilling to procure electricity, given the low tariffs they earn for power supply, slow progress in reducing losses and higher power purchase costs. SEBs are laden with debts ofRs.3.04 trillion and accumulated losses of Rs.2.52 trillion. This, in turn, has hit power generation projects.

Power projects with a combined capacity of 46,000MW are facing viability issues in the absence of long-term electricity buyers and because of inadequate fuel supply, their developers having bid aggressively to win the projects and coal block links, according to a 28 July report by rating company Crisil Ltd.

“Of this, 36,000MW are coal-based projects within which tariff under-recovery has impacted 20,000MW of capacities, while the rest are reeling because of inadequate feedstock and poor electricity off-take by discoms,” the report added.

The railways plans to source 10% of its electricity needs through renewable energy sources by 2020 and signed agreements with the ministries of power and renewable energy on Wednesday for cooperation in electricity transmission, energy efficiency and promotion of green energy.

The national transporter plans to reduce electricity bills by nearly one-third by seeking competitive bids from power producers, sourcing from electricity exchanges and reaching bilateral arrangements. This plan was articulated in this year’s railway budget.

As part of this strategy, it is trying to take advantage of its position as the largest consumer of power in the country to bring down its electricity costs by calling for bids from power producers to supply 1,010 MW of electricity over three years.  By calling for competitive bids, the railways expects to benefit from lower tariffs.

The transporter is seeking to reduce its electricity cost to less than Rs.5 per unit from the present average of around Rs.7 per unit.

Konkan Railway switches to LED in all its 91 Tunnels

Konkan Railway switches to LED in all its 91 Tunnels

Ratnagiri (RN): Contributing on a mega scale to energy conservation and environment preservation through its daily operations, Konkan Railway has now changed all the light fittings in its 91 tunnels to LEDs, thus reducing the Carbon foot-print considerably. Konkan railway has also taken to plantation in a big way on an annual basis along its entire route which has given it the unique identification of “Garden Railway”.

The LEDs installed in all the tunnels are 24W which consume one-third the energy consumed by 70W HPSV bulbs but gives double the illumination. It has not only conserved energy but also increased safety levels inside tunnels, given the fact that 84 kms of KR route stretch is covered with tunnels. Konkan Railway has also provided energy saver equipments in all its tunnels which controls current voltage so that the current drawn is less.

Apart from this, small initiatives like phasing out of all incandescent bulbs from the railway premises and replacing with more energy efficient T5 fittings, change of resistance-type fan regulators used in KR to electronic ones etc, are reaping benefits to KRCL and environment at large. KR has switched over to Green Energy with installation of solar plants at Ratnagiri and Karmali stations, installing solar geysers at all its Running Rooms and rest houses.

As many as 53,699 saplings of various types of plants were planted in last one year by KR along its route and 28,000 are planned to be planted during the oncoming monsoon. KR has taken to planting an average of 30,000 saplings per year on its route which is giving a Green Railway look to KR route that is held in awe by Nature lovers. A specific type of Vetiveri grass was also planted on the route to hold the soil together.

Konkan Railway’s Roll-on Roll-off service, which carries loaded goods truck on railway wagons, saving precious fossil fuel, is already proved to be a successful innovation.
