The Power Purchase Agreement: Three Words Nova Scotians Will Come to Love

by Dan Roscoe, President of Renewall

Energy costs are rising, but with Renewall, Nova Scotians will have a powerful tool called Power Purchase Agreements (PPAs) to lock in lower rates for longer.


Energy costs in our province have been unpredictable, leaving many Nova Scotians wondering how to manage their electricity bills. Power Purchase Agreements (PPAs) provide a solution, offering long-term price stability and access to clean, affordable wind energy. Once reserved for large corporations, PPAs will now be available to homeowners and businesses alike, ensuring a more secure and sustainable energy future.

What is a Power Purchase Agreement (PPA)?


A Power Purchase Agreement is a contract between an energy provider—like Renewall—and an energy buyer, such as a business, municipality, or even a community. These agreements, which typically span 10 to 25 years, allow customers to secure a predictable rate for their electricity, shielding them from market volatility and rising costs.


Types of PPAs

  • Physical PPA: The buyer directly receives renewable electricity from a specific project, such as Renewall’s energy from the Mersey River Wind farm. With Renewall, customers will receive a Physical PPA, meaning they will transition from NS Power to Renewall for their electricity supply once service begins.
  • Virtual PPA (VPPA): The buyer financially supports a renewable project, receiving credits or financial benefits rather than direct electricity. For example, Bullfrog Power offers a VPPA where customers purchase renewable energy credits in addition to their regular utility power bill.
  • Community PPA: A group of consumers collectively invests in a renewable energy project to share its benefits. This model holds potential for future adoption in Nova Scotia.


Why PPAs Are a Game-Changer for Nova Scotia

Wind Energy: The Province’s Lowest-Cost Power Source

Wind energy is already the most affordable source of electricity in Nova Scotia, with recent contracts securing rates lower than the current average cost of energy. Renewall ensures customers benefit from these savings by purchasing clean energy from wind farms under long-term PPAs, providing stable and predictable electricity costs for years to come.



Protection from Rising Electricity Prices

A PPA ensures stability, shielding businesses, institutions, and municipalities from price spikes. Imagine a municipality that locks in its electricity costs today—while others are exposed to future price hikes, they’ll be enjoying predictable, lower costs, gaining a financial edge and becoming more competitive over time.



Boosting Local Renewable Energy Growth

PPAs are not just good for those who sign them—they benefit all Nova Scotians by accelerating renewable energy development. More wind energy projects mean more local jobs, a stronger economy, and greater energy independence. A growing renewable sector also enhances grid stability and reduces reliance on expensive imported fossil fuels.


How Nova Scotians Can Benefit from PPAs


Businesses & Institutions: A Smarter Energy Future

From corporations to municipalities and universities, organizations that lock in long-term renewable energy deals can reduce their costs while meeting sustainability goals. Global giants like Google and Amazon have used PPAs for years to secure low-cost, clean energy—now Nova Scotian businesses have the same opportunity.



Residential Customers: Stability for the First Time

For the first time in Nova Scotia’s history, homeowners and small businesses can secure long-term protection against electricity rate hikes. By choosing a PPA, residential customers gain predictable, affordable energy—allowing them to budget with confidence and avoid the stress of fluctuating power bills.

The Potential for Community-Based PPAs

Community energy projects are gaining momentum worldwide. By pooling resources, local groups or municipalities could invest in shared renewable energy projects, ensuring collective benefits for participants. While not yet common in Nova Scotia, this model presents an exciting future opportunity.


The Future of Energy in Nova Scotia: A PPA-Powered Province


Supporting Nova Scotia’s Clean Energy Goals

The province has committed to achieving 80% renewable energy by 2030, and PPAs will be a critical tool in achieving this goal affordably. As we transition away from fossil fuels, PPAs offer a way to accelerate adoption while keeping costs low for consumers.



Why Now is the Time to Act

With demand for renewable energy growing and wind capacity increasing, now is the perfect time for homeowners, businesses, institutions, and municipalities to explore PPAs. Those who act early will secure the best rates and ensure long-term energy stability.
