  • Microgeneration
    Microgeneration Snapshot: Microgeneration has an important role to play in reducing carbon emissions from both domestic and commercial properties. Microgeneration technologies can contribute towards our national targets for reducing greenhouse gas emissions by 80% by 2050, as required by the ClimateHU Change (Scotland) Act 2009,UH and to targetsHU UH for electricity and heat from renewable sources as well as supporting sustainable economic growth. Growth in the use of microgeneration technology can also help alleviate fuel poverty and improve fuel security by increasing access to more affordable and locally available supplies of both electricity and heat. To date, even with the PHU ermitted Development Rights UH which apply to microgeneration technologies, there has been limited growth in the number of microgeneration installations. However, there is an onus upon planning authorities to respond to the Climate Change (Scotland) Act and Section 3F of the Town and Country Planning (Scotland) Act 1997, which requires Local Development Plan policies for emissions reduction of new buildings through the use of renewable energy technology. Scottish Planning Policy (SPP) supports investment in renewable energy projects at all scales of development, including microgeneration. Additionally, the existing Feed-In-Tariff Scheme (FIT) and the forthcoming Renewable Heat Incentive (RHI) could positively influence demand in the sector. Suggested areas of focus for planning authorities:- Give active consideration to the role of microgeneration in responding

    GENERATING YOUR OWN ENERGY HYDROPOWER A planning guide for 2D householders, communities 1 and businesses Introduction This leaflet is part of an information pack for householders, communities and businesses who want to generate their own energy through small or community scale renewable energy technologies. This may be to benefit from the Clean Energy Cashback Scheme (also known as the Feed-in Tariff) and to help tackle climate change. The pack is intended to give you some useful information on what issues you should be considering when installing a renewable energy technology, including the current planning regulations and ways in which you can install the technology to reduce any impact on you, your neighbours and the local built and natural environment. Please read Leaflet 1 Generating Your Own Energy – A Planning Guide for Householders, Communities and Businesses. This can be found at www.wales.gov.uk/planning GENERATING YOUR OWN ENERGY 1 1 A planning guide for householders, communities and businesses 2 What is hydropower? Hydropower is the use of water flowing from a higher to a lower level to drive a turbine connected to an electrical generator, with the energy generated proportional to the volume of water and vertical drop or head. What is a hydropower plant? • Small/community scale hydropower schemes can comprise of the following components: - Hydroelectric generators – placed in the watercourse - Structures – to house the hydro-turbine - Electricity transmission equipment - Pipework – to direct the water • Size - Schemes at the smaller end of this scale (typically below 100kW) are often referred to as micro hydro. The likely range is from a few hundred watts (possibly for use with batteries) for domestic schemes, to a minimum 25kW for commercial schemes.

  • Rural Electrification: GEF Experience in Renewables-Based Microgrids Ming Yang 1
    Rural Electrification: GEF Experience in Renewables-based Microgrids Ming Yang 1 Key words: Sustainable Energy for All; Actions for SDG and Paris Agreement; Case Studies. Abstract This paper discusses how the existing 1.2 billion poor people worldwide without access to electricity can be environment-friendly electrified with the implementation of the UN Sustainable Development Goal 7 (SDG7) on energy and the 2015 Paris Agreement on climate change. The objective of this paper is to demonstrate the experience of the Global Environment Facility (GEF) in rural electrification with renewable energy-based microgrids or mini-grids, and identify challenges and business opportunities in rural electrification in the least developed countries (LDCs). Several case studies are presented to show GEF’s strategies of financing renewable energy-based microgrids. This paper concludes that (1) with the demonstrated evidence of the importance of new technologies for renewable energy-based microgrids, it is necessary to improve enabling environments for creating markets conducive to the new technologies; (2) project investment is a necessary first step, but for success to be fully realized, catalyzing follow-on investments should also be set as an important goal; and (3) investments need to include effective technology transfer components for renewable energy-based microgrid technologies. 1. Introduction Ensuring all human beings to access to affordable, reliable, sustainable, and new renewable energy, Sustainable Development Goal 7 (SDG7) is one of the 17 SDGs in the 2030 Agenda for Sustainable Development adopted by world leaders at a UN Summit in 2015. In addition, signed in 2015 and effectuated in November, 2016, the Paris Agreement dealing with greenhouse gas (GHG) emission mitigation, climate adaptation and finance requires all UNFCCC Parties to put forward their best efforts through “nationally determined contributions” (NDCs) and to strengthen these efforts in the years ahead.

  • Small Hydropower Plants with Variable Speed Operation—An Optimal Operation Curve Determination
    energies Article Small Hydropower Plants with Variable Speed Operation—An Optimal Operation Curve Determination Dariusz Borkowski 1,* and Marek Majdak 2 1 Institute of Electromechanical Energy Conversion, Cracow University of Technology, 31-155 Krakow, Poland 2 Department of Energy, Cracow University of Technology, 31-155 Krakow, Poland; [email protected] * Correspondence: [email protected] Received: 2 October 2020; Accepted: 25 November 2020; Published: 26 November 2020 Abstract: In recent times, much attention has been paid to small hydropower plants (SHPs) with variable speed operation and different control techniques. Control complexity in SHPs is mainly caused by specific steady-state features of the water turbine, the long time constants of the hydraulic system and significant seasonal and/or aging-related deterioration in the system performance. This paper presents the most important features of the turbine model from a control point of view. It classifies control techniques for SHPs with variable speed operation in terms of the turbine type and SHP function (run-of-the-river and reservoir). Furthermore, various control methods are analysed taking into account the complexity of the method, dynamics, adaptability and applicability. The novelty of this study is the proposal of a simple, universal analytical formula, which, based on the basic dimensions of the turbine, determines the optimal operating curve. The proposed formula is verified on a real SHP 150 kW by comparison with measurements in the form of operational characteristics. The analysis of the annual energy production confirms the effectiveness of the approximation precision, yielding only 1% production losses, and shows an advantage of variable speed over constant speed in annual energy production of 16%.
