Siemens supports Philippines in energy trading


Siemens installs its Spectrum Power energy market management software at the Philippine Electricity Market Corporation (PEMC). PEMC is an autonomous group market operator that operates and maintains the Philippines Wholesale Electricity Spot Market (WESM).

This technology will allow market participants to more efficiently exchange and share energy resources, including renewables like wind and solar, based on generation and demand needs. Currently, 25 percent of the Philippine's energy mix is coming from renewables including hydro and geothermal, but as resources like wind energy increase in this region which is expected, there is a significant need to manage these resources efficiently in real-time and dispatch power where it's most needed.

Siemens software will help PEMC analyze and systematically establish energy requirements and allocation of the grid for week-ahead, day-ahead, and hour-ahead time frames.

In real time, the solution automatically determines the lowest cost generation and renewable mix to meet demand while maintaining the security of the grid.

The cost-saving potential with this new energy market management software increases significantly due to the proper estimation of current system status, the use of short-term demand forecasts that gauge demand accurately, and five minute real-time market dispatch.

Reliability is also increased through realistic dispatch results, accounting for accurate energy reserves and ensuring the reserves are available when needed during outages and demand and renewable generation fluctuations.

Furthermore the software provides market operators greater insight to assess and manage operating conditions in the power grid using state estimation, contingency analysis, prediction of demand, and generation dispatch across the PEMC marketplace.
