Avoided Cost Report

Follow

In this article, you will learn everything about the Avoided Cost report.

 

Introduction

The aim of this report is to calculate the avoided electric cost owing to the installation of solar PV panels in a building.

The avoided cost is understood as the difference between the electric cost without and with the solar installation.

 

Available frequencies

  • Monthly
  • On-demand (Unique)

Available Energy Sources

  • Electricity
  • Produced Electricity

Configuration

  • By Locations

Requirements

Reference Meters

To be able to generate this report it is necessary to configure the following reference meters:

  • Main Device: Representing the energy exchange between the building and the grid. As it represents both the imported and exported electricity, this device should have both Active Energy (402) and Exported Energy (452) parameters.
    • Note. If your installation cannot inject energy into the grid, it is not necessary to have parameter 452.
  • Photovoltaic: Representing the total generated energy in the installation. It should have the Exported Energy (452) parameter.
  • Machinery: Representing the total consumption of the building. It should have the Active Energy (402) parameter.

In case you don't have the devices representing all these consumptions, you can create the ones that are missing with Virtual Devices. If you would like to see an example of solar virtual devices' configuration, please visit this article.

Supplies and prices

It is necessary to assign a supply to every meter in order to calculate the avoided cost properly. This means that you need to assign supplies that refer to consumed energy and to generated energy. Learn how to assign supplies and prices.

 

Report detailing

  1. Location's name. Location's name to which the report belongs. The address is taken from Location settings.
  2. Report title and period. Report gets its title from the report configuration menu. The period is selected in the previous configuration.
  3. Energy Balance:
      • Grid Energy: Consumed energy from the grid during the selected period.
      • Generated Energy: Produced Energy by the Photovoltaic panels during the selected period.
      • Consumed Energy: Total consumed energy by the building.
      • Surplus Energy: Exported energy to the grid.
      • % coverage on consumption: Rate of consumption covered by PV generation.
      • PV Energy Self-Consumed: Rate of produced energy that has been self-consumed.
  4. Economic Balance:
      • Bill without PV: Energy cost if the solar installation was not in the building. It represents the cost of the total energy consumed by the building, considering its supply. It is divided into 2 different sections:
        • Energy Cost
        • Power Cost
      • Current bill: Current energy cost. It represents the cost of the energy that has been imported from the grid. It is divided into 4 different sections:
        • Energy Cost
        • Power Cost
        • Energy Savings: Difference between the cost without the PV installation and the cost with the PV installation
        • Energy sold to the grid
      • Savings: Economic savings obtained owing to the solar installation. It is divided into 2 different sections:
        • Energy Savings
        • Energy exported to the grid
  5. Evolution of consumption:
      • Accumulated savings so far this year
      • The energy produced so far this year
      • Evolution of Consumption graph
  6. Average day: 
      • Average daily generation: Generated energy divided by the number of days in the selected period.
      • Average daily consumption: Consumed energy divided by the number of days in the selected period.
      • Average day graph: It shows the daily average consumption and the daily average generated energy.
  7. Total Saved: Sum of the Energy Cost saved plus the profits for the Surplus Energy exported to the Grid. This value corresponds to the value in 4 - Savings.
  8. Environmental impact:
      • Avoided emissions so far this year: avoided CO2 emissions so far this year and the equivalent in trees thanks to the PV installation. It is the result of multiplying the Energy produced by the PV during the year by the conversion factor given in the previous configuration of the report.
      • Avoided emissions in the period: avoided CO2 emissions during the selected period and the equivalent in trees thanks to the PV installation. It is the result of multiplying the Energy Produced by the PV installation and the conversion factor given in the previous configuration of the report.
  9. Report footer that can be modified in the previous report settings.
