Thanks, Esper, and good morning, everyone. Our operating business had a strong start to the year, delivering record funds from operations as we benefited from our diverse operating assets and contributions from our growth and development activities. We generated FFO of $296 million in the quarter, up 8% year-over-year or $0.45 per unit. These results position us well to deliver on our 10%-plus FFO per unit growth target for the year.
Our hydro assets exhibited strong cash flow resiliency, a reflection of our diversified asset base, inflation-linked power purchase agreements and ability to realize strong power prices. Our wind and solar segments benefited from our recently closed acquisitions including Dervia, formerly Duke Energy's unregulated renewable business, and on path, our U.K. wind, solar and storage platform.
Our Distributed Energy & Storage segment benefited from recent development activities and our Sustainable Solutions segment performed well as we felt the impact from a full quarter of contributions from Westinghouse. Our financial position remains excellent with a strong balance sheet and robust liquidity, positioning us to be opportunistic through the cycle.
Over the quarter, we executed almost $6 billion in financing, taking advantage of pricing with spreads near historic lows. In January, we issued CAD 400 million of 30-year notes at 5.3%, and meaningfully extended our debt maturity profile. Later in the quarter, we issued $150 million of fixed-rate perpetual preferred equity, with proceeds being used to refinance outstanding preferred shares that were scheduled to reset in early April.
The newly issued notes are 70 basis points cheaper than the reset rate of the outstanding shares we redeemed, saving us almost $5 million over the next 5 years. We ended the quarter with $4.4 billion of available liquidity, enabling us to deploy significant capital into growth. Considering public market conditions, our strong conviction in the intrinsic value of our business and our healthy balance sheet position, we allocated capital to repurchase our units in the quarter.
In the last 9 months, we repurchased over 4 million units under our normal course issuer bid. Looking forward, we will continue to allocate capital based on where we are seeing the best risk-adjusted returns, and remain confident we will continue to create meaningful value for our investors.
In closing, we remain focused on delivering 12% to 15% long-term total return for our investors, leveraging our deep funding sources and operational capabilities to enhance and derisk our business. On behalf of the Board and management, we thank all of our unitholders and shareholders for the ongoing support. We are excited about Brookfield Renewable's future, and look forward to updating you on our progress throughout the year. That concludes our formal remarks for today's call. Thank you for joining us this morning. And with that, I'll pass it back to our operator for questions.
