Introduction
As of February 2016, microgeneration FiT rates fell to 4.4p/kWh
from 12.5p/kWh[2]. This project investigated the effects of this
change upon the financial payback for PV systems in the UK.
The nationwide roll-out of SMART meters in 2020 will
dramatically affect the export payments for future PV
installations[1]. Therefore, by calculating the actual export
versus self-consumption ratio for a property, the developed
tool will possess a higher level of accuracy.
EG-Audit supplied electricity metering data for
six case study properties that were analysed for the
development of an impartial solar assessment tool.
Rival solar assessment tools were analysed using an example property
to identify any notable variances in results and result presentation methods.
Analysis Method
Excel was used to develop the solar
assessment tool from data supplied by
the MCS and solar insolation variable
relationships from scientific publications.
Excel was used to identify electricity usage
trends from the metering data supplied by EG-
Audit for the six case studies.

This document summarizes research on wind energy forecasting in Great Britain. It finds that:
1) Wind energy generation has much larger imbalances compared to scheduled generation than conventional sources like coal and gas.
2) Errors in day-ahead wind forecasts are related to forecasted wind levels and weather conditions and contain systematic patterns over time rather than being random.
3) A time-series model using weather and wind forecasts can produce much more accurate very short-term (30 min ahead) wind forecasts compared to day-ahead forecasts, helping grid operators manage intermittent wind power.
Wind power forecasting an application of machine
The advancement in renewable energy sector being the focus of research these days, a novel neuro evolutionary technique is proposed for modeling wind power forecasters.
The work uses the robust technique of
Cartesian Genetic Programming to evolve ANN
for development of forecasting models.
These Models predicts power generation of a wind based power plant from a single hour up to a year - taking a big lead over other proposed models by reducing its MAPE to minimum values for a single day hourly prediction.
Results when compared with other models in the literature demonstrated that the proposed models are among the best estimators of wind based power generation plants proposed to date.
Wind power forecasting accuracy and uncertainty in Finland
Wind power forecasting accuracy and uncertainty in FinlandVTT Technical Research Centre of Finland Ltd
This document discusses wind power forecasting accuracy and uncertainty in Finland. It analyzes forecast errors and imbalance costs based on real data from over 20 wind power sites in Finland from 2010-2012. The key findings are:
1) Aggregating production from multiple sites can significantly reduce forecast errors and imbalance costs, lowering costs by up to 60%.
2) Combining forecasts from different weather models, such as averaging them, can improve accuracy by up to 6%.
3) Quantifying the uncertainty of forecasts through probability intervals is important as wind power penetration increases. Aggregation also decreases the variation and uncertainty of forecasts.More Reliable Wind Power Forecasting - OSIsoft Users Conference
The document discusses WINData's plan to reduce wind forecasting uncertainty using real-time meteorological observations from offsite locations. WINData will deploy remote meteorological towers equipped with sensors and a PI data acquisition system to transmit high-fidelity wind speed and direction data. This upstream wind data will help forecasters better predict ramp events and refine short-term wind power forecasts to improve grid integration and reduce operating costs for utilities. WINData has partnered with OSIsoft to develop interfaces between their remote data acquisition hardware and the PI System and ECHO platforms.
Savings Delivered by Energy Providers, IPEEC
Regulators must guide the transition of energy providers to energy services providers by benchmarking market goals, mandating participation in efficiency programs, and establishing a three-year planning process. As the market for energy efficiency emerges, regulations can use various approaches like command-and-control or market-based solutions to broaden consumer access to efficiency and deepen the savings delivered by energy providers. Definitions of energy efficiency potential from sources like the National Action Plan for Energy Efficiency provide guidance for resource planning.
Electrical wind power generation
The document discusses different electrical machines used for wind power generation. It begins with an introduction to wind power production and then describes various electrical generation schemes currently in use worldwide. These include constant speed wind turbines connected directly to the grid, variable speed turbines with a doubly-fed induction generator, and direct drive turbines with a synchronous or permanent magnet synchronous generator. The permanent magnet synchronous generator system directly connected to the grid via a full-scale power converter is highlighted as one of the most promising designs currently used due to its high efficiency and robustness.
Slides for etsap web
The document summarizes results from 288 model runs combining variations in 7 scenario dimensions for the IMRT India TIMES model, including air pollutant emissions limits, coal capacity, coal and gas prices, solar costs, and renewable and nuclear policies. It also discusses modeling variations of the upcoming EPA carbon regulation for existing US power plants, and analyzing infrastructure for transporting captured carbon for storage in the Pan-European TIMES model. Finally, it examines alternate technology scenarios for Europe's power sector and total energy system costs.
WWF study-review
WWF-Brazil published a study in 2020 called the "Sustainable Power Agenda" examining Brazil's energy production paths and challenges. In 2005, the government started prioritizing fossil fuel plants like diesel, coal and natural gas, approving 3,286 MW of capacity. This represented a 2.8% increase in Brazil's carbon dioxide emissions and 11% increase for the electric sector. As a result, WWF-Brazil concluded that choices in Brazil's electricity sector over the next 15 years would be critical for energy security, economic competitiveness and environmental sustainability.

