PSE – current transmission system operator – broken down by the fifth announced the tender for the so-called already. negawatts – “megawatts negative”, that is actually used. This type of solution DSR (Demand Side Response – energy demand management), increasingly popular in modern power grid management.
To put it simply – the customer offering such a service, at the request of the operator, reduces energy consumption and receives appropriate compensation, usually kilkakrotność uncollected market price of energy. This saves energy in the peaks, ie critical moments for the network, when it is most busy. Reducing the risk of failure due to DSR is worth the extra fee; PSE had estimated, eg., The power failure as a result of a blackout near Szczecin operator cost several times more than the market price.
In the latest tender PSE wants to gain the ability to reduce the on-demand power demand by 200 MW in the country. Earlier tenders gave the operator the possibility to reduce consumption by 150 MW. Under the proposed provisions, the PSE will be entitled to a maximum of 15 reduction over two years, but not more often than once a day, and up to three times a week. Contract is awarded to the person who will offer better conditions for the unused energy that is requested less.
Tender is addressed to large customers who can reduce demand by at least 10 MW. Services DSR PSE already provides such. Lignite mine in Belchatow that no major problems can stop at the request of an excavator with a capacity of several tens of MW. However, the market is already DSR service aggregators who collect clients with fewer opportunities and offer them the reduction of services in the package.
PSE repeatedly emphasized that DSR is one of the most important elements of the measures to reduce the risk of problems in the event of a decrease in the country’s available capacity below the necessary safety margin. In the next few years, such moments can happen mainly because of the need to shut down the old power units will be launched before the new ones that are still under construction.
On the other hand, the President of the Energy Regulatory Office announced a few days ago again, the third in the tender for the so-called. white certificates, or certificates of energy efficiency. According to the Law on Energy Efficiency awards certificates ERO identified projects that at least cost leads to conserve as much energy. It is all about improving the insulation of buildings, their renovation, upgrading lighting, industrial equipment, reduction of losses in district heating and electrical etc.
Winners tender white certificates granted to them will be able to sell on the market and thereby compensate for a portion of the expenditure to increase efficiency. Too ensure the effectiveness of the law, according to which all selling energy to end users and operators in the energy market must hold a certificate in having the right amount.
According to many experts, increasing energy efficiency is the best and cheapest recipe for rising energy prices and a decline in the availability of, and the system of white certificates realizes the goals well. He also pointed out that the tendering system should be more flexible, even on-line, instead of a single tender rozpisywania once a year.
