In January 2014, a consortium consists of energy experts from Indonesia and the Netherlands has been collaborating in the GEOCAP project (the Netherlands-Indonesian Geothermal Capacity Building program).  Based on the activities and network we built we would like to convey a session on the electricity grid characteristic in Indonesia and renewable energy storage and the trends and development on renewable energy storage.

The energy transition and the integration of renewable energy puts challenges to the electricity infrastructure. Solar and wind energy are being generated with a fluctuating nature. Electrification of heating and mobility leads to increased electricity consumption and creates peak demand for energy on the electricity grid. This disrupts the balance of supply and demand for electricity and might overload the electricity grid. A reliable, efficient and affordable electricity supply can be realized by using “flexibility” – adjusting or shifting the demand or supply of electricity to peak-shave and balance the supply and demand for electricity becomes possible. Flexibility can come from different sources: Flexible power production, Curtailment, Demand-side management or Storage. Storage of electrical energy in battery systems is considered a promising development and the key to achieve sustainable development goals, especially SDG7.

Indonesia, being an archipelago with many islands, has different energy challenges in each island. In Java for example, the problem is on how to have more reliability and quality. While on the other islands, energy availability is still a problem. Moreover, it is a challenge to integrate the electrical networks between the small remote islands in Indonesia.

In this talk the GEOCAP community will discuss the challenges of the Indonesian electricity grid, the trends and developments of battery energy storage systems, and practical example cases of the different services that a BESS can offer.  Our target audience are renewable energy scientists, policy makers (national, province and district level) and private enterprises.
