PSEG Energy Usage data notes

[symington]

Electricity Data & Gas Data
​- Industrial category is not "true" industrial and can be considered Commercial

• Classification of Industrial is based on SIC code
• includes Princeton University property in the Commercial category
• kWh & Therms are billing information and not actual usage – In the vast majority of cases they are one and the same but they will be instances either because of an estimated bill or a corrected bill where they can be different. This explains negative values in kWh & Therms.
• PSEG can provide data in excel on a Quarterly basis
• No limitations on use of data as it is in aggregate
• Meter to resident or commercial is roughly 1:1
• Data needs to be weather normalized using heating and cooling degree data for the area
• Princeton Hospital closed and moved to Plainsboro on May 23rd 2012 so likely explains drop in Borough Commercial usage
• Princeton Township and Borough consolidated into the Princeton Municipality on January 1st, 2013 but PSEG still records usage separately
• PSEG maintains some streetlights in Princeton but not all. It needs to be determined if the streetlight data is only PSEG owned & maintained. The remaining streetlights are owned and maintained by the Municipality and included in their bill

Ideas for energy usage data

• weather normalize data to determine if usage is increasing or decreasing on factors other than weather

• determine the Greenhouse Gas emissions resulting from the usage data using PSEG energy source data or other proxy
• Create a tool that will show how energy efficiency or conservation measures in Princeton could impact the overall consumption in terms of easier to understand equivalencies http://www.epa.gov/cleanenergy/energy-resources/calculator.html

Hi, I would move this to the ptonEnergy project, so people working on it like slacker and rakesh see the notes. Also, permanent information such as notes on the data are better placed in README.md than in an issue: issues get resolved and are then mostly hidden.

Added this to ptonEnegry project.
More details to follow after @symington meeting with PSEG today.
