This document summarizes power generation and pricing in Chile for the week of March 13-19, 2017. It notes that a new 185 MW wind plant started commercial operation. Wind generation was lower than the previous week in the central region at an average plant factor of 8%. As a result, curtailments of non-conventional renewable energy (NCRE) decreased by 50%. In the southern region, wind production maintained an average plant factor of 57%. Overall, coal generation increased its participation in the energy mix to 32% while hydro generation decreased to 25%. Spot prices in the SIC area oscillated between USD 50-100/MWh for most of the week.
This week there was less hydro available in Chile's power system, requiring more generation from fossil fuels like coal, LNG, and oil. On Sunday, wind power was unusually strong in the south of the country with an average plant usage rate of 58%. Marginal costs for power generation increased across several regions this week compared to the previous week, with the highest increase at the Alto Jahuel plant rising to USD 96/MWh from USD 64/MWh.
This week saw lower renewable energy and coal availability, causing increased use of hydro, gas, and oil generation. Solar production was more unstable than the past week, with 49% curtailment on Friday. Wind production was lower in the North-Central region, with a minimum plant factor of 1% on Wednesday. Marginal costs in Alto Jahuel increased to USD 77/MWh from USD 56/MWh last week due to these factors. Electricity demand and prices dropped on Friday through the Easter holiday weekend.
This weekly report summarizes power generation and prices in Chile's SIC electricity system from February 27th to March 5th, 2017. A new 196 MW solar plant started commercial operation. Wind generation was stronger than the previous week, averaging 37% plant factor from Tuesday to Saturday. Transmission congestion in northern zones resulted in price decoupling at Punta Colorada during solar hours. Coal generation increased to 28% of the energy mix while run-of-river decreased. Spot prices remained steady from last year.
This document provides a feasibility study for the proposed Low Head Wind Farm in Tasmania. Key points include:
1) The site was chosen for its strong and consistent wind resource as well as proximity to transmission infrastructure.
2) Wind resource analysis was conducted using on-site and nearby weather station data, showing average wind speeds of 8.68 m/s suitable for wind power generation.
3) The project would involve installing 45 turbines with a total capacity of 148.5 MW, generating an estimated 590 GWh annually after losses.
4) Financial modeling under high, medium, and low electricity price scenarios showed the project would be economically viable with a medium price of $90/MWh, yielding
Decarbonizing the U.S. Energy Sector -- A Study in Optimization and TradeoffsSERC at Carleton College
The document discusses decarbonizing the US electricity sector through increasing reliance on renewable energy sources like wind and solar. It finds that increasing the geographic area considered can allow for higher penetration of wind and solar power at lower overall costs. Considering the entire US as a single system rather than separate regions allows up to 79% of electricity demand to be met by carbon-free sources like wind and solar at a cost of 8.4 cents per kWh. Aggregating resources over an even larger area, like the entire African continent, could achieve over 90% carbon-free electricity even more cost effectively. The key factor is that variability of wind and solar decreases as the area scale increases, enabling greater integration of these resources.

1) Harnessing solar energy at the multi-terawatt level in the US is possible by blending solar and wind resources from different locations to reduce variability and using existing fossil fuel and nuclear plants as backup without building new conventional plants.
2) By 2023, over 8400 terawatt hours per year of solar, wind, and other non-carbon renewable electricity could be deployed in the US, exceeding current total US electricity usage.
3) The cost of solar electricity delivered nationwide could be around 20 cents per kilowatt hour now dropping to around 12 cents per kilowatt hour by 2015, making it competitive with fossil fuels.
This document discusses opportunities in the energy sector and provides an overview of trends in energy generation, transmission and storage. It notes that electricity has become an economically stable fuel compared to oil and that energy storage can help balance intermittent renewable energy sources on the electric grid. The document also highlights the need for more resilient and distributed energy systems to support economic activity and critical infrastructure.
This document provides information on offshore wind energy from multiple sources. It discusses the historical contributors to greenhouse gas emissions from the industrial era to today. It also summarizes trends in the costs of offshore wind technology, including declining costs due to larger turbines, higher capacity factors, and moving to deeper waters and greater distances from shore. Forecasts show offshore wind growing significantly and becoming more competitive over the coming decades as technology improves.
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.
The document is a newsletter discussing wind power in Ireland. It summarizes that wind power can provide up to 50% of Ireland's energy on windy days, with a peak of 65.7%. The biggest criticism of wind power is that it requires backup capacity, but the document explains that backup is mostly obtained from already running power stations. The document also discusses how Tesla batteries could help reduce capacity charges for sites with varying power loads, and how windy weather in July helped lower Irish wholesale electricity prices that week.
This report summarizes wind data collected from two meteorological towers over a 32 month period from 2006-2009. The data was used to assess the wind resource and estimate potential energy production from a horizontal axis and vertical axis wind turbine. Key findings include:

