Wasted vs. Lost Electricity in the U.S. Electrical Grid

The Lawrence Livermore National Laboratory releases the Energy Flow Chart for the U.S. every year. The latest Energy Flow Chart is here.

As we have highlighted previously, the U.S. loses more than 67.8% of the electricity that is generated in our Grid. These losses are categorized as “Rejected Energy.” The U.S. Energy Information Administration estimates that electricity transmission and distribution losses are 6% annually

 

US Energy Information Administration FAQ “How much electricity is lost in transmission and distribution in the United States?”

which leaves nearly 62% of the losses split between Generation and Consumption with an unknown percentage occurring on either end.

“Electrical System Energy Losses” were tracked until 2002, when they were merged into the “Rejected Energy” category which includes both waste and losses. There is a distinction between these two. We are specifically referring to losses and waste in the Grid so the term “electricity” is more appropriate than energy. The Rejected category encompasses both lost and wasted electricity.

 

 

 

 

 

 

The difference:

  • Loss is non-recoverable, I2R losses that would occur in a theoretically ideal electrical network.
  • Waste is recoverable, a result of unsynchronized power and non intelligent distribution of electricity.

 

The next logical question is, “How much Waste is recoverable?”

 

It is known that electricity needs “correction” or synchronization to operate efficiently. There are various electrical distortions that naturally occur in electricity that force the Current and Voltage waveforms from their naturally sinusoidal shape (i.e. power factor, harmonics, voltage sags or swells, etc.) These distortions can be temporarily mitigated through various means of manipulation that increases the efficiency of the electricity used. Over time, newer methods and products have been introduced to the market that incrementally increase electrical efficiency.

 

This is not an exhaustive list of problems or solutions, but a general understanding of the types of products and methodologies that currently exist.

 

Electrical Distortions Converting Electricity Unbalanced Phases External Grid
  • Harmonic Filters
  • Capacitors
  • Transformers
  • Smart Meters
  • Inverter
  • Converters
  • Power Supplies
  • Rectifiers
  • Manual Load Balancing
  • Load Scheduling
  • Load Shedding
  • Transients
  • UPS Systems
  • Surge Protectors

 

The Power Quality market, which is made up by these products, is enormous and all compete to recover Waste in our Grid. These companies make billions of dollars so the opportunity is huge, but how huge?  How big is the “Wasted Electricity” market? The answer is somewhat frightening because nobody knows. We lack adequate Measurement and Verification methods to tell us precisely what is occurring in the Grid at any given moment.

 

With 3DFS Technology, we not only solve the Measurement and Verification problem, but can also solve the Wasted Electricity problem with Subcycle Correction.

 

 

In the last 7-8 years, through a detailed analysis of Waste in the grid using data we have collected, we estimate that more than 50% of the “Rejected Energy” category as depicted by the LLNL is recoverable. This means that a fully optimized Grid with zero waste would nearly double the capacity of available electricity every year.

 

Electrical Waste in live environments is typically exhibited as heat or vibration in the infrastructure, components, and wires, anywhere electricity is used. By eliminating waste in the electrical network, heat and vibrations related to waste will be eliminated leaving only non-recoverable losses in the Grid. Imagine the possibilities. Our Grid can be fully automated and use only the electricity required with full efficiency in the very near future.

    I have seen so many of the LLNL charts miss-used in countless presentations – Thank you for finally putting this into the proper context and making it clear.

    It is astonishing how ineffective energy is used and the sheer amount of waste!

    This means that a fully optimized Grid with zero waste would reduce the need of 3.78 TeraWatt Hours of electricity every year = 3.78 billion kilowatt hour = (everage price $0.12/kwt/hr) < $500 mln a year for all the country for a year. That's microscopic, the devices obviously will not pay for themselves.

      What’s up with your math? That’s $500 billion not $500.

    The grid is an extremely leaky bucket for carrying electricity. Month after month 2/3 of my bill is transmission, 1/3 is generation. In tech school they taught us that the grid is the worst thing that happened to energy in America. If the same money was spent on home based and local power development, we would be decades ahead of where we are now both by eliminating line loss and more efficient use in homes and businesses.

    From an engineering perspective, might this leave one thinking that hybrid cars (where the electricity is generate at the site of use) would be better for the environment than e-cars that get their power from the gird? (Shouldn’t this ‘loss’ factor should be considered in our public debate on this topic? Some people think going 100% electric will ‘save’ the planet from co2. But if a 2/3rds loss factor is considered, going all electric might actually make things 2x or 3x worse — even with wind mills and solar cells trying to help?) Very interesting information. Thanks!

      You’re ignoring the fact that charging EVs is schedulable and the charging systems can both balance phase loss and be remotely shed. Take a look at the virtual power plant concept Tesla deployed in southern Australia. That system concentrated on powerwalls which are fairly small storage devices. EV’s are storage systems on wheels–big ones. Generation (roof PV) and storage (powerwall or bidirectional charging) is grid-level or better reliable power at the point of use, eliminating even the unrecoverable line loss.
