Significance Turkey stands to lose 21% of its import portfolio during the peak winter demand period. Take-or-pay gas import contracts signed two decades ago are coming to an end, and renewal is proving far from straightforward as exporters seek to leverage Turkey’s weak position to secure favourable terms. Impacts Cheaper gas on better terms would help Turkey’s chronic current account deficit. Ankara is keen to avoid further confrontation with Washington in case it puts further pressure on the lira in the run-up to elections. Balancing relations with Washington and Moscow and securing cheap, reliable gas supplies would be a major feat but may prove impossible.


The implementation of DSM programs is likely to introduce improvement in the efficiency of power systems, reduce financial burdens on utilities to build new energy facilities, improve the environmental situation, and lower the cost of delivered energy to consumers; thus lowering O&M costs as well as consumer bills, enhance system reliability by reducing power shortages and power cuts, improve the national economy by improving the value added of the electricity sector, and increase job creation and new business ventures.

Subject Regional power outlook for West Africa. Significance The West African Power Pool (WAPP), institutionalised in 2001, aimed to create a regional power market large enough to attract private investment. Among its 14 member states, WAPP boasts considerable energy resources. Progress has been slow, with chronic power shortages reflecting decades of under-investment in national sectors. Impacts With the exception of hydroelectricity, renewable energy will likely augment not replace traditional power, eg, coal and gas-based. However, 'off grid' renewable electricity generation and transmission systems may be increasingly used for powering remote locations. Facilities such the Sustainable Energy Fund for Africa will need to fund many renewables projects initially for them to be viable.


Subject Pakistan's LNG imports and natural gas supply. Significance Pakistan in July claimed it could become one of the top five purchasers of liquefied natural gas (LNG) by 2022. The country is looking to address growing gas demand and reduce capital outflows for fuel oil and diesel imports; regasification facilities are required to convert LNG back to natural gas at atmospheric pressure. Impacts Fewer power shortages would decrease protests, especially prevalent in summer months, over blackouts. Pakistan’s natural gas vehicle sector could see a rejuvenation, curbing gasoline and diesel demand. Increased LNG use in domestic fertiliser production will reduce urea imports.

AbstractPlanetary exploration requires a balance between preemptive planning and financial feasibility. The risk of mid-mission equipment failure, power shortages, or supply depletion incentivizes precautionary measures, but the financial strain of sending unnecessary mass into space limits this practice.To balance the two, our team explored the advantages of biological solutions, namely the self-sustaining abilities of low-mass organisms, to make planetary exploration more self-sufficient and economical. Prioritizing repair over replacement, we are developing self-healing materials embedded with Bacillus subtilis. For longer-lasting energy, we are designing a “biobactery” using linearly oriented Escherichia coli to generate power. For renewable materials, we are engineering bacteria to synthesize and degrade rubber. Individually, these projects offer sustainable alternatives for repair, power, and materials. But when combined, these consolidated insights can provide us with the power to get to Mars and resources to sustain us while we’re there.

<abstract> <p>Power shortage is a severe problem in developing countries that are rolling to blackout, but today smart grids have the scope to avoid entire blackouts by transforming them into brownouts. A brownout is an under-voltage condition where the AC supply drops below the nominal value (120 V or 220 V) by about 10%. In a power system network, power shortages or disturbances can occur at any time, and the reliability margin analysis is essential to maintain the stability of the system. Transmission reliability margin (TRM) is a margin that keeps the network secure during any occurrence of disturbance. This paper presents a new approach to compute TRM in the case of brownout. The detailed assessment of TRM largely depends on the estimation of the available transfer power (ATC). In this method, the ATC of the system is calculated considering the effect of alternating current (AC) and direct current (DC) reactive power (Q) flow (DCQF). The entire procedure is carried out for the multi-transaction IEEE-6 bus system, and the results are compared to the current efficiency justification method. Numerical results demonstrate that the proposed technique is an effective alternative for calculating the TRM and is valid compared to the existing technique.</p> </abstract>
