K-Electric to build 2×660 MW Thar coal-fired power project
Signs multi-party MoU to add indigenous
resource-based power generation
K-Electric signed a Memorandum-of-Understanding (MoU) with the Sindh government, Oracle Power, and PowerChina for the potential development of a 2×660 MW coal-fired power project based on Thar coal, the company’s website said.
The company claims it is committed to increasing reliance on indigenous sources of energy production to provide access to affordable energy for all.
KE was represented by its Chief Executive Officer (CEO) Moonis Alvi, while Secretary of Energy Abu Bakar Ahmed was present from the provincial government, Naheed Memon, CEO of Oracle Power, and Cheng Qiang from PowerChina.
Oracle Power is an international natural resource and power project developer listed on London’s stock exchange, while PowerChina is a Fortune 500 listed integrated construction group that has completed over 40 various projects in Pakistan with a total contract value of approximately USD 6 billion, and an additional 43 projects worth USD 7.5 billion currently under execution, company’s communication on its portal says.
Sindh Minister for Energy Imtiaz Shaikh who spoke on the occasion stated “Electricity is a fundamental driver of development and progress, and this collaboration is a big step in this direction. Once operational, this project will immensely benefit the entire province which is why we are committed to providing our full support until its maturity.“
The main objective of the MoU is to provide a collaborative framework for the partnering parties, setting the stage for the establishment of this ambitious power plant. For KE, this move aligns with the company’s forward-looking plan of enhancing its generation through the addition of low-cost, indigenous fuel-based power.
The company has shared its vision of adding a total of 2,200 MW to its generation capacity by 2030 and increasing its share of renewable energy to 30% of the overall mix. The inclusion of such generation capacity also aligns with KE’s future projections for the city, which envisages a customer base of 5 million using 5,000 MW of electricity by FY30.
CEO KE Moonis Alvi also shared his excitement on the occasion, stating that “As a company, our ambition and initiatives are towards achieving net zero and tackling the energy trilemma which balances reliability, affordability, and sustainability of energy supply. Our current partnership and our future plans will greatly enable us to reduce our reliance on imported fuels. Moving forward, we are also enhancing our share of renewable energy in the generation mix to provide affordable and sustainable electricity to customers. These plans are further complemented by our comprehensive investment plan of PKR 484 billion, which will strengthen the network and deliver energy effectively to our growing customer base.”
CEO of Oracle Power Naheed Memon reiterated her company’s commitment to the development of the CPEC-listed 1320 MW coal-to-power project. She shared that Oracle has produced world-class feasibility reports which became benchmark documents for its development. Oracle Power is very pleased to have formed a strategic relationship with KE as a potential off-taker and the Government of Sindh as a facilitator and important stakeholder.
A representative from PowerChina shared that the development of the Thar Project is of great importance to Pakistan in the sense of utilizing the local coal resource. Oracle 1320MW Coal Power Project is listed as one of the priority energy projects under the China Pakistan Economic Corridor(CPEC). With the guidance and participation of the Sindh Government, together with KE and Oracle, PowerChina will provide support for the success of the project.
Earlier this year, KE also entered into an MOU with China Three Gorges South Asia Investment Limited (CTGSAIL) to collaborate on exploring renewable energy projects across the country. — PR
Pakistan, Afghanistan among
20 countries at risk of excessive rainfall
Over 42 countries to live with dry weather conditions and thus increase more poor
Food and Agriculture Organization (FAO) of the United Nations says the El Niño oceanographic phenomenon forecast will return in June 2023, following three years of La Niña and thus is expected to bring dry weather conditions in around 42 countries and excessive rainfall and possible flooding in over 20 countries including Pakistan.
The forecast, says the FAO report, suggests dry weather conditions in key cropping areas of Central America, Southern Africa, and Far East Asia, while excessive rainfall and possible flooding are foreseen in Near East Asia and East Africa.
In other words, as many as 42 countries will be at risk of dry conditions and may face drought and 20 countries are at risk of excessive rainfall.
The El Niño oceanographic phenomenon is a key driver of extreme weather events that pose high risks to global food security.
Already in 2022, the number of people facing acute food insecurity was projected to reach up to 222 million in 53 countries/territories, the highest level on record according to the latest Hunger Hotspots report, the UN body writes.
“The world experienced a third consecutive La Niña event in 2022 and early 2023, a rare occurrence that has happened only twice since 1950. La Niña events are commonly associated with wetter conditions in Australia and drier conditions in the United States of America, South America, and East Africa. Reflecting these typical weather patterns, widespread flooding occurred in Australia where also bumper wheat outputs were recorded in 2021 and 2022, while drought conditions curbed wheat and maize yields in the United States of America as well as in Near East Asian countries.”
According to the report, weather forecasts point to a transition to an El Niño state in the second half of 2023 and the rainfall patterns during El Niño events tend to be the reverse of La Niña.
