Source: [UCI](https://archive.ics.uci.edu/ml/datasets/Tamilnadu+Electricity+Board+Hourly+Readings) - 2013 Please cite: __Major changes w.r.t. version 2: ignored variable 3 in this upload as this seems to be ea perfect predictor.__ Tamilnadu Electricity Board Hourly Readings dataset. Real-time readings were collected from residential, commercial, industrial and agriculture to find the accuracy consumption in Tamil Nadu, around Thanajvur. Note: the attribute Sector was removed from original source since it was constant to all instances. Note: the attribute serviceID should be removed when predicting the target from W and VA. ### Attribute Information: 1 - ForkVA (V1) : Voltage-Ampere readings 2 - ForkW (V2) : Wattage readings 4 - Type (Class): - Bank - AutomobileIndustry - BpoIndustry - CementIndustry - Farmers1 - Farmers2 - HealthCareResources - TextileIndustry - PoultryIndustry - Residential(individual) - Residential(Apartments) - FoodIndustry - ChemicalIndustry - Handlooms - FertilizerIndustry - Hostel - Hospital - Supermarket - Theatre - University
