Chile: The world's green energy supplier by Valhalla

Thank you very much for your comments. As you mention, this is the first time seawater pumped storage will be built in Latin America with solar generation, but also the first time in the world at this scale. The only other experience of seawater pumped storage is a small 30 MW plant in Japan, which has been operating since 1999. Additionally, our aim is not only to enable a great participation of solar photovoltaics, but also other intermittent sources such as wind. Besides promoting NCRE and lowering the grids carbon footprint, the introduction of pump storage will make the grid less dependent on the fluctuation of the fossil fuel market, and ultimately more stable. As for the issues the proposal should address better, we have added information in different sections that strengthen the original proposal. In the case of the implementation risks, we addressed development, environmental, community, technological and financial risks. The first we tackle in the question “who will take these actions”, by demonstrating the ample experience of the development team. The second has to do with the location of the project that minimizes the environmental impact, described in “where will these actions be taken”. The third, related to community opposition, is discussed in “other key benefits” where we explain the profound dialogue with the local community that has led to long-term mutual gain agreements. Technological and financial risks are addressed in the proposals costs. In the section “what are the proposals costs”, we describe the investment cost of the project, and the reason it is lower than a standard pumped storage plant. Also, we explain that the economical viability of the project is given by the price it can supply energy 24/7, with out subsidies, already competitive with coal and NLG.
