Why solar power?

  • In the United States, the North East and West Coast regions have the highest average electricity rates ( >US 15¢/kWh).
  • Average price of residential solar electricity is cut with grants of approximately 30%.
  • Electricity demand is growing, especially with electric vehicles soaring.
  • Reduction of greenhouse-gas emissionsfrom traditional fossil fuels power plants.

Where electricity prices rise, the solar industry grows!

Why residential batteries?

  • Over 24 hours, global grid consumption varies to reach a peak on evenings.
  • During the afternoon, the additional solar power on the grid, year after year, contributes to increasing power generation.
  • However, this generations falls to zero at the end of the day as the consumption rises.
  • The current solution is to start peak power plants for a short period of time which is  very costly for utilities.
  • DER can attenuate the ramp using residential energy storage.

Why reactive power?

Electricity transportation and distribution problems such as voltage conservation, reactive power and harmonic losses cost millions to utilities in mitigation equipment and power losses.

  • Voltage kept at low level represents 3% in energy savings.
  • Refrigerators and air conditioners impose loads that exceed the amount of power they actually use.
  • Nonlinear loads (electronic power supplies) impose harmonics, causing additional energy losses.

What is a smart grid?

Smart grids emerge out of the computerization of energy devices, allowing for the optimization of generation, consumption and exchange with thanks to modern communication technology such as Ethernet. Among other things, they allow the following:

  • Generate, consume/sell solar power efficiently.
  • Be energy-independent.
  • Store energy into home batteries for peak hours and optimize Time of Use.
  • Cut distribution losses and monetize them.
  • Provide grid services through inverters (voltage control, reactive power injection, active harmonic filtering).
  • Use upcoming smart-grid requirements (California Rule 21, IEEE2030.5, OpenADR, etc.).

Idenergy’s system is able to encompass all revenue streams by simultaneously addressing the three aforementioned issues.
