Our Vision

We have been visionaries since day one

Rose Energy has gained trust from its partners, we work with Chinese state-owned energy companies, a Japanese multinational, a Thai partner and Malaysian investors all having agreed to partner our operations and will provide their very high-end experience, cooperation and assistance on development and expertise for the construction of our projects.

It is our ambition and wish, to establish a frame work of Power Plants in Cambodia over the coming years, unseen in the region, making Cambodia independent of power imports and stronger in running and controlling their own more stable balanced and reliable grid.

Additionally, Rose Energy is experimenting on the implementation of vertical wind power units that can solve many existing utility and urban solutions for power cost reductions, which is a welcome offer towards the daily growing circle of customers.

As the Imperial Empire activities have also under their umbrella other very interesting items as our Rose Plastics PVC plastic factory we will set up for a large group of installers and entrepreneurs the option to purchase small scale items as Solar panels Tier 1, charge controllers and inverters , and windmills any size to purchase at their convenience, helping them to avoid enormous investments and have less cash flow problems.

Not the price but long-lasting quality solutions and happy customers are our goal.
