29 ADDITIONAL SYSTEMS

Additional power transmission systems are made up of power transmission facili- ties essentially and mainly designed to supply electrical energy to users that are not subject to price regulation (i.e. large industries, mining, etc.) and of facilities designed to allow power companies to inject production into the electrical system. Power transmission by means of these systems is regulated by private contracts between parties.

The additional systems market is not without extensive environmental and concession processes currently faced by power transmission projects. It has been observed that estimated deadlines greatly differ from real conditions.

Even so, Transelec has confirmed its interest in developing the additional power transmission market and establishing the company as a strategic partner for the execution of energy development required by the market. This was understood by Metro S.A., which signed an agreement with the company in order to develop a power transmission system to meet our

39 By means of this Quality Management System certification, Transelec commits to continuously improve power supply safety by means of proper power transmission system operation.

The company gained ISO 9001 certifica- tion of the “Energy Measures Manage- ment” process in 2011. TRANSELEC thus evidenced its commitment to the concept of quality control in the company’s critical processes, such as invoicing and the energy balance for customers and regula- tors.

Moreover, work on the plan for mitigat- ing the effects caused by the presence of corrosive sulphur in power transformer oil continued throughout 2011.

The leader of the band was also killed. In addition, copper prices dropped in the middle of the year and criminal activity went down considerably over the second half of the year, with the total number of kilograms of copper stolen in 2011 down 25% compared to 2010.

TECHNOLOGICAL CHANGES Compensation from Transelec electricity transmission facility investment is made by an annual existing facility assessment (EFA) fee at market prices, which are regularly recalculated according to the process established in current standards. If important technological advances are made for equipment at Transelec facilities, this assessment could be lower and thus prevent overall recovery of investments made.

CREDIT RISK Credit risk corresponding to accounts re- ceivable stemming from power transmis- sion activity has historically been very low because of the limited number of custom- ers, their risk rating and short collection time (less than 30 days).
