Since 2014, an analysis stage has been included into the remote control to identify significant improvements in order to optimize the operation, e.g. upgrading some critical systems for the operation. To this end, O&M personnel have played an important role to accomplish these improvements. Additionally, a network is being developed through Android applications in order to have real-time information from mid-sized power plants, and an analysis of monitored operating parameters, with which the equipment condition will be determined in real time.
Total volume of water used for generation
In 2014, the company used 3,635.1 Mm3 of water from rivers and lakes where it holds concession rights for power generation. In such process, after the water spins the turbines, it is returned to the river with the same volumes and under the same conditions it was taken in.

Power generation per plant
In 2014 the company generated 1,728.2 GWh, which is below the maximum historical output recorded the previous year by 45.7 GWh. Additionally, the maximum historical output of the Yaupi plant was surpassed (865.6 GWh - 2013). Table 5 shows the production at each plant.

Availability of power plants
The company is performing maintenance on its eight hydropower plants in accordance with a maintenance plan to ensure maximum availability. This plan integrates high-quality tools, such as the 5S methodology, the root cause analysis (RCA), and the reliability centered maintenance (RCM). As a result, in 2014, the weighted availability of Statkraft Perú S.A. was 99.2%
The plant availability in 2014 is shown in Table 6 below.

| Yaupi | 99.7 |
| Malpaso | 99.8 |
| Cahua | 97.3 |
| Gallito Ciego | 99.4 |
| Pachachaca | 99.9 |

Moving forward, the O&M team will integrate the condition monitoring to its management tools. This methodology uses a series of sensors installed in the plant components to measure oil quality, temperature and vibrations. In this manner, plant operators are able to predict the failure probability and act proactively, thus reducing costs and losses due to asset unavailability.
