‘Definition of a Balancing Point for Electricity Transmission Contracts’ [PDF]
Electricity transmission contracts allocate scarce resources, allow hedging against locational price differences and provide information to guide investment. Liquidity is increased if all transmission contracts are defined relative to one balancing point,

Electrical Conductivities of Conductors, Semiconductors, and Their Mixtures at Elevated Temperatures
Advanced Engineering Materials, EarlyView.This article presents a comprehensive review of temperature‐dependent electrical conductivity data for multiple material classes at elevated temperatures, highlighting a persistent conductivity gap between metals and semiconductors in the range of 102$\left(10\right)^{2}$– 107$\left(10\right)^{7}$ S/m. Metal–ceramic irregular metamaterials are proposed

Comparison of Feed in Tariff, Quota and Auction Mechanisms to Support Wind Power Development [PDF]
A comparison of policy instruments employed to support onshore wind projects suggests that in terms of capacity installed, policies adopted in Germany have been more effective than those adopted in the UK.

Advanced Engineering Materials, EarlyView.Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated

'Core Indicators for Determinants and Performance of Electricity Sector in Developing Countries’ [PDF]
Since the early 1990s, substantial resources and effort have been spent on implementing market-oriented electricity reform in developing countries. Important sectoral, economic, and social dimensions are involved in electricity reform, but empirical ...

Advanced Engineering Materials, EarlyView.Carbon‐free inert anodes are essential for decarbonizing aluminum electrolysis. This study investigates a recyclate‐based MgO‐316L steel composite anode tested under galvanostatic Hall–Héroult conditions in cryolite at 1000°C. Microstructural analysis reveals selective MgO fluorination, spinel and oxide layer formation, electrolyte infiltration, and ...

A Comparison of Electricity Market Designs in Networks [PDF]
In the real world two classes of market designs are implemented to trade electricity in transmission constrained networks. Analytical results show that in two node networks integrated market designs reduce the ability of electricity generators to ...

Advanced Engineering Materials, EarlyView.The formation of nonmetallic inclusions (NMIs) was investigated in this study, carrying out immersion tests for 30 min at a temperature of 1600°C with liquid high‐silicon electrical steel (Si ≈ 3 mass‐%) and different MgO–C refractories. Conventional MgO–C refractories were considered, as well as MgO–C refractories containing MgO–C recyclate and ...

‘UK domestic energy contracts, the 28 day rule, and experience in Sweden’ [PDF]
In the UK, domestic customers must be able to terminate energy contracts at 28 days’ notice. This has been seen as a transitional protection for customers and for competition. This paper reviews the arguments for and against the 28 day rule, and examines
