Start Stabilizing Green Energy, Today

GIGA Watts is the “game changer” in large-scale sustainable energy storage. Energy storage is essential in the sustainable energy transition. Now is the time to invest in powerful, solid and large-scale battery storage: welcome to GIGA Watts.

What we are doing

GIGA Watts invests in large-scale battery storage in Europe. Investments are being made in projects for both grid stability and optimization of energy supply.

One of the consequences of the growth in the production of renewable electricity and the shutdown of coal-fired power stations is more volatility in production, with major changes in the supply of electricity from one hour to another. Storage and control of electricity is indispensable for a reliable and affordable energy system.

As a start we aim to enter the market with large-scale battery storage at wind farms and solar parks. GIGA Watts has set the goal of becoming the market leader in Europe for large-scale storage of energy. This is realized by forming strategic alliances with market parties such as service providers and energy producers.

Batteries are installed at strategic locations in the electricity grid. The GIGA Watts service partners deal with the battery capacity in the various energy markets, with the capacity market currently being the most important market. Trading on the capacity markets aims to keep the electricity grid in balance. The figure below shows schematically how this works technically.

GIGA Watts operates a virtual power plant where battery storage is mainly connected to a shell of Flexible energy assets. Also renewable assets as wind and solar are connected to the virtual power plant to realize a green power plant.

Sustainable Contributions

The projects’ CO2-savings are calculated at 28,053,000 Kg CO2 over the 15-year term per 100 MWh installed capacity. The annual CO2 savings convert into equivalents such as trees, households and return flights to New York

GIGA Watts will donate 0.5% of the annual net revenue to the GIGA Foundation.The GIGA Foundation uses these funds for two charities:
1. The protection of wild elephants;Poaching and the illegal trade in Ivory is still a threat to all elephants and has increased significantly in recent years, threatening the elephant with extinction. The number of elephants has decreased by 8% per year in recent years, mainly due to poaching (source, NRC Aug 2016). GIGA Foundation donates to organizations that are committed to the conservation of wild elephants.
2. A further to be completed project in line with the promotion of sustainable energy and energy storage in developing countries.


GIGA Watts focuses on the main Sustainable Development Goal: “sustainable and affordable energy”. In order to increase the share of renewable energy in a sustainable way, energy storage is an indispensable link. GIGA Watts invests in energy infrastructure and clean energy technology for the storage component.
