As we reported in our comprehensive guide to The Renewable Energy Transition，battery storage will continue to be the enabling link between intermittent renewable generation and grid reliability with the potential to have a very significant impact on decarbonization of our energy systems.  As installation costs become more cost-efficient with strong ROIs, the light is very much shining on renewable energy storage as being the solution to our energy challenges.
 

The renewable energy resourcing challenge

The centralised power grids which power Europe’s towns and cities effectively enable modern society to function. These centralised grids rely on a continuous, uninterrupted flow of electricity, to literally ‘keep the lights on’. For decades now, this problem has been traditionally answered by burning coal, oil and natural gas in power stations, which allow for continuous power generation over a long period of time.

However, as thousands of megawatts of these traditional generation sources are retired each year, they are more and more being replaced with inherently intermittent generation from solar and wind power. The issue is that the grid needs the ability to respond to demand “as required” which simply is not possible to guarantee from sources which don’t produce energy when the wind stops blowing and the sun stops shining.

The energy transition doesn’t just mean installing solar or wind farms as the final solution.  It means re-arranging and re-designing the network infrastructure to harness the FULL potential of renewables, therefore making electricity supply cheaper, more secure and more sustainable.  As demonstrated, this means including a storage element on sites to alleviate any intermittency issues caused when solar and wind power is unavailable.

If we simply replace the previous constant generation with these intermittently generating sources such as solar and wind power, the grid will ultimately be less able to respond to surges in demand unless some form of energy storage is associated with the site to “step in” and meet the demand “as required”.

Considering that wind and solar energy are two of the most prominent forms of renewable power generation, battery storage in turn, is providing a cost effective solution to the intermittency problems associated with these renewable power sources.

Developments in battery storage technology have enabled commercially viable utility-scale sites to store the excess energy during peak production periods and release it during peak demand periods.  Afterall, there is no point in producing the energy, if we cannot make it readily accessible when it is needed.  Other than alleviating the intermittency issues that come with the introduction of renewables on a site, battery storage systems also perform many other important grid functions which we will look into in more detail in future articles.
