The power of residential battery energy storage systems

The importance of applying significant focus on the actual implementation of energy storage as part of smart energy transition solutions.

A relevant quote from the report produced by SolarPower Europe ‘European Market Outlook For Residential Battery Storage 2020–2024’: “Last year, 745 MWh from 96,000 systems were installed, representing a 57% annual growth rate. The foundation for the European residential BESS sector was laid by a handful of countries, where a large residential solar market already, exists – namely Germany, Italy, UK, Austria, and Switzerland. These Top 5 markets absorbed over 90% of all BESS installations in 2019 and are also responsible for a similar level of the nearly 2 GWh of operating residential storage capacity in Europe so far.”. (Note: BESS stands for Battery Energy Storage Systems).

The abovementioned report fully supports the developments and implementation success experienced elsewhere, by for example iwell; please refer to their website.

Another good example worth exploring, is the independent Dutch solar platform Zonatlas NL, freely accessible for individual households and individual business (e.g. SME). Zonatlas has for several regions in the Netherlands an on-line battery storage option available in case an individual household wants to make a connection with the energy generated by solar panels – please refer to the following website for more information:


The author of this blog as well as the Dutch companies EnShared and Zonatlas made a contribution to the Position paper ‘Virtual Energy Plants through Energy Commons’, which was recently issued by the independent foundation Future Energy Systems – please refer to: Energy storage prominently features in this Paper, as it is an essential component in creating virtual energy plants. And when, for example, sufficient storage capacity is connected to the micro-grid, self-balancing and the trading of stored electricity can also be exploited. These storage systems provide another important form of flexibility to the market and will gain greater public interest as the share of renewables increases.


IEA World Energy Outlook 2020 clearly states: “Solar becomes the new king of electricity…..”. This makes the role of storage more important for affordable and reliable energy systems in the near future.

For further information, please click here, but the following quotes from IEA’s WEO 2020 are worth mentioning here:

  • “Renewables grow rapidly in all our scenarios, with solar at the centre of this new constellation of electricity generation technologies. Supportive policies and maturing technologies are enabling very cheap access to capital in leading markets. With sharp cost reductions over the past decade, solar PV is consistently cheaper than new coal- or gas fired power plants in most countries, and solar projects now offer some of the lowest cost electricity ever seen.”.
  • “Storage plays an increasingly vital role in ensuring the flexible operation of power systems, with India becoming the largest market for utility-scale battery storage.”.


In the Netherlands many realise that the current and past tax and subsidy regime hasn’t really supported the large scale implementation of energy storage to date. Nevertheless, we observe good examples of implementation in for example apartment buildings where a smart battery system significantly lowers the peaks in the power supply resulting from the elevator usages.

It’ll be obvious that in the Netherlands we should focus more and more on the smart introduction of battery and energy storage systems.

We will continue to write about future developments.


Note (re.

A Virtual Energy Plant through an Energy Common is a network of local small- and medium scale power and heat generating units such as wind farms, solar parks, and Combined Heat and Power (CHP) units, as well as flexible energy consumers and storage systems. The interconnected units are dispatched through an automated central ‘control room’ of the Energy Common thereby remaining independent in their operation and ownership. The objective of a community based Virtual Power Plant is twofold. First, it needs to generate enough renewable energy for the local community. Secondly it should relieve the load on the electricity grid by smartly distributing the power generated by the individual units during periods of peak load. In case of a surplus, the combined power generation and power consumption of the networked units in the Virtual Energy Plant can be traded on the energy exchange.