Research poster for participation in the International School on Energy Systems, Germany.Forschungszentrum Jülich — Inst. of Energy and Climate Research, September 2017. Abstract: Electricity market reform in Ukraine coincides with
a transition to higher ecological standards and an
overhaul of the entire supply chain. Obsolete coalfired
power generation (CFPG) is playing a critical
role in supplying a maneuverable load to the
power grid and needs particularly large
investments. To quantify the economic effects of
the environmental upgrade of the CFPG, this
the paper develops a dynamic accounting-framework
a deterministic model of the sector. According to
our modeling results, full compliance of CFPG
with the EU limits regarding air pollution will lead
to a 2x decline in real electricity cost (accounting
for damage to the environment) but is not feasible
before 2026.Master\'s project presentation

It also analyzes the system's net present value, internal rate of return, investment payback period, and energy payback time. The document concludes that while upfront costs are high, solar PV could ensure cleaner energy and reduce greenhouse
Hybrid System for Electricity
The document proposes a methodology to design an efficient hybrid system for electricity production from renewable energy sources. The methodology involves calculating the required photovoltaic and wind areas to meet monthly demand, sizing the equipment based on annual averages and standard deviations, selecting standard-sized PV modules and wind turbines, and optimizing the system design by minimizing net present value costs for different PV-wind compositions.
Concepts of economic attributes part 1
This document summarizes key aspects of electricity generation and costs in the United States from the Annual Energy Outlook 2020 reference case. It finds that:
1) Natural gas and renewables increase as a share of electricity generation due to lower gas prices and declining costs of solar and wind capacity.
2) Electricity demand grows slowly at around 1% per year through 2050 due to economic growth offset by efficiency gains.
3) Natural gas combined cycle and solar PV are increasingly competitive technologies for new power plants based on their declining costs relative to revenues.
Concepts of economic attributes part 1
This document discusses renewable energy technologies and electricity generation trends in the United States. It provides the following key points:
1) In the reference case of the Annual Energy Outlook 2020, electricity generation from natural gas and renewables increases through 2050 as their costs decline, making them increasingly competitive compared to coal and nuclear power.
2) Electricity demand grows slowly at around 1% per year through 2050 due to modest economic growth and increased energy efficiency. Growth in rooftop solar also contributes to meeting demand.
3) By 2050, solar photovoltaics and onshore wind lead growth in renewable generation across regions and scenarios as their levelized costs decline over time, becoming economically competitive with other
Martin Kushler - November 17, 2011
The document discusses the benefits of pursuing energy efficiency as a utility system resource and local economic development strategy for municipal utilities. It argues that energy efficiency is much cheaper than producing new energy and provides examples where efficiency programs have saved significant amounts of energy equivalent to large power plants. The document also highlights Burlington Electric Department as an excellent municipal utility example that has achieved substantial energy savings through long-term energy efficiency investments and programs.
Two difficulties
The document discusses two difficulties for energy storage: 1) The energy storage market has not been as robust as predicted due to falling natural gas prices undermining storage applications that compete with gas generation like peak shaving and integrating renewables. 2) Operating bulk energy storage can increase emissions as it replaces clean with dirty electricity and has transmission losses. The author models a bulk storage device in various locations and finds net CO2 emissions are significant while NOx and SO2 emissions vary widely but can be large. Falling gas prices have made energy storage uneconomic for applications that compete with gas generation.
IEA Technology roadmap solar photovoltaic energy 2014
This document provides a summary and update of the International Energy Agency's 2014 technology roadmap for solar photovoltaic energy. It envisions solar PV providing up to 16% of global electricity by 2050, compared to 11% in the 2010 roadmap. Significant cost reductions have already been achieved, with further reductions possible through targeted research and development. Large-scale integration of variable solar PV will require measures to ensure grid stability and flexibility. Clear and predictable policy support is needed to continue driving down costs and overcoming non-economic barriers to deployment in order to achieve the roadmap's vision.

This document analyzes the performance of a 5 MW grid-connected solar PV power plant in India using data recorded over 2016. Key parameters like energy output, performance ratio, and final yield are calculated and compared to simulated results from PV Syst software. The plant's annual performance ratio was 73.02%, lower than the simulated 78.10% due mainly to a transformer failure. Monthly energy output and final yield varied with weather conditions. While most months matched simulated results within 9%, August differed by 21%. The analysis provides insights to improve plant maintenance and optimize performance.

