A proven dividend player with reliable cash flows
That brings us to Capital Power (TSX: CPX), the Canadian stock Iâd confidently put my $7,000 into today. This Edmonton-based power producer is known for delivering dependable cash flows through its renewable and thermal power assets spread across North America.
After surging by 46% over the last year, CPX stock currently trades at $55.50 per share with a market cap of $8.6 billion. The stock rewards its investors with an attractive quarterly dividend that translates into a strong annualized yield of 4.7%.
Strong financials driven by smart moves
Capital Powerâs business model is already built on stable energy assets, and it recently added more fuel to its growth story. In the first quarter of 2025, its net profit was slightly lower than a year ago, but the companyâs adjusted funds from operations climbed by 87% year over year to $1.57 per share, reflecting how efficiently itâs running operations.
Last quarter, Capital Powerâs revenue also rose sequentially by 10% to $988 million. These results were mainly boosted by the companyâs continued focus on portfolio diversification and strong asset utilization, especially in the U.S. market.
Growth strategy anchored in future demand
Another key factor that gives Capital Power its unshakeable appeal is how it’s continuing to invest in the future. It recently announced a $3 billion deal to acquire two major natural gas-fired facilities in the U.S., adding over 2.1 gigawatts of flexible generation capacity.
These assets serve high-demand markets and are expected to be fully accretive as theyâll start adding to Capital Powerâs earnings right away. This move also strengthens the companyâs presence in a key U.S. power region, where electricity demand continues to rise due to rapid growth in data centres and industrial development.
A long-term dividend pick you can count on
Beyond acquisitions, Capital Power is also developing multiple battery storage and wind projects across Ontario and Alberta, expected to add another 350 megawatts of contracted capacity. Moreover, it has wrapped up coal repowering work at its Genesee facility, setting the stage for cleaner and more efficient output going forward. With strong dividend visibility, expansion into key U.S. markets, and a well-funded pipeline of growth projects, Capital Power fits perfectly into any list of safe dividend stocks to buy today. For long-term investors seeking stable income and growth, this company could be the anchor your portfolio needs right now.
