Rwanda pumped storage power station bidding

Does Rwanda’s development path meet the forecasted electricity demand?

The results within this report indicate that the forecasted electricity demand is still met by the least-cost optimal development path. This is expected to propel the country’s economic growth, both in terms of providing support for the emerging industry sector and improving the standard of living for Rwanda’s citizens.

What is the geothermal resource potential of Rwanda?

The geothermal resource potential of Rwanda is estimated to be 120 MWe (+/- 50MWe). A reasonable initial target for geothermal power generation was considered/recommended as 50 MWe. MININFRA conducted evaluations of the geothermal resource, including geophysical, geochemical, and hydrogeological surveys. The conclusion

Which hydroelectric pumped storage plant is developing a new generation?

Lippold F, Hellstern N. Hongrin–Léman hydroelectric pumped storage plant, Veytaux II powerhouse – developing a new generation of multistage storage pumps. In: Proceedings of 2012 HYDRO conference. Fayolle D, Lafon S. Variable speed applied to hydroelectric schemes.

Can a scenario approach be used to calculate wind power bids?

A similar approach to was proposed in to calculate the power bids of a wind farm and a set of cascaded hydropower plants, without pumped-storage, for the day-ahead electricity market. As in , the uncertainty associated to wind power and hourly energy prices is considered via a scenario approach.

Can a pumped storage hydropower system use both pumps and turbines?

Since the pumped storage hydropower system comprises two different pipes (one for pumping water flow and the other one for water discharged flow), the scheduling model considers the possibility of simultaneously using both pumps and turbines.

What are the operation modes of pumped-storage units?

In the MILP formulation, each operation mode of the pumped-storage units (generating, idle and pumping) is modeled as a pseudo-unit, as referred to by the authors. Transition costs among different operation modes as well as minimum on/off times for each mode are considered in the paper.