The presenter concludes that there is significant momentum worldwide to decarbonize electricity, and that higher levels of renewable energy can be reliably achieved in Australia through emerging technologies.
The document summarizes a feasibility study conducted on developing green and renewable energies in Fremont County, Idaho. The study found that solar, geothermal, and small wind turbines are viable options for the area. Solar was identified as the most viable due to its low costs, low maintenance, and durability. Geothermal testing in Newdale showed potential, and small wind turbines could provide energy without the aesthetic concerns of larger turbines. Microhydro and natural gas require more study, while biomass and large wind were deemed not feasible.
Wind Energy in Dominican Republic ProposalCarlos Rymer
This document discusses the potential for wind energy development in the Dominican Republic. It notes that the country has an estimated wind energy potential of 24,600 GWh per year using 3% of the country's land area. Various economic scenarios are presented comparing the costs of wind energy development versus coal plant development. Under scenarios that place a tax on carbon emissions, wind energy is shown to have a cost advantage over coal. The document recommends that the Dominican government pass laws committing the country to obtaining 30% of its electricity from wind by 2020 and fund the development through a 2% tax on tourism sector transactions. This would help develop a clean energy industry and reduce electricity costs while creating many jobs.
Ceneco's electricity rates in August increased by P1.8789/kwh from July due to damage to a submarine cable connecting Cebu to other regions, which caused power imbalances. This required sourcing additional supply through the wholesale electricity market and increased costs, which were passed on to consumers. Rates decreased slightly in September by P0.1122/kwh due to reductions in generation and transmission charges. However, consumers continue to struggle with high power costs exacerbated by the economic impacts of the pandemic.
Hydropower harnesses the energy of flowing water to generate electricity. Water is diverted from a river or reservoir through a penstock to spin turbines, which turn generators to produce electricity. Advanced turbine designs aim to minimize environmental impacts like fish injury and mortality. The DOE is funding projects to develop more fish-friendly turbine concepts and test designs that use gradual pressure reduction and minimize contact with blades to reduce stress on fish passing through turbines.
Renewable energy considerations for the BahamasCharvari Watson
This document assesses the viability of solar energy as an alternative energy resource for the Bahamas. It analyzes the country's current reliance on imported fossil fuels, the electrical utility market breakdown among islands, and average household energy usage. The document finds that solar irradiance and technical potential allow for viable solar power generation. Specifically, solar parks and greenfield installations could power the out islands at 58 megawatts of capacity. This would reduce peak load on utilities and lower fuel costs. The document also examines considerations for implementing solar in more populated and urbanized areas.
This document proposes recommendations for General Motors' Fort Wayne Assembly plant to increase its use of renewable energy. It recommends:
1. Installing 14 wind turbines that are 2.5 MW and 100m tall to generate 50% of the plant's energy needs. Based on average wind speeds in the region, this setup could supply half of FWA's electricity.
2. Doubling the landfill gas capacity to achieve the target of 50% on-site power generation. Processing landfill gas into electricity would save $1.7 million annually and have a two-year return on investment.
3. Combining these recommendations could save GM money while further reducing the plant's carbon emissions and solidifying its status
The document summarizes a plan to significantly increase solar and wind energy production in the United States to stabilize and reduce carbon dioxide emissions levels. It proposes achieving this through building large solar, wind and transmission infrastructure, incentivizing electric vehicles, and implementing smart grid technologies. The plan estimates it could stop the rise in CO2 emissions and potentially reduce them by 5% per year through adding over 2000 terawatt hours of solar and wind electricity annually by 2025 at an estimated total capital cost of $2.2 trillion.
The document provides various rules of thumb and cost assumptions for energy conservation, waste minimization, and typical operating costs. It includes estimates for the costs of electricity, natural gas, labor hours, steam leaks, compressed air leaks, evaporative cooling towers, motor operation, heat loss through uninsulated pipes, insulation installation, heating and cooling, combustion efficiency, fuel switching, demand reduction, ventilation requirements, lighting costs, average disposal costs, and paint transfer efficiencies for different painting methods.

End-to-end pipeline agility - Berlin Buzzwords 2024Lars Albertsson
We describe how we achieve high change agility in data engineering by eliminating the fear of breaking downstream data pipelines through end-to-end pipeline testing, and by using schema metaprogramming to safely eliminate boilerplate involved in changes that affect whole pipelines.
A quick poll on agility in changing pipelines from end to end indicated a huge span in capabilities. For the question "How long time does it take for all downstream pipelines to be adapted to an upstream change," the median response was 6 months, but some respondents could do it in less than a day. When quantitative data engineering differences between the best and worst are measured, the span is often 100x-1000x, sometimes even more.
A long time ago, we suffered at Spotify from fear of changing pipelines due to not knowing what the impact might be downstream. We made plans for a technical solution to test pipelines end-to-end to mitigate that fear, but the effort failed for cultural reasons. We eventually solved this challenge, but in a different context. In this presentation we will describe how we test full pipelines effectively by manipulating workflow orchestration, which enables us to make changes in pipelines without fear of breaking downstream.
Making schema changes that affect many jobs also involves a lot of toil and boilerplate. Using schema-on-read mitigates some of it, but has drawbacks since it makes it more difficult to detect errors early. We will describe how we have rejected this tradeoff by applying schema metaprogramming, eliminating boilerplate but keeping the protection of static typing, thereby further improving agility to quickly modify data pipelines without fear.

Solar generation was more stable
than last week, due to less
curtailments in the North (orange
area) and North-center
(yellow area).
Wind generation in the North-
Center (yellow area) was stronger
than last week, with an average
weekly plant factor of 30% (10%
last week).
Wind curtailments increased 160%
this week (representing 15% of total
wind generation) due to strong
wind generation in the area of Pan
de Azúcar (North-Center), as
commented above.
Transmission congestions occurred
everyday during solar hours in the
Northern SIC. This resulted in
prices decoupling in Punta
Colorada. The congestion reached
Las Palmas substation on
Wednesday and have been
experienced since then due to
strong wind described above.
Weekly average marginal cost in Alto Jahuel decreased to USD 70/MWh from USD 93/MWh last week.
