PM Imran launches Green Euro bond for WAPDA's Mega Projects (Diamer Basha and Mohmand Dam Projects)

Prime Minister Imran Khan formally launched Pakistan’s first Green Euro bond in Islamabad on Monday.
The Green Euro, called Indus Bond, has been issued by Water and Power Development Authority to raise $500 million for financing Diamer Bhasha and Mohmand dams.

Addressing the launching ceremony, Prime Minister Imran said the government has planned to construct ten dams in ten years to meet water needs and produce clean energy.

He said these two water reservoirs will produce 10,000 megawatts of clean and environment friendly electricity.

Pakistan is one of the most affected countries by climate change and global warming in the world, he said and added to address this challenge, the government is effectively working on tree plantation drive under ten billion tree tsunami programme.

The prime minister said this programme will considerably improve living standards of the people besides promoting tourism and reducing pollution. The target of one billion trees has been successfully achieved, he continued.

He said 15 national parks are being set up to protect and preserve the natural environment.
The government is working on a long-term planning to save the next generations as such policies are imperative for development of the country, the prime minister maintained.

Referring to the public welfare programmes initiated by the government, he said unified curriculum is being introduced to ensure quality education across the country.

The PTI government has launched exemplary healthcare programme to provide universal health coverage to masses, he said, adding that 100 percent population of Khyber Pakhtunkhwa has been provided health coverage while Punjab will achieve the target this year.

The formal operation of the Matiari-Lahore transmission line will begin on Sept 1.

LAHORE: Testing for the evacuation, transmission, dispatch and distribution of 2,200MW of electricity by the country’s first high voltage direct current (HVDC) Matiari-Lahore transmission line was successfully carried out on Thursday, paving the way for the launch of the line’s formal operation on Sept 1, a revised date for the commercial operation of the mega project being completed under the China-Pakistan Economic Corridor (CPEC).

“Since the line has been designed to evacuate 4,000MW from the power plants in south (Sindh) in alternative current (AC) mode, convert it in direct current (DC) at a convertor station at Matiari (Sindh, near Hyderabad), transport/transmit it in DC mode and dispatch it to the distribution systems of the power distribution companies after converting it from AC to DC at a convertor station near Bhai Pheru (Lahore), the transmission and despatch test of 2,200MW is a major test ahead of the commercial operation of the line set for Sept 1,” a spokesman for NTDC told Dawn.


He said the 660kV HVDC line is new technology in Pakistan being completed under the ‘build, own, operate and transfer basis by the Matiari-Lahore Transmission Company under the supervision of the NTDC. From Sept 1, the official said the line would start evacuating, transmitting and dispatching of 4,000MW to the urban load centres in central and northern parts of the country.

“After 25 years operation, the project will be handed over to the NTDC,” he said.

In April, this year, the decision for the launch of commercial operation of the line from Sept 1 had been taken after various technical and contractual issues were amicably resolved between the Pak Matiari-Lahore Transmission Company Limited (PMLTCPL) and the NTDC.

The project agreements were signed between the NTDC and the PMLTCPL at the PM house on May 14, 2018, and its construction was launched in December 2018. Currently, the construction of the project is almost complete and the project is at advanced stages of testing and commissioning, and more than 95pc testing and commissioning stands completed.

Whats the benefit? Reduce line losses? If so , how much?

High voltage direct current (HVDC) Transmission

Electricity is typically transferred between various regions of the country over transmission lines via alternating current (AC). A less common form of transmission is high voltage direct current (HVDC).

When the electricity grid was developing in the late 1800s, a great debate ensued over which type of current was best for transmitting electricity. Alternating current ultimately won since a transformer could be used to increase or decrease voltages, and no similar option existed at the time for direct current.


Advantages and Disadvantages of HVDC

Alternating current travels as a wave, and is constantly changing direction (60 times per second, defined as 60 hertz, in North America). Since direct current does not involve oscillation, it decreases losses and allows electricity to be transmitted more efficiently.

However, the cost of the substation equipment needed to convert DC electricity back to AC at both ends of the transmission line is expensive. Since the initial cost can be prohibitive, HVDC transmission is usually only preferred for long distances. Over their lifetime, long-distance transmission lines can save operators money because of their efficiency.

Other advantages of HVDC include lighter and cheaper towers (since DC cable can carry more power than AC cable), and it does not generate or absorb any reactive power, eliminating the need for reactive power compensation.

In addition to equipment cost, another disadvantage for HVDC involves heat losses that occur in the converter substation, which requires an active cooling system. Also, inverters used in converter substations have limited overload capacity. A shortage of proficient electrical engineers to maintain and operate HVDC lines and equipment also remains a longstanding challenge, according to a recent report on the HVDC market.


Growth of HVDC Transmission Systems

While AC transmission remains the dominant form of transmission in the U.S., HVDC transmission systems have been growing in recent decades as technological developments have helped reduce costs. HVDC transmission is also seen as a solution for distributing renewable energy (such as wind and solar) from remote areas where it is easily generated to more densely populated areas of the country.

The U.S. has 20 HVDC transmission facilities, including the Pacific DC Intertie, which became the first major HVDC link in the U.S. when it was commissioned in 1970. The 845-mile line transmits electricity between the Pacific Northwest and the Los Angeles area, moving surplus electricity from one region to the other as seasonal demands shift. Since its original construction, modernizations have more than doubled its DC capacity to 3,100 MW.

Nepra for expanding renewable energy footprint to 30pc

The Newspaper's Staff
June 5, 2021

KARACHI: The National Electric Power Regulatory Authority (Nepra) intends to enhance the renewable energy footprint to 30 per cent over the next 10 years from the current 3pc of Pakistan’s overall generation capacity of over 35,000MW, Nepra Chairman Tauseef H. Farooqi said on Friday.

Addressing a live webinar on “Pakistan’s Energy Transition and the Road Ahead” hosted by K-Electric and Nepra, he said the current share of hydropower at 30pc should be included in the renewable energy mix which would enable Pakistan’s total progress in the renewable energy space to exceed 60pc in next ten years. This should result in an environmentally friendly and affordable energy mix in the country, he added.

“For renewable industry to innovate and thrive, Pakistan needs a transition in its generation, transmission and distribution system. Nepra has been constantly working to bring that very change and its actions are louder than words,” Mr Farooqi highlighted.

In her opening remarks, KE Chief Strategy Officer Naz Khan revealed that currently renewables have around 250MW of share in the utility’s total energy mix including almost 150MW from wind and 100MW from solar energy. She added that additional projects are in pipeline to increase the share of renewables to 350MW.

While moving accordingly as per guidelines and policies set by the federal government, KE looks forward to continuously increasing the share of renewables in its energy mix in the buildup to 2030, she said, adding that KE has stepped into the renewable energy space with the launch of its first ever subsidiary – K-Solar – which is another step to a greener and more sustainable future for our future generations.

Alternate Energy Development Board CEO Shah Jahan Mirza said that allowing purchase of power from solar and wind energy projects through competitive bidding remained one of the strong features of their new policy. This had never been done in Pakistan before, he claimed.

State Bank of Pakistan (SBP) Director of IH&SMEFD Dr Mian Farooq Haq said the central bank had introduced a financing scheme in 2016 to lend support in addressing climate change issues and to promote renewable energy.

The scheme is continuing to offer varied financing options ranging from Rs400 million to Rs6 billion for a broad category of entities and individuals. As of February 2021, financing of around Rs36bn has been extended to over 500 projects,” he added.
