Since 1996, Optimal Energy has been collaborating with clients to integrate low-cost, reliable and safe energy into a balanced resource portfolio to meet the energy needs of today's dynamic economy. Our primary objective is to help clients recognize opportunities and gain competitive advantages in the energy services sector. The Optimal team provides a range of consulting services to utilities, program administrators, state and federal energy offices, regulatory commissions, advisory councils, and advocacy groups with an interest in creating wealth, promoting local jobs and increasing the productive use of scarce resources. In all of our work, we adhere to four key values:

We are responsive to client's needs and perspectives. Our management staff have worked in entrepreneurial positions, for consulting firms serving both the public and private sectors, on the staff of public utility commissions, as field implementation managers, and in engineering or other technical firms. We know how to complete projects on time and within budget.

Our work is analytically sound. Our staff brings extensive technical and quantitative expertise to the analysis of demand-side energy programs and technologies. Our industry-accepted analytical tools incorporate and address all the important factors affecting society's investment in clean energy resources. These tools have been refined over the last ten years and thoroughly tested. Public utilities commissions, public power authorities and state energy offices in several jurisdictions rely on our research and software tools as the foundation for important public policies affecting their communities.

We ground our analyses in reality; we are not content to simply take the academic view. Optimal relies on 'on-the-ground' implementation experience to inform its work. Our experience is rooted in real-world circumstances gathered in the field and from our close relationships with partner organizations who have staff implementing customer-specific energy projects. Market conditions and customer attitudes are key inputs to our analyses and inform our program design recommendations. Our priority is to assure clients that their clean energy programs are practical and well understood by all stakeholders.

We present our results in a clear and accessible way. We recognize that diverse stakeholders have unique perspectives and values regarding energy resource decisions. We respect those differences of opinion and work hard to develop customer-centric presentation formats. We strive to present our fact-based reports and recommendations in a manner that fosters greater understanding and supports decision-making. Our communications clearly state the pertinent issues, identify opportunities as well as risks associated with our recommendations, and provide an overview of the relevant context that may affect management decisions.

In summary, Optimal Energy helps clients:

  • lower their risk profile by integrating clean energy solutions into long-range resource plans;
  • improve customer satisfaction by providing additional choices and control over their energy bills; and
  • reduce environmental impacts.

In almost every jurisdiction in North America, the benefits of our clean energy solutions can be realized at or below the cost of competing supply-side resources.
