Forty-two megawatts. That’s the power of the gas turbine at the heart of the Centrale di cogenerazione di Bolgiano. This isn’t just any power plant. It’s a vital part of San Donato Milanese’s history.
The Centrale di cogenerazione di Bolgiano is more than just a building. It’s a symbol of innovation. It was built in the 1980s. It replaced three older thermal plants. The plant’s original design included two 10-megawatt gas turbines. It provided electricity and heat.
But this story is about more than just numbers. The Centrale di cogenerazione di Bolgiano is deeply woven into the fabric of this community. It fuels Metanopoli. This is a large district. The district receives heat from the plant’s extensive 52-kilometer network. This network distributes the heat produced. This provides warmth to homes and businesses.
In the early 1990s the Centrale di cogenerazione di Bolgiano expanded. Two more 10-megawatt turbines were added. This doubled its capacity. The plant underwent a complete modernization between 2012 and 2015. This modernization ensured its continued efficiency. Around thirty people operate the facility today.
The Centrale di cogenerazione di Bolgiano uses natural gas. It produces both heat and electricity. It uses a sophisticated system. This system includes a gas turbine. It also uses a recovery boiler. This boiler is for post-combustion. The plant has two marine-derived engines. These engines also provide heat recovery. There are also three traditional boilers. These support the plant’s output. Ten large storage tanks store thermal energy. These tanks hold 340 cubic meters each.
The plant’s cogeneration system is incredibly efficient. It saves primary energy. This is compared to separate electricity and heat production. This results in lower emissions. The thermal storage tanks allow for flexible production. This reduces reliance on auxiliary boilers.
Enipower aims for carbon neutrality by 2050. This is in line with Eni’s overall strategy. The plant uses advanced technologies. This reduces its environmental footprint. A new project at Bolgiano will introduce high-temperature heat pumps. These pumps will optimize heat recovery. This will use waste heat from the gas engines. They will also improve the return heat from the district heating network. This project promises even greater efficiency and reduced emissions. It could inspire other projects. This would use waste heat for industrial processes.
So here we stand before the Centrale di cogenerazione di Bolgiano. It’s a testament to ingenuity. It’s a vital resource. It’s a symbol of a sustainable future. A future powered by innovation and community.
