Project Updates

October 25, 2019

Dear neighbor,

AES is happy to report we have successfully completed the first phase of commissioning of the Huntington Beach Energy Project (HBEP). This includes the first start-up of both gas turbines of the new plant and the Steam Blows which are critical to the successful operation of the plant. The Steam Blow Restoration Period is nearing completion and we anticipate the Steam Purity Run phase will begin as early as the week of October 28.

Huntington Beach Energy Project Commissioning Process

We received some concerns from our neighbors regarding noise during the Steam Blow phase. While every step of the commissioning process results in better plant performance, including noise, we asked our engineers and operators to re-evaluate the remaining commissioning activities to identify additional potential noise-reduction strategies we could employ throughout this temporary work phase.

Typically, the loudest noise encountered during building any project incorporating a steam turbine is created by steam blows during the commissioning process, which is now complete.

AES is exploring further temporary measures for controlling some of the noise during the remainder of the commissioning process.  However, during the next phases of the HBEP commissioning process our neighbors may experience noise levels above normal for the area.  Commissioning activities will occur 24 hours a day, 7 days a week, and we expect the noise levels to decrease as we progress through each step of the commissioning process. Noise related to commissioning activities is temporary and not part of normal operations. These temporary conditions are part of a very short but necessary period to bring the systems online.  When the new plant is ready for normal operation, AES must conduct noise testing in the community to demonstrate that noise levels will meet our permit requirements.

We are working as safely as possible to quickly complete this process. We want to reiterate that this is temporary.  This will not be part of normal operations. Once in operation, the new power plant will be much more efficient, will reduce emissions and environmental impacts and provide for greater electrical reliability than the old boilers built in the 1950s that are being replaced.  So please pardon any temporary disturbance while we bring our new plant online.
