• SSE raised about $708 million through its first Australian green bond issuance, expanding its access to international sustainable finance markets.
• Investor demand reached 2.5 times the amount offered, creating the third-largest orderbook for a senior Kangaroo corporate bond.
• The deal takes SSE’s outstanding green bonds to about $8 billion, strengthening its position among the UK’s largest corporate green bond issuers.

UK energy group SSE has entered Australia’s bond market for the first time, raising about $708 million through a two-part green bond issuance.

The transaction gives SSE access to another major institutional capital pool as it finances its energy investment programme. It also comes as companies seek greater flexibility in debt markets amid elevated global borrowing costs.

Known as Kangaroo bonds, the securities are Australian-dollar bonds issued in Australia by overseas borrowers.

SSE’s debut attracted demand worth roughly 2.5 times the bonds available. The orderbook was the third largest ever recorded for a senior Kangaroo corporate transaction, according to the company.

SSE taps Australian investors for green capital

The offering was divided into two tranches.

SSE issued about $425 million of five-year green bonds, which mature on August 20, 2031. They carry a fixed coupon of 5.6%.

A further $283 million was raised through 10-year green bonds. Those securities mature on August 20, 2036 and carry a fixed coupon of 6.3%.

SSE swapped both tranches back into sterling after issuance. The company said this produced a weighted average funding cost of 5.7%.

The bonds have an average maturity of seven years.

Strong demand provides SSE with another source of long-term capital while reducing reliance on any single funding market. That diversification can become particularly important as interest rates, inflation and geopolitical risks reshape borrowing conditions.

Green bond portfolio approaches $8 billion

The Australian transaction is SSE’s 12th green bond since it entered the market in 2017.

Following the latest issuance, SSE and its subsidiaries now have approximately $8 billion of green bonds outstanding.

The scale places green finance at the centre of the company’s broader capital strategy rather than treating it as a specialist funding channel.

For investors, green bonds provide debt exposure while directing proceeds toward eligible environmental investments. For issuers such as SSE, they can broaden the investor base supporting large-scale energy infrastructure.

That relationship is becoming increasingly important as utilities finance renewable generation, electricity networks and other infrastructure required for the energy transition.

SSE broadens its funding base

The Australian deal forms part of a wider financing programme during SSE’s 2027 financial year.

The company has raised approximately $1.49 billion through hybrid bonds. Those securities carry an average cost of 4.6% and an average maturity of 6.6 years.

SSE has also raised around $2.57 billion of new senior debt. That funding has an average cost of 5.3% and an average tenor of 8.2 years.

The figures point to a deliberate effort to spread borrowing across instruments, maturities and international markets.

For corporate finance teams, the Australian issuance also highlights the growing international reach of sustainable debt. Green capital is no longer concentrated within European institutional markets.

Large borrowers can increasingly seek climate-focused investors across currencies and regions, then use hedging arrangements to manage their underlying financing exposure.

What investors should watch

SSE’s 2.5-times oversubscribed transaction provides evidence of institutional demand for green-labelled corporate debt, even as financing costs remain elevated.

The more important issue for investors will be how that capital translates into eligible assets and long-term returns.

Green bond frameworks face continued scrutiny around allocation, reporting and measurable environmental impact. Governance therefore remains central to the credibility of expanding issuance programmes.

For SSE, entering Australia opens another route to finance its investment requirements while building relationships with a wider institutional investor base.

For the broader sustainable finance market, the transaction shows how green bonds are becoming embedded within mainstream global corporate funding. As energy investment needs rise, access to multiple capital markets could become as important as the volume of financing itself.
