Our Team

As a team, AC Power has been working together to promote alternative energy development while assessing and developing solar projects in landfills and brownfields for several years. Ms. Colston and Ms. Mihelic started working together in 2010 developing landfill gas to energy projects and monetizing environmental attributes of climate change mitigation projects. Together the team can address all aspects of alternative energy development to complete a project efficiently and cost-effectively.

Annika Colston

Founder and President
Annika Colston founded AC Power to bring unique vision to solar PV project development and management on landfill and brownfield sites. Annika has been developing alternative energy projects for nearly two decades and has experience across all aspects of project development. She has worked with all stakeholders needed to make alternative energy projects successful. These stakeholders range from governments to local municipalities, Fortune 500 companies, landowners, utilities and more.

The breadth of her experience makes her capable of solving conflicts and bringing teams together to ensure success. Annika has a unique ability to bring projects to operation on time and within budget. Ms. Colston has been a senior manager of four start-up companies that sourced private and public capital to drive investment in environmentally and socially beneficial projects. Annika is capable of taking projects through the entire development process including origination, contract negotiations, due diligence, financing and investor approvals, permitting, structuring off-take agreements, equipment procurement, construction contracting, and operations.

Prior to AC Power, Annika was Vice President at PV Navigator where she originated and developed over 50 MW of solar projects on landfills and brownfields. From 2011 to 2014, Ms. Colston was President of C2i Methane where she developed and sold a portfolio of landfill gas to energy projects. Mrs. Colston's work experience includes entities that were market leaders such as E+Co, which invested seed capital in sustainable development projects in Africa using innovative investment structures; EcoSecurities, a first of its kind company marketing Kyoto Protocol projects globally; and Blue Source, the largest carbon credit portfolio in the US. During her career, Ms. Colston has worked on solar, landfill gas, anaerobic digestion, coal mine methane, hydropower, and energy efficiency projects.

A pioneer in carbon credit markets, both compliance and voluntary markets, Annika was responsible for sourcing, developing and marketing the first ever climate change project under the Kyoto Protocol to receive carbon credits. She has been innovating ever since. Ms. Colston holds a Masters of City Planning from Massachusetts of Institute of Technology and a Bachelor of Arts in Economics and Environmental Studies from Boston University.

Tracey Mihelic

Tracey Mihelic has 25-years of experience drafting, reviewing and negotiating agreements. She has been working specifically with start-ups developing alternative energy projects for the past ten years. A graduate of Notre Dame Law, her career includes working for the largest law firm and the largest privately-owned company in the world. Tracey has been responsible for ensuring that millions of dollars in purchase and sales agreements, construction contracts, service, supply and consulting agreements do not expose companies and/or investors to unnecessary legal risk.

Early in her career, when brownfields legislation arose, Tracey represented owners and developers in the adoption of such regulations and then in the closure and subsequent development of such sites. She managed legal environmental affairs at the largest privately-owned chemical company involving over fifty plants worldwide. She is comfortable navigating her way through waste sites and plants as well negotiating transactions in a Board room.

Tracey participated in the adoption of the first cap-and-trade compliance market involving air pollutants. She negotiated the first trade sf such pollutants, as well as renewable energy and carbon reduction credits, and drafted the first template for such trades. While at Baker & McKenzie, she adminstered the first Emissions Trading and Climate Change Practice in the world, which remains a leading practice today.

Tracey’s combination of her environmental and regulatory knowledge with project development experience, enables her to provide all aspects of legal counsel from origination, contract negotiations, due diligence, financing, permitting, structuring off-take agreements, equipment procurement, construction contracting, and on-going operations compliance.
