The Cost

Purpose Over the past two decades, in developed countries a trend towards the liberalization and restructuring of the gas market has been observed. Today, restructuring is an ongoing process. In this study, a restructured natural gas market has been considered in which several regional distribution companies have ownership of the network and are competing against each other to gain more benefits. The main purpose of this study is to achieve efficiency and economic rationality in such a market through horizontal cooperation. Design/methodology/approach A restructured natural gas distribution network is modeled as a cooperative game to estimate the potential cost savings for various collaboration scenarios. In addition, the cost savings’ allocation among collaborating companies is evaluated using the cooperative game theory. Findings The results reveal validity and efficiency of the solution of the proposed model and capabilities of the cooperative game theory for reduction in gas distribution costs and improvement in the service level. Research limitations/implications This study is limited to natural gas in one region of Yazd City in Iran. Moreover, one segment of the natural gas network (i.e. distribution network) is modeled. Moreover, long-term cooperation between companies relies on fair distribution of cooperation benefits to the participants. Practical implications For the purpose of comparison and to get an insight into properties of the cost savings game, the real case study of one region of Yazd city in Iran is implemented. Originality/value This study contributes to the competitive models in the restructured gas market, particularly, in gas distribution network. The main contribution is to provide potential benefits for the participants via the horizontal cooperation.

Gas prices expose Europe’s energy vulnerability

The Cost

Significance The cost of gas-fired generation sets the electricity price in much of Europe today. Falling indigenous production has left Europe reliant on gas imports and exposed it to global liquefied natural gas (LNG) prices set by fast-recovering China. This has left retail-only electricity suppliers vulnerable and increases the risk that falling disposable incomes will undermine post-pandemic recovery. Impacts EU carbon allowance prices will stay strong. Higher energy prices will stoke inflation amid a fragile recovery, posing a dilemma for central banks. Rising gas prices have had ancillary but potentially alarming impacts as some fertiliser and CO2 producers have shut in production.

Entire Network

The concept of disaster resilience has received considerable attention in recent years and it is increasingly used as an approach for understanding the dynamics of natural disaster systems. No models are available in literature to measure the performance of natural gas network, therefore, in this paper, a new performance index measuring functionality of gas distribution network have been proposed to evaluate the resilience index of the entire network. It can be used for any type of natural or manmade hazard which might lead to the disruption of the system. The gas distribution network of the municipalities of Introdacqua and Sulmona, two small towns in the center of Italy which were affected by 2009 earthquake have been used as case study. Together the pipeline network covers an area of 136 km2, with 3 M/R stations and 16 regulation groups. The software SynerGEE has been used to simulate different scenario events. The numerical results showed that, during emergency, to ensure an acceptable delivery service, it is crucial to guarantee the functionality of the medium pressure gas distribution network. Instead to improve resilience of the entire network the best retrofit strategy is to include emergency shutoff valves along the pipes.

Purpose For libraries with limited resources, digital preservation can seem like a daunting responsibility. Forming partnerships can help build collective knowledge and maximize combined resources to achieve digital preservation goals. This paper aims to provide guidance to help libraries with limited resources achieve digital preservation goals by forming partnerships to build collective knowledge and maximize combined resources. Design/methodology/approach In 2015, librarians from four Montana institutions formed the Digital Preservation Working Group (DPWG), a collaboration to increase digital preservation efforts statewide. The group’s immediate goals were to promote digital preservation best-practices at each individual institution, and to learn about and support each other’s work. The group’s long-term goal was to implement a shared digital preservation service that would fill gaps in existing digital preservation efforts. Findings Beyond the cost savings gained by sharing a digital preservation service, the members of DPWG benefitted from shared knowledge and expertise gained during the partnership. The group also functioned as a sounding board as each institution built its digital preservation program, and it became a system of support when challenges arose. Practical/implications This paper proposes a five-point plan for creating digital preservation partnerships: cultivate a foundation of knowledge and identify a shared vision; assess the current digital preservation landscape at each institution; advocate for the value of digital preservation activities; implement shared digital preservation services; and sustain group activities and establish structures for ongoing support. Originality/value The activities of DPWG provide a model for institutions seeking to collaborate to meet digital preservation challenges. This paper shows that by implementing a structured plan, institutions can build and sustain digital preservation partnerships, thus positioning themselves to achieve digital preservation success.

Urgent Necessity

Changing environment, growing demand for gas for heating, and shut down of old gas plant, cause necessity of restructurisation of the old gas distribution network in the city. Aging distribution network, replacement of manufactured gas by natural gas and rapid growth in number of leaks cause urgent necessity of replacement and rehabilitation of the old gas pipelines. Modern materials and technologies have enabled rehabilitation gas pipelines in the narrow busy streets of the city.

PurposeIndia began gas imports since 2004 through liquified natural gas (LNG) route. Imports through trans‐country gas pipelines could help in bringing gas directly into the densely populated Northern part of India, which are far from domestic gas resources as well as coastal LNG terminals. The purpose of this paper is to report scenarios, which quantify the impacts for India of regional cooperation to materialize trans‐country pipelines. The analysis covers time period from 2005 to 2030.Design/methodology/approachThe long‐term energy system model ANSWER‐MARKAL is used for the analysis.FindingsTrans‐country pipelines could deliver direct economic benefit of US$310 billion for the period 2010‐2030. Besides these, there are positive externalities in terms of lower greenhouse gas emissions and improved local environment, and enhanced energy security. However, the benefits are sensitive to global gas prices as higher gas prices would reduce the demand for gas and also the positive externalities from using gas.Practical implicationsTrans‐country pipelines are of great importance to India as they add 0.4 per cent to gross domestic product over the period besides yielding positive environmental externalities and improved energy security.Originality/valueQuantification of benefits from trans‐country pipeline proposals till 2030.
