SgurrEnergy authored IFC’s landmark guide, Utility Scale Solar Power Plants: A Guide for Developers and Investors. More than a decade on, its core principles — staged de-risking, an independent energy yield reported at P90, a retention- and guarantee-backed contract package, and a financial model that tells the truth — still define what makes a solar project bankable.

This paper is written to fill a void created by lack of knowledge in conducting annual operation and maintenance appraisal and its importance in PV solar power plants. Operation and Maintenance(O&M) appraisal plays a vital role in maintaining the predicted energy yield, by evaluating the existing maintenance methodologies and proposing the remedial preventive maintenance plan to increase the life span of the plant. However, it is often seen that due to budgetary constraints, lack of knowledge of performing the evaluation, annual O&M appraisal are not undertaken.

The worldwide hydrogen sector is currently experiencing a substantial shift, primarily motivated by the pressing need to eliminate carbon emissions from various businesses and mitigate the impact of greenhouse gases. Hydrogen, widely recognised as the environmentally friendly energy carrier of the future, is increasingly being acknowledged as a flexible and sustainable option. Nations globally are making significant investments in the development of hydrogen production, storage, and distribution infrastructure to fully exploit its potential. Dominantly nations have put forward the strategies to replace grey hydrogen used in refineries, fertilizer’s and steel industries by green hydrogen.

To promote transparency on Environmental, Social, and Governance risks and opportunities within the organization,SgurrEnergy believes in ensuring sustainability in its operations and project execution.Though there is no regulatory obligation to adhere to the ESG guidelines, SgurrEnergy being an ISO 9001:2015, 14001:2015 & 45001:2018 certified organization, has voluntarily decided to take initiatives to intermingle ESG reporting into its mainstream reporting procedures. Taking a step forward SgurrEnergy has developed an in-house team of Environmentalists, Sociologists, Hydrogeologists, Strategists and Climate Change Experts to help its corporate setting in strengthening its sustainability performance. This helps SgurrEnergy, cope with the ever-changing world where success is no longer limited to financial success alone but is also about future- proofing and delivering sustainable business. Sound ESG standards of the organization are seldom viewed by socially conscious investors to screen potential investments.

Wind farms/Wind Power Plants are a group of wind turbines installed in a specific geographical which has very high wind potential. The turbines are placed in such a way that it maximizes the extraction of kinetic energy from the wind and minimizes wake losses. Wind farms are often located in areas such as coastal regions, plains, and elevated/Undulated landscapes where wind speeds are higher. The main challenge faced during optimizing the design, operation, control, and grid- integration of these wind farms is the prediction of its performance due to its multi-scale flow interaction between the wind turbines and the turbulent atmospheric conditions prevailing on site.

Solar power plants have emerged as a key player in the global transition towards renewable energy sources. It is an integral part of the global shift towards renewable energy sources. These plants harness the abundant power of the sun to generate electricity, offering clean and sustainable alternatives to fossil fuel-based energy generation. However, as with any industrial infrastructure, solar power plants face various challenges, including the corrosive effects of their operating environment. The solar power plants are definitely not immune to various forms of corrosion. Corrosion can have detrimental effects on the performance and lifespan of solar power plant components, leading to increased maintenance costs and reduced energy generation efficiency. This article delves into the corrosivity concerns associated with solar power plants, explores the underlying causes, and highlights potential solutions to mitigate corrosion-related issues.

Transformer is considered as vital equipment in transmission and distribution network. Power Transformer is typically considered as the costliest equipment for any substation/switchyard project and is expected to serve lifecycle of 35years. Considering significant cost associated with power transformer and relatively long outage time in case of failure of same equipment, it is emphasizing the importance of implementing effective protection strategies to prevent or mitigate such events.

The technology however has been around for some time, with commercial production in place for over a decade. So how are the conditions different now from a few years ago? What is driving this widespread adoption of bifacial PV modules in the present time?

Aug 2022

One of the primary mechanisms adopted to ensure the same is through accurately predicting the power generation of a solar power plant through detail oriented energy yield estimations.

Wind load design of the ground-mounted photovoltaic (PV) power plants requires interpretation of the design code considering the particularities of these structures. Structural failures of utility scale PV plants are rare events, but some failures have still been observed in code-compliant structures.

In order for a solar power plant to achieve the desired generation values, it is vital that the design conceptualization translates into implementation on the ground. This means that every aspect of engineering and construction needs to be properly validated, documented, and easily accessible during the project cycle.
