Riau Book - The construction of Electric Steam Power Plant (PLTU) Tenayan Raya in Pekanbaru, Riau, until now reportedly has reached 95 percent. It was targeted will be finished completely on July 2016 and may able to be used well.

This statement was said by the manager of Construction Conducting Unit of PLTU Tenayan Raya, Sugiharto to the reporters during his visit to the construction, Saturday (23/04/2016).

"Until now, the progress of construction at the PLTU as a whole has reached 95 percent. This includes unit 1 and unit 2. Special unit 1 currently has reached 97 percent," he said.

He explained, for unit 1 now is entering the stage of the steam blow that is the pipe cleaning stages. "The purpose of this steam blow is to clean the pipes around the main pipe and also the super heater pipe. Currently it has been already conducting 130 times the steam blow. The first step we have to clean the super heater 25 times and the results had met the standards. Until now we had cleaned main piping (main steam pipe)105 times steam and we see the result is getting better. We expect this blow steam can be completed today, "he explained.

He explained after the stage of steam blow, it has begun to set up a synchronous phases. "Stages of this synchronous generator in the sense that we have been able to pull out the electrical energy, we already turn a turbine and the generator also has issued electrical energy, then we will connect to the existing electrical system in Sumatra through 150 kV transmission network," he continued his explanation.

For this synchronous phases were planned on the middle of May. "Because after the steam blow, we are still going to dismantle the pipes steam blow and we will still do the permanent installation of the pipe so it takes 7-10 days for entering the next stage Load rejection," he explained again.

Speaking about the amount of power that can be felt by the public at the beginning of the distribution of power by the power plant, Sugiharto said to trial early stage (stage synchronous) power delivered from 30 percent to 80 percent, but if possible would peak at 100 percent.

"But it all depends on the condition of the system. This means we need to set in terms of safety or of the generator system itself so that we can reach the stage of 100 percent. Well, if it could reach 100 percent we will shut down again to prepare for the next stage namely load Rejection stage. This stage is the provision of a load ranging from 50 percent to 100 percent. We would be released gradually, when it succeeded then we will enter the next stage, "he explained. (RB/sil)
