RRI Energy, Inc. (NYSE:RRI) has made a big success on the market recently. After a resistance level at 4.30, currently RRI is trading at $4.42, which is +2.55% price up on its stock.

During the last week, the company reached the remarkable volume of over 5 million traded shares.

Following the chart, we can see that the current uptrend may be a sign the RRI shares will continue to rise, as well as its stock price.

In its first quarter report for 2010, RRI Energy reported free cash flow of $61 million, compared to $45 million for the first quarter of 2009. However, the company’s net loss was higher than the year before. Still, RRI Energy is in a good position to benefit from improvement in market conditions.

Last year First Energy announced it planned to move from the Midwest ISO to PJM in 2011. In connection with that move, three of RRI’s power plants will also move to PJM. If the transfer turns to be successful, the future forward revenue from all capacity sold in the integration auctions will be approximately $54 million.
