Amazon EC2 Spot Price History: 2014--2015, 2017--2023
<p>Spot price history for Amazon EC2 instances for various regions collected from 2014 to 2015, and 2017 to 2023.</p>
Conjunto de dados Modelo de Regressão Aplicado à Previsão de Preços SPOT de Energia Elétrica (Dataset Regression Model Applied to Electric Energy SPOT Price Forecasting)
<p>Esse conjunto de dados utilizou DataSets de duas fontes distintas: CCEE e ONS. Como são órgãos públicos os dados são acurados, transparentes, confiáveis e de boa qualidade. Os dados de entrada possuem as variáveis que são utilizadas no modelo atual do PLD, já citado. São elas: as datas, o armazenamento de água, a ENA, a expectativa de ENA para a próxima semana e a carga.</p> <p>As datas são dados diários entre janeiro de 2013 e janeiro de 2017. O armazenamento de água é dado por submercado e apresentado em porcentagem da capacidade máxima. A ENA e a expectativa dela para a semana seguinte são apresentadas em porcentagem a partir das chuvas realizadas convertidas em MWmédio pelas previsões feitas utilizando dados históricos (1932-2007). A carga está em MWmédio. E o PLD em R$/MWh.</p> <p>Os soma dos dados dos quatro submercados (SE/CO, SU, NE, NO) de cada dado nos fornece a informação do Sistema Nacional Interligado (SIN).</p> <p>As variáveis de carga, armazenamento e ENA foram retiradas do histórico de operações do site da ONS, disponibilizados para download em ‘csv’. E o PLD do site da CCEE, disponibilizados em ‘xls’.</p> <p>Foram mesclados a partir das datas formando o arquivo de entrada para o modelo utilizado nos experimento</p> <p> </p> <p>Metadados / Metadata</p> <p>Storage of water: percentage of storage of water by submarket.<br> ENA and expectative of ENA: presented by percentage of previsions of rains that happen converted on MWmedium by previsions did with a historic (1932-2007). Data are by submarket.<br> Charge: charge by submarket give on MWmedium.<br> PLD: give on R$/MWh<br> The sum of each variable is the data of the total system.</p> <p> </p> <p> </p>
AWS Spot Price History
<h1>AWS Spot Price History</h1> <p>This dataset tracks historical prices for AWS spot prices across all regions. It is updated automatically on the 1st of each month to contain data from the previous month.</p> <h1>Data format</h1> <p>Each month of data is stored as a ZStandard-compressed <code>.tsv.zst</code> file.</p> <p>The data format matches that returned by AWS's <code>describe-spot-instance-prices</code>, with the exception that availability zones have been replaced by their global ID. For instance, here are some example lines from one capture:</p> <p><code>euc1-az2 i4i.8xlarge Linux/UNIX 1.231800 2023-02-28T23:59:57+00:00</code><br><code>euc1-az3 r5b.8xlarge Red Hat Enterprise Linux 0.749600 2023-02-28T23:59:58+00:00</code><br><code>euc1-az3 r5b.8xlarge SUSE Linux 0.744600 2023-02-28T23:59:58+00:00</code><br><code>euc1-az3 r5b.8xlarge Linux/UNIX 0.619600 2023-02-28T23:59:58+00:00</code><br><code>euc1-az3 m5n.4xlarge Red Hat Enterprise Linux 0.476000 2023-02-28T23:59:59+00:00</code><br><code>euc1-az2 m5n.4xlarge Red Hat Enterprise Linux 0.492000 2023-02-28T23:59:59+00:00</code><br><code>euc1-az3 m5n.4xlarge SUSE Linux 0.471000 2023-02-28T23:59:59+00:00</code><br><code>euc1-az2 m5n.4xlarge SUSE Linux 0.487000 2023-02-28T23:59:59+00:00</code><br><code>euc1-az3 m5n.4xlarge Linux/UNIX 0.346000 2023-02-28T23:59:59+00:00</code><br><code>euc1-az2 m5n.4xlarge Linux/UNIX 0.362000 2023-02-28T23:59:59+00:00</code></p> <p>When fetching spot instance pricing from AWS, results contain some prices from the previous month so that the price is known at the start of the month. These prices are adjusted in this dataset to be at the exact start of the month UTC:</p> <p><code>euw3-az2 g4dn.4xlarge Linux/UNIX 0.558600 2023-01-01T00:00:00+00:00</code></p> <p>For data from 2023-01 and before, this data was fetched more than one month at a time. This should have no negative impact unless, for example, an instance type was retired before the month began (and there should therefore be no price). These older files also only contain default regions. Data from 2023-02 and later contains all regions, including opt-in regions.</p> <h1>Using data</h1> <p>You can process each month individually. If you need the entire data stream at once, you can cat all files to <code>zst</code> together:</p> <p><code>cat prices/*/*.tsv.zst | zstd -d</code></p>
Amazon Spot Service Price History (2018-2022.05)
<p>The price history of Amazon's spot services. Amazon only allows to download the most recent 2-month or 3-month data, so the data are saved in separated files with overlaps.</p>
Peru's Spot Price of Electricity in Hourly Basis, 2005 - 2023
<p>Peru's spot price of electricity in local currency (S/) by kWh.</p>
