Prerequisites for energy use
from integrated biogas technology
The decreasing reliability of centralized power supply, rising tariffs, and problems associated with connecting to the energy grid have all contributed to the rapid development of autonomous biogas energy.
Over the past decade, the cost of electricity in Russia has risen by 450%, 50% higher than the rate of inflation. A particularly sharp jump occurred after the liberalization of the electricity market in 2011, when the cost of 1 kWh for small consumers (power up to 5-10 MW) connected to low voltage networks exceeded four roubles (nine cents). For many Russian consumers today, electricity rates are comparable or higher than in the U.S. and Eastern Europe.
Given these circumstances, agribusiness and the food industry will find it impossible to ensure their competitiveness without a strategy that involves using heating and electricity they can generate themselves.
One consequence of the price jump is a growing trend among consumers to reject the services of big energy companies, preferring to generate their own energy. In the coming years the situation is likely to become irreversible, which will further aggravate issues with centralized power and lead to even higher tariffs for those still connected to the national grid.
The savings enjoyed by forgoing connection charges to the national grid, which is important for new or expanding businesses, are another advantage of the autonomous power system. In the Moscow, Leningrad, Krasnodar and other regions, power-hungry consumers face high connection charges – as much as 100,000 roubles (2,240 euros) per kW. On average, 30% of connection applications are not granted, while delays hold up many others. In this case, autonomous energy generation frequently pays off in the investment stage.
Finally, as well as providing electricity, autonomous generation can also supply heating (cogeneration) or cooling (trigeneration), which makes it possible to achieve efficiencies of 80% or more.
