    EGEB: Smart V2G extends battery life, Massachusetts pushing smarter(Tesla)grid, more


    Electrek Green Energy Brief: A daily technical, financial and political review/analysis of important green energy news.

    Baker-Polito Administration Announces Over $4.6 Million in Grants for Peak Demand Reduction Projects – The state has put money behind 9 grants aimed at reducing peak demand via, mostly, deploying energy storage intelligently. For instance – Tesla – $996,455 – Will demonstrate aggregated energy storage for peak demand reduction in National Grid territory. Tesla will work to quantify the benefits of the demonstrated peak demand reductions and evaluate the model’s viability at scale. – This reminds me of Tesla’s distributed grid work in Vermont. Look at the list of projects (it’s short). Within three to four years, Massachusetts will have the fundamental knowledge – funded and trusted by their taxpayers – to change move their energy grid well into the 21st century.

    Clean energy stored in electric vehicles to power buildingsGiven that battery degradation is dependent on calendar age, capacity throughput, temperature, state of charge, current and depth of discharge, V2G is an effective tool that can be used to optimize a battery’s conditions such that degradation is minimized. Hence, taking excess energy from an idle EV to power the grid actually keeps the battery healthier for longer – These batteries are worth too much to just sit in cars. If this research is correct, and we can use the grid to optimize batteries while the grid uses those batteries for services, then we need redo all of our equations for getting energy storage onto the grid to make use of electric car batteries also.
