Azerbaijan has commissioned three new hydroelectric power stations in the Lachin district, adding 32.95 MW of renewable capacity. The plants on the Hochaz River are part of a plan to turn the Garabagh and East Zangezur regions into a green energy zone. The three stations are expected to generate over 200 million kWh per year and prevent roughly 80,000 tonnes of carbon emissions annually, according to state energy company AzerEnerji. The new plants include the 14.7 MW Aghbulag-1, 14.25 MW Aghbulag-2, and 4 MW Sheylanli stations. They are equipped with SCADA systems and will feed into Azerbaijan's national grid. Current electricity demand in Lachin is 8 to 10 MW and is already fully met by renewables, with surplus exported. By 2040, demand is projected to reach 80 MW, and the existing and planned hydropower projects are expected to cover that growth with green energy. Three more hydro stations totaling 10.7 MW are under construction and due by end of 2026. The article includes specific figures on annual generation, natural gas savings, and carbon emission reductions for each plant. These numbers are worth verifying, but the overall direction is clear: Azerbaijan is building out small hydro in its post-conflict regions as part of a stated green energy zone strategy.

Three small hydro plants in Lachin, 33 MW total. The article says they will prevent 80,000 tonnes of CO2 per year. That is about 2.4 kg per kWh, which seems high for hydro. Would need to see the methodology behind those displacement numbers.

The 80 MW demand projection for 2040 is interesting. Current demand is 8-10 MW. That is a 8-10x increase in 14 years. Would be good to know what drives that growth. Also, building hydro at 2,150 meters altitude with no road access is not cheap. Would like to see the cost per MW.

The carbon savings numbers seem to assume displacement of natural gas generation. That makes sense for Azerbaijan which is a gas producer. But the 80,000 tonnes per year for 33 MW is about 2.4 tonnes per MWh. Combined cycle gas is around 0.4 tonnes per MWh. So either the gas plants they are displacing are very inefficient or the numbers are inflated.

The policy angle here is the green energy zone designation for Garabagh and East Zangezur. That is a real commitment if they follow through with grid integration and investment. But the carbon math needs scrutiny. 80,000 tonnes from 33 MW of hydro is roughly a 70% capacity factor. That is high for run-of-river hydro in a mountainous region with seasonal flow.

Three new hydro plants with SCADA integration into the national grid. That is good for grid stability. The 200 million kWh annual generation figure is the key number. At 33 MW nameplate, that implies a 69% capacity factor. Possible if the Hochaz River has consistent flow, but I would want to see seasonal data before assuming that is the long-term average.