This report primarily focuses on dry weather conditions, considering the significant impact that water stress has on agricultural production and that a larger area of cropland is affected by rainfall deficits compared to areas expected to receive above-normal precipitation.
“The analysis examines cereal crops, given their high share of calories in total food consumption, notably in low-income countries, and, therefore, their importance for food security. There are, in addition, hazards associated with El Niño-induced wetter conditions, primarily floods, and areas with a high likelihood of excessive rainfall are also mapped.”
The report says several countries in those regions expected to remain dry are currently suffering from economic instability, due to low economic growth, unsustainable debt levels, and foreign exchange shortages, which have contributed to high inflation rates.
In the event of an agriculture production shock, this economic instability could pose challenges for countries to increase needed imports.
It further says wetter conditions are normally conducive for agricultural production, excessive rainfall amounts raise the risk of flooding, with potentially negative repercussions for the agriculture sector through damage and losses of crops. Even without triggering floods, excessively humid conditions often raise the likelihood of an increased prevalence of crop pests and weeds, as well as outbreaks of crop and animal diseases.
The identification of croplands most susceptible to El Niño effects is intended to support preparedness and response planning to minimize the negative impacts on agriculture and food security. The inclusion of the cropping calendars is to provide additional guidance on the type of support that would be most suitable for these countries. Preparing for El Niño FAO has developed Anticipatory Action (AA) standard procedures to be followed in most countries at risk of being affected by El Niño in 2023/24, where food security is a major concern. For instance, there are active AA protocols in Burkina Faso, Chad, Niger, Madagascar, Malawi, Zimbabwe, the Philippines, Pakistan, and Central American countries. In addition, FAO is ready to implement agricultural and livelihood-based interventions, in coordination with governments and humanitarian partners, should the El Niño forecast materialize.

Mechanical Properties of Biomaterials
Biomaterials must not only be approved as biocompatible but also specially developed for their intended use inside a medical device. This is crucial when considering the mechanical characteristics that determine how a particular biomaterial performs. The Young’s Modulus, E, which represents a material’s elastic response to stresses, is one of the most important material properties. For the best compatibility between the device and the body, whether the device is implanted or mounted externally, the Young’s Moduli of the tissue and the device that is being connected to it must nearly match. Ductility is crucial for implanted biomaterials that might be exposed to temperature changes, such as dental implants. For the same reason that the tensile strength cannot be excessive, the material must be ductile. Ductility allows the material to flex without breaking and also prevents the concentration of stresses in the tissue as the temperature changes. For dental implants as well as any other rigid, load-bearing implants, such a replacement hip joint, the material’s toughness is crucial.
Another crucial characteristic that needs to be taken into account for medical devices that are embedded or fastened to the skin is the flexural stiffness, D. Flexural rigidity will affect how effectively the device surface can maintain conformal contact with the tissue surface. This is crucial for devices that measure tissue motion (strain), electrical signals (impedance), or are made to adhere to the skin without delaminating, such as epidermal electronics.
The ultimate tensile strength of the biomaterial often decreases as its elasticity rises, and vice versa. Neural probes are one use where using a high-strength material is undesirable; in these applications, the tissue will always break before the device does (under applied load) since the dura mater and brain tissue have Young’s moduli on the order of 500 Pa. When this occurs, irreparable brain damage may result; as a result, the biomaterial must have a low tensile strength if an applied load is anticipated and an elastic modulus that is less than or equal to that of brain tissue.
By matching the elastic modulus, it is feasible to prevent stress concentrations that can cause mechanical failure and limit movement and delamination at the bio interface between the implant and tissue. Tensile and compressive strengths, which define the maximum stresses a material can bear before breaking, are other crucial characteristics. They can be used to set stress limitations that a device may be exposed to inside or outside the body. It may be advantageous for a biomaterial to have low strength in some applications, while it may be desirable for a biomaterial to have great strength in some applications, such that it is resistant to failure when subjected to a load.
Due to their innate flexibility and adaptable mechanical qualities, polymers are some of the most often utilized biocompatible materials (or biomaterials). A small number of plastics, such as cyclic olefin copolymer (COC), polycarbonate (PC), polyetherimide (PEI), medical-grade polyvinyl chloride (PVC), polyethersulfone (PES), polyethylene (PE), polyetheretherketone (PEEK), and even polypropylene, are frequently used to make medical equipment (PP). The use of biodegradable materials advances ethics while simultaneously enhancing the biocompatibility of implantable technologies. When evaluating various biodegradable biomaterials, a number of characteristics, including biocompatibility, are crucial. Depending on their source and kind of extracellular matrix, biodegradable biomaterials can be either artificial or natural (ECM).
High toughness enables biomaterial implants to endure longer inside the body, especially when subjected to enormous stress or cyclically loaded stressors, like the pressures imparted to a hip joint when running. Toughness characterizes the material’s capacity to deform under applied force without shattering.
