Bulgarian Plant Invests in
Cogeneration
The heating utility of the Bulgarian
capital of Sofia has started construction of
a 32 million lev ($21.3 million) cogenera-
tion installation at the Sofia Thermal Power
Plant. The utility, Toplofikatsia Sofia, said
the new unit will have a 40 MW installed
capacity for electricity and an 80 MW heat-
ing capacity. Cogeneration will boost the
efficiency of the Sofia Thermal Power Plant
by enabling it to produce 5 percent more
energy with 10 percent less fuel. Launch of
the cogeneration installation is expected to
reduce the plant’s natural gas consumption
by more than 10 million cu m (353.2 million
cu ft) per year, while slashing emissions by
almost 20,000 tons of carbon dioxide equiv-
alent. The project, planned to be operational
in 2014, will be built by a consortium of Risk
Engineering and Silovi Machini.
Study: Potential for CHP in
Wastewater Treatment Plants
The U.S. Environmental Protection
Agency Combined Heat and Power
Partnership recently published a study titled
Opportunities for Combined Heat and
Power at Wastewater Treatment Facilities:
Market Analysis and Lessons from the
Field. This market and technical analysis
found that CHP is a strong technical fit for
many wastewater treatment plants – and a
compelling investment, depending on local
electricity prices. While many plants have
already adopted CHP, substantial oppor-
tunities remain. The study can be down-
loaded at http://tinyurl.com/7f2a9hc.
