How does LENZ work?

• Using the graphical user interface, users select project data files:
  • consumer billing records
  • daily weather
  • normal weather
• Applying various degree days with linear regression modeling, LENZ selects the best weather model for each premise and estimates weather normalized annual usage.
• LENZ delivers powerful graphical analysis in an easy-to-use fashion.

Why LENZ?

• Easily determine energy usage for a normal weather year.
• Weather-normalized annual usage is critically important for:
  • understanding customer usage by class and other segmentation strategies
  • evaluation of energy efficiency programs
  • customer-specific reporting
  • long-term system planning

Features Include:

• Automatic matching of daily weather to periodic billing data at the premise level.
• Unlimited number of premises in analysis.
• Heating and cooling degree day models.
• Automatic selection of best degree day base for each premise in analysis.
• Informative reports and graphics.
• Ships with historical and normal temperature data for all stations in the state of your choice.
• Model diagnostic information for advanced users.
• Export results to Excel or database.
• Built on the powerful analytical and reporting capabilities of SAS® software.
• Available for desktop, server or mainframe installations.

Frequently Asked Questions:

• What are the LENZ models?

The LENZ models relate energy usage for a customer or customer class (i.e. resedential) to user selected weather data. The weather data are not only specific to the utility but can also vary to reflect weather zones within a utility service territory. LENZ allows the user to define the weather station for each customer. This becomes important when significant weather variances exist within the service territory.
