EIA: natural gas-fired reciprocating engines are being deployed more to balance renewables

Green Car Congress

Before 2010, reciprocating engines typically had no more than 9 MW in capacity, but in recent years, larger units that range from 16 MW to 19 MW have been installed throughout the United States. Several of these engines are typically installed at one generation facility. MW of capacity.

This Dutch City Is Road-Testing Vehicle-to-Grid Tech

Cars That Think

Unlike those you may have grown accustomed to seeing, many of these stations don’t just charge electric cars—they can also send power from vehicle batteries to the local utility grid for use by homes and businesses. Debates over the feasibility and value of such vehicle-to-grid technology go back decades. This is good for the grid.

To Store or Not to Store: That is the Question

Green Car Congress

Typical daily grid demand. “ Why do you need energy storage on the grid, when the grid is full of power plants that generate all the energy that is needed? ” It would seem like a good question to ask and applies the same logic has been used for the past fifty years in determining grid strategy.
