Economical storage capacity at high diesel prices (> 2.5 USD/liter) and high renewable penetrations equals appr peak load (1.4 MW) Average diesel price of 2.3 USD/liter for the next 20 years (start price: 1.2 USD/liter, 6% annual growth); At 2.3 USD/liter, the LCOE of the hybrid system (3,600 kWp PV, 1,400 kW wind power, 1.4 MW battery) are around 0.51 USD/kWh, while the LCOE diesel system would be around 0.77 USD/kWh; To cover peak load, the investment into the storage system adds up to more than 5 million USD (=> 2.0 kWh storage capacity per capita).
