In view of the inadequate implementation of the grid operation and maintenance standards and specifications current, the lack of planning in cost usage, and the inability to achieve single equipment collection of costs, taking 220kV substation as an example, this paper proposes a single asset operation and maintenance cost calculation method based on grid standard operations, and puts forward suggestions on the cost management of grid equipment operation and maintenance. Through verification and analysis with the relevant provisions of the cost supervision and examination method, the power grid company will face greater operating pressure, and the cost management level needs to be further improved. Through the calculation of the operation and maintenance cost of a single asset, it provides a reference basis for the distribution of the operation and maintenance cost of the power grid enterprise, and at the same time provides a reasonable explanation for the power grid enterprise to adapt to the cost supervision and review of the transportation dispatching pricing.

The large scale composting activity needs mechanical equipments foroperational efficiency like The Cakung Slaughterhouse has been done.Installation of mechanical equipments and buildings make it costly compare tomanual composting activities. The cost of mechanical composting need to becounted such as investment, operation and maintenance cost in order to getthe specific cost of compost production. This can be used for pricing compostproduct. According to the analysis, the best pricing for compost product is morethan Rp. 807/kg, for example Rp. 1000/kg compost. It means that CakungSlaughterhouse need increase gradually the existing compost price from Rp.500/kg to Rp. 1000/kg compost. It need for guarantying for sustainable compostproduction.Key Words: Slaughterhouse, mechanical compost, specific cost

Mass Rapid Transit

Mass rapid transit (MRT) is an efficient transportation mode that is urgently needed by a growing city such as Jakarta, Indonesia. However, limited research has attempted to evaluate the system’s current performance through a comprehensive, unit-based calculation of the costs of MRT operation and maintenance. This research aimed to develop a system for calculating and comparing MRT operation and maintenance costs per kilometer per year. The cost model has three components, namely, capital, operation cost, and maintenance cost, which are, respectively, calculated based on their percentage toward total cost. The cost model calculation determined that Jakarta MRT operation and maintenance costs total USD 8.44 million per kilometer per year. This result was compared to other countries’ MRT operations.

The current complex internal and external situation puts forward higher requirements for the precise investment of funds for power grid companies. This paper proposes a two-stage operation and maintenance cost input optimization allocation technology based on comprehensive evaluation and Gini coefficient adjustment. This technology firstly identifies the influencing factors of operation and maintenance cost input, and combines the result of factor identification to construct an evaluation index system based on asset status and scale attributes. Through comprehensive evaluation and collection of index-related data, it determines the initial distribution coefficients and initial distribution coefficients of related enterprises based on the entropy weight method. Then combined with the principle of Gini coefficient, optimize the initial allocation plan to obtain the final investment allocation quota. This paper conducts empirical analysis with 10 companies as the research object, and the results show that the model can provide theoretical support and method reference for reasonable investment and reasonable decision-making of operation and maintenance costs of power grid companies under the requirements of precise investment management and control.

This paper analyzes a novel, cost-effective planar waveguide solar concentrator design that is inspired by cellular hexagonal structures in nature with the benefits of facile installation and low operation and maintenance cost. A coupled thermal and optical analysis of solar irradiation through an ideal hexagonal waveguide concentrator integrated with a linear receiver is presented, along with a cost analysis methodology, to establish the upper limit of performance. The techno-economic model, coupled with numerical optimization, is used to determine designs that maximized power density and minimized the cost of heat in the temperature range of 100–250 °C, which constitutes more than half of the industrial process heat demand. Depending on the incident solar irradiation and the application temperature, the cost of heat for the optimal design configuration ranged between 0.1–0.27 $/W and 0.075–0.18 $/W for waveguide made of ZK7 glass and polycarbonate, respectively. A techno-economic analysis showed the potential of the technology to achieve cost as low as 80 $/m2 and 61 $/m2 for waveguide made of ZK7 glass and polycarbonate material, respectively, which is less than half the cost of state-of-the-art parabolic trough concentrators. Overall, the hexagonal waveguide solar concentrator technology shows immense potential for decarbonizing the industrial process heat and thermal desalination sectors.

This work aims to consider the combination of different technologies regarding energy production and management with four possible configurations. We present an energy management algorithm to detect the best design and the best configuration from the combination of different sources. This combination allows us to produce the necessary electrical energy for supplying habitation without interruption. A comparative study is conducted among the different combinations on the basis of the cost of energy, diesel consumption, diesel price, capital cost, replacement cost, operation, and maintenance cost and greenhouse gas emission. Sensitivity analysis is also performed.

Compared with the traditional power grid, UHV power grid has the character of stronger system function, higher control requirement, and also set a higher request to the daily maintenance management. The operation and maintenance experience of Shan-xi province electric power company on the UHV power grid proved the importance of establishing the new mode of management, strengthening the application of automation technology, and guarenteeing the technology and resources . In order to improve the efficience and quality of UHV power grid operation and maintenance, we should speed up the formulation of operation guidelines for UHV live working and strengthen personnel training and reserve technical talents.
