Atlantic Canada's
Clean Energy Partner

The Highmark Difference

Highmark Power was founded in 2022 with a simple goal: build clean energy projects properly, without unnecessary handoffs or gaps in responsibility. Backed by one of the most experienced electrical and civil construction teams in Atlantic Canada, we bring deep, practical expertise across electric vehicle charging, solar, battery storage, microgrids, and wind.

What sets Highmark apart is the range of work we handle in-house. Our team spans electrical, civil, and construction disciplines, allowing us to take responsibility for the full scope of a project rather than relying on layers of subcontractors. From project management and renewable energy system design to electrical installation, trenching, excavation, foundations, and site preparation, we do the work required to move projects forward.

That versatility is paired with a strong work ethic and a problem-solving mindset. We understand that clean energy projects don’t always follow a straight line, and we’re built to adapt when conditions change. Our team shows up prepared, works through challenges, and stays focused on delivering results that are safe, reliable, and built to last.

This combination of experience, capability, and accountability is what defines the Highmark approach. It’s how we reduce friction on complex projects, maintain quality from the ground up, and deliver clean energy infrastructure that performs in the real world.

Alex Ross
Operations & Strategy

Alex began his career in international development, focusing on renewable energy access in remote communities. In Nicaragua, he coordinated the installation of 25 off-grid solar systems, gaining foundational experience in project management and community-scale energy. He later moved into the UK’s advanced energy market, where he spent several years leading utility data integrations and managing software partnerships for EV and solar hardware at companies like ev.energy and eliq. During his time abroad, Alex also developed reporting platforms for industry best practices and led solar PV teams in Ghana. He holds an MBA with distinction from Coventry University and has completed executive education in data-driven decision-making at Cambridge Judge Business School. Now back in Nova Scotia, Alex uses his global experience to drive the energy transition in Atlantic Canada. As Director of Strategy and Operations at Highmark Power, he manages clean energy projects, builds team structures, and maintains key utility and hardware partnerships to ensure the successful delivery of complex renewable initiatives.

Ian Harpell
Civil Supervisor

Ian has extensive experience in the construction and heavy machinery industries, starting with his early work on farms in rural East Hants, where he became familiar with operating various types of machinery. He began his career in the forest industry, operating porters and harvesters, and quickly developed a strong foundation in heavy equipment operations. As Ian’s expertise grew, he transitioned into commercial construction, where he focused on heavy equipment and labor, specializing in groundwork and utility installation for subdivisions and industrial areas. For over 10 years, Ian further expanded his skill set working in various lead roles in the building supply industry. During this time, he earned his Class 1 license and spent more than a decade professionally driving, hauling machinery, natural gas, building supplies, and bulk liquid goods. Currently, as Civil Supervisor at Highmark Power, Ian oversees projects and ensures the safe operation of equipment.
