As the world’s demand for energy increases, it’s crucial to explore new cleantech solutions that prioritize sustainable energy and combat climate change. One of the key components of this transition involves using renewable energy sources like solar and wind power. However, as these sources are intermittent, energy storage is necessary to balance their power generation.

Energy storage, alongside smart grid technology, is the backbone of our transition to sustainable energy. By providing the ability to store and shift energy, we can reduce power generation and distribution costs, stabilize the grid, and deliver power to consumers more efficiently.

In this article, we will explore the importance of energy storage in smart grids, the services offered by companies like Intertek and Smartgrid, and how smart grid technology and energy storage will shape our energy landscape.

Why Energy Storage is Necessary for Smart Grids

The introduction of renewable energy sources like solar and wind power has made it necessary to store excess energy for use when these sources are not available. Energy storage has given us the ability to time-shift energy use, supporting peak electricity demand, and avoiding expensive charges. Furthermore, energy storage can provide support to the grid by balancing the supply and demand of electricity while stabilizing voltage and frequency to avoid power outages.

The following are some reasons why energy storage is crucial to smart grids:

  • Balancing Renewable Energy Sources: The power generation from renewable sources like solar and wind is intermittent and unpredictable. Energy storage fills the gap between the generation and demand timelines, ensuring a continuous supply of energy.

  • Energy Arbitration: Energy storage is essential in stabilizing prices by providing energy when it’s most needed, especially during peak demand times. It offers energy arbitrage that can reduce the overall cost of electricity.

  • Distribution Management: Energy storage is vital in reducing the need for the massive infrastructure required to meet peak demand. The energy stored can be distributed evenly, reducing the stress on the power grids.

  • Increasing Grid Stability: Energy storage also can stabilize the grid by balancing the supply and demand of electricity. It can help regulate the voltage and frequency of electricity to avoid power outages.

  • Improving Energy Efficiency: Energy storage is known to increase energy efficiency and reduce wastage in purchasing surplus power for peak energy usage.

Smart grids and energy storage solutions going hand in hand, providing smart energy systems that are scalable, smart, and sustainable.

The smart grid links together thousands of home and business battery storage systems and generators, as well as their national grid equivalents.

The following are some ways smart grid technology and energy storage are shaping the future of energy:

  • Greater Flexibility: Smart grid technology provides the flexibility to match the electricity supply and demand of different consumers and locations.

  • Better Energy Management: Smart grid technology enables effective energy management from generation to consumption. It can analyze data to determine peak energy consumption times and adjust energy supply to meet demands.

  • Increased Efficiency: The smart grid optimizes energy distribution, reducing energy wastage due to overproduction, reducing transmission line losses, and minimizing the costs of energy storage.

  • Distributed Energy Resources: With the smart grid, we can match demand across the distribution grid through distributed energy resources like solar panels, wind turbines, and storage units.

  • Grid Stability: The smart grid stabilizes distribution and transmission systems, reducing the chances of outages and blackouts.


Smart grid technology and energy storage are essential components of the transition to renewable energy sources and a more sustainable future. Companies like Intertek and Smartgrid provide services that enable us to store energy more efficiently, balance supply and demand, and ensure the optimal performance and safety of energy storage systems.