How New Jersey’s Energy Master Plan (EMP) is critical to creating a more sust...American Sustainable Business Council
Governor Murphy, through Executive Order 28, has set New Jersey on the path toward transitioning to 100% clean energy by 2050.
In June, the Board of Public Utilities (BPU) issued a draft of an updated Energy Master Plan (EMP) that encompasses a dramatically broader scope than previous EMPs, and features a series of seven strategies that will guide the state to address the imminent threat of climate change and to reach Governor Murphy’s 100 percent clean energy goal.
This timely webinar features experts who will provide an overview of the EMP draft, and how it has the potential to result in significant economic benefits, including the creation of new jobs, industries and workforce development opportunities for the state’s residents and business community.
The NJ BPU is accepting comments on the EMP draft until September 16th. Please join us so that you can add your voice with others in the sustainable business community to help make the EMP a strong and effective roadmap to creating a clean energy economy. Wind_resource_assessment_using_the_WAsP_software_DTU_Wind_Energy_E_0174_.pdf
This document provides an introduction to wind resource assessment using the WAsP software. It describes how wind resource assessment is used to estimate the wind resource potential at a site based on meteorological measurements and numerical modelling. The WAsP software implements a wind atlas methodology using measured wind data to generate a generalised wind climate, which can then be applied to a site to produce a predicted wind climate and estimate annual energy production considering wake losses from the wind farm layout. Validation, uncertainties and site conditions are also discussed.
Cost and Benefit Analysis of Solar Panels at Home
Due to the high utility costs in Cabanatuan City, the solar panel system is rapidly approaching. People in the middle and lower income classes of the country particularly feel the effects of inflation. In order to address the ongoing rise in oil prices and pollution, the government has made the development of renewable energy one of its top priorities. In order to help consumers reduce their utility costs, save money, and produce greener energy, a study on the installation of a solar panel system at home was carried out. The researchers gathered some data from consumers to be utilized as the basis for the contractors' computations, where the adoption of a 3kw on-grid solar panel system was recommended to those respondents with power bills under ₱2,400. The project costs approximately ₱150,000 in total, including installation and permits, and can save approximately ₱2,300 monthly. This investment has a 5.4-year payback period and a total savings of ₱402,000 over a 20-year period. The consumption analysis revealed a sensitive effect on savings and investment payback periods. The study proved that the project's long-term savings can be more than double the initial investment. A SWOT analysis was also performed to highlight the advantages and disadvantages of having an on-grid solar panel, as well as the benefits of clean energy and gas reduction in our environment that future generations could benefit from. The project's cost-benefit is a win-win investment for everyone who wants to save money while also enjoying cleaner air in the long run.
Integrating Renewable Energy into the Electricity Grid
A number of factors are contributing to increases in renewable energy production in the United
States (and beyond). These factors include rapidly declining costs of electricity produced from
renewable energy sources, regulatory and policy obligations and incentives, and moves to reduce
pollution from fossil fuel-based power generation, including greenhouse gas emissions. While
not all renewable energy sources are variable, two such technologies – wind and solar PV –
currently dominate the growth of renewable electricity production. The production from wind
and solar PV tries to capture the freely available but varying amount of wind and solar
irradiance. As the share of electricity produced from variable renewable resources grows, so does
the need to integrate these resources in a cost-effective manner, i.e., to ensure that total
electricity production from all sources including variable renewable generation equals electricity
demand in real time. Also, a future electric system characterized by a rising share of renewable
energy will likely require concurrent changes to the existing transmission and distribution
(T&D) infrastructure. While this report does not delve into that topic, utilities, grid operators
and regulators must carefully plan for needed future investments in T&D, given the lead times
and complexities involved.

- 1. Development of a Solar PV Energy Assessment Tool for EG-Audit Ltd. Chemical & Biological Engineering. Student Name: Daniel Owen References Supervisor Names: 2016 Dr Alan Dunbar & Kevin Aylward 0 4000 8000 12000 16000 20000 LifetimeProfit(£) ● Primary solar solution providers ● Secondary solar solution providers ● Not-for-profit organisations Introduction As of February 2016, microgeneration FiT rates fell to 4.4p/kWh from 12.5p/kWh[2]. This project investigated the effects of this change upon the financial payback for PV systems in the UK. The nationwide roll-out of SMART meters in 2020 will dramatically affect the export payments for future PV installations[1]. Therefore, by calculating the actual export versus self-consumption ratio for a property, the developed tool will possess a higher level of accuracy. EG-Audit supplied electricity metering data for six case study properties that were analysed for the development of an impartial solar assessment tool. Rival solar assessment tools were analysed using an example property to identify any notable variances in results and result presentation methods. Analysis Method Excel was used to develop the solar assessment tool from data supplied by the MCS and solar insolation variable relationships from scientific publications. Excel was used to identify electricity usage trends from the metering data supplied by EG- Audit for the six case studies. [1] Gans, W. et al.

Research the potential of reducing the reliance of the tool upon the MSC supplied insolation data; instead, utilising observed relationships between solar insolation levels and the variable factors. Conclusions Average UK payback period for PV systems will increase by 32.5% under new legislation (using 2015 efficiencies). Inputs and results overlooked by the rival calculators, but included in EG-Audit’s assessment tool, are listed below; On average, the summer months accounted for 53.8% of total annual export for the properties analysed.
