Oliver spoke about the challenges and opportunities associated with transitioning from WPD’s role as a Distribution Network Operator (DNO) to a Distribution System Operator (DSO).
Abstract—The article emphasized the importance and the necessity for mobile network operators to visualize infrastructure sharing as an essential phase of development in the life cycle of mobile telecommunication industry in Nigeria. With the unprecedented network infrastructure challenges characterized by unfavourable business environment and the need for quick network deployment, prompted the need for harmonizing, collaboration and consolidation by the key service providers to reduce the OPEX and CAPEX while at the same time provide quality service delivery. The idea of telecom operators to pursue the policy of doing it alone on the ground to be the first network to reach a certain subscribers base should never be entertained in the Nigerian telecom industry. Numerous benefits ranging from network availability, reliability, innovation, expansion, customer satisfaction and economic sustainability are harnessed from telecom infrastructure sharing and therefore should be enforceable by the regulatory agency to ensure collaboration by the Nigerian network providers.

Power system flexibility relates to the ability of the power system to manage changes.
Solutions providing advances in flexibility are of utmost importance for the future power system. Development and deployment of innovative technologies, communication and monitoring possibilities, as well as increased interaction and information exchange, are enablers to provide holistic flexibility solutions. Furthermore, development of new methods for market design and analysis, as well as methods and procedures related to system planning and operation, will be required to utilise available flexibility to provide most value to society.
However, flexibility is not a unified term and is lacking a commonly accepted definition.
The flexibility term is used as an umbrella covering various needs and aspects in the power system. This situation makes it highly complex to discuss flexibility in the power system and craves for differentiation to enhance clarity. In this work, the solution has been to differentiate
the flexibility term on needs, and to categorise flexibility needs in four categories.
Here, flexibility needs are considered from over-all system perspectives (stability, frequency and energy supply) and from more local perspectives (transfer capacities, voltage and power quality). With flexibility support considered for both operation and planning of the power system, it is required in a timescale from fractions of a second (e.g. stability and frequency support) to minutes and hours (e.g. thermal loadings and generation dispatch) to months and years (e.g. planning for seasonal adequacy and planning of new investments).

Evaluation of Utility Advanced Distribution Management System (ADMS) and Prot...Power System Operation
Practical and cost-effective communications solutions are needed to enable control of the growing number of integrated distributed energy resources (DERs) and grid-edge local aggregator devices such as home energy management systems. Each year, the total installed photovoltaic (PV) system capacity increases by an estimated 5 GW, over half of which is interconnected to the distribution system.1 PV’s increasing penetration—already accounting for the bulk of DER capacity—underscores the need to enable and manage its continued integration on the distribution system.2 Much previous work has shown that advanced distribution management systems (ADMS), which are effectively integration platforms for various grid control and visibility applications, can help enable the integration of higher levels of PV while also improving the overall performance and efficiency of the distribution circuit. Greater connectivity and controllability of utility- and customer-owned equipment increases the level of DER integration and overall circuit performance.3 The required performance of the enabling communications system, however, has been less thoroughly studied and is often greatly oversimplified in ADMS performance analysis. The availability of new technologies such as distributed sensors, two-way secure communications, advanced software for data management, and intelligent and autonomous controllers is driving the identification of communications standards and general requirements,4 but the link between the communications system and the expected performance of a utility-implemented control system such as an ADMS or other communications-reliant protective function requires further investigation.

ECI’s view on the Regulation on the internal market for electricity (recast)Leonardo ENERGY
The Commission’s proposals to update the directive and regulation on the internal electricity market are good steps forward in facilitating the integration of renewables. The new rules also take into account and enable the type of flexibility that is needed to balance supply and demand, with grids and storage. We do however see some areas of the proposed legislation that could go further to ensure future proofing of the market rules and not put an undue cap on the amount of renewables, flexibility or economic activity that the market could facilitate.

3 de noviembre de 2010
The IEA’s Implementing Agreement on Renewable Energy Technology Deployment (IEA-RETD) has commissioned a study on the integration of variable renewable (VRE) generation in the electricity systems (RE-INTEGRATION). The objective of the RE-INTEGRATION study is to generate new insights for key decision makers in governments and private sector regarding the following research questions:
◦What are typical sets of country specific system and regulatory factors that determine the choice of a given portfolio of flexibility options?
◦What does a – case study based – thorough assessment of the portfolios of flexibility options along the different analytical dimensions conclude on the applicability and the effectiveness of the options?
◦What general lessons might be drawn by countries with similar underlying conditions?
The RE-INTEGRATION builds on recent and on-going IEA-RETD and IEA work, in particular IEA-RETD RES-E-NEXT, IEA-RETD RE-COST 1 and IEA GIVAR III.
The study, carried out by Mott MacDonald, U.K., concludes that the continued increase of levels of penetration of VRE technologies requires new policies in order to secure a successful integration of VRE’s into markets and power systems. The study finds that there is no ‘one size fits all’ approach: policy makers will need to tailor their policy interventions to suit their country specific factors, though many VRE integration policies have the additional benefit of promoting efficient markets. Countries with weak interconnection and electrical system flexibility will face the greatest challenge, and so they will need to implement appropriate VRE integration measures at lower levels of VRE penetration.
The Volume I: Main Report outlines the overall approach taken, the background and methodology behind the study and key findings. The study undertook a more detailed analysis, through case studies, of 10 jurisdictions around the globe. The case studies included: Canada (Alberta, Ontario), Denmark, Germany, Great Britain, Ireland, Japan (Hokkaido), Spain and USA (California, Texas (ERCOT)). Detailed information relating to each jurisdiction can be found in Volume II: Case Studies.

"Understanding the Carbon Cycle: Processes, Human Impacts, and Strategies for...MMariSelvam4
The carbon cycle is a critical component of Earth's environmental system, governing the movement and transformation of carbon through various reservoirs, including the atmosphere, oceans, soil, and living organisms. This complex cycle involves several key processes such as photosynthesis, respiration, decomposition, and carbon sequestration, each contributing to the regulation of carbon levels on the planet.
Human activities, particularly fossil fuel combustion and deforestation, have significantly altered the natural carbon cycle, leading to increased atmospheric carbon dioxide concentrations and driving climate change. Understanding the intricacies of the carbon cycle is essential for assessing the impacts of these changes and developing effective mitigation strategies.
By studying the carbon cycle, scientists can identify carbon sources and sinks, measure carbon fluxes, and predict future trends. This knowledge is crucial for crafting policies aimed at reducing carbon emissions, enhancing carbon storage, and promoting sustainable practices. The carbon cycle's interplay with climate systems, ecosystems, and human activities underscores its importance in maintaining a stable and healthy planet.
In-depth exploration of the carbon cycle reveals the delicate balance required to sustain life and the urgent need to address anthropogenic influences. Through research, education, and policy, we can work towards restoring equilibrium in the carbon cycle and ensuring a sustainable future for generations to come.

UNDERSTANDING WHAT GREEN WASHING IS!.pdfJulietMogola
Many companies today use green washing to lure the public into thinking they are conserving the environment but in real sense they are doing more harm. There have been such several cases from very big companies here in Kenya and also globally. This ranges from various sectors from manufacturing and goes to consumer products. Educating people on greenwashing will enable people to make better choices based on their analysis and not on what they see on marketing sites.
