Let us help you plan and build your next project!

ORTECH has worked on over 850 solar projects in Ontario, either for the IESO, equity investors or debt providers.  We uncover risks you need to understand, not provide answers you want to hear. Our role is clear, provide practical advice to ensure you can make your expected returns, service your debt financing obligations and can be compliant with your offtake contract.

Our experience leads to the right answer, right away with our results/reports/reviews including a path forward.  Communication is at the core of our values. We tend to over-communicate with our clients and strive to ensure our customers never have to call for a project update.

We are very dynamic and reactive to the market.  We have been on the forefront of the solar power industry since 2009.

We have a different approach, we strive to help our clients, regardless if it means a project for us. We regularly help developers, equity investors and debt providers connect.  It's one thing most engineering firms do not do. We feel its helps the industry, and we do not charge a fee to make introductions.

ORTECH’s 40 years of experience in atmospheric sciences combined with state-of-the-art modelling and analysis provide dependable results

ORTECH can develop ground up solar resource assessment for input into the financial model. This is completed in conjunction with the project design in order to advise the optimum selection of equipment, fixed or tracking racking systems for example. The resource assessment will use site specific solar resource information triangulated from nearby reference stations.

ORTECH uses industry standard software packages to estimate the solar resource at the Project site, Meteonorm and PVSyst. These tools provide a high quality estimate of the potential output of a solar array. However, ORTECH's experience in the application of these tools including use of site specific weather data and appropriate degradation and loss factors is vital to ensure the software presents an accurate estimate of the potential energy generation from the solar farm.

An ORTECH solar resource assessment report typically includes:

  1. General Project Description;
  2. Predicted Monthly Energy Output,
  3. 30 Year Cumulative Energy Output,
  4. Interpolated Radiation and Temperature Data Set,
  5. Array Geometry,
  6. Inverter Output Distribution,
  7. Module Mismatch Losses,
  8. PVSYST Model Input / Output, and
  9. Results/Conclusions and Uncertainties.


ORTECH has worked extensively on solar farm economics, estimating costs and the performance of operating solar farms.  More importantly, we have experience in working closely with equity sponsors throughout the development process to revisit the financial model and input assumptions at every step of the development process.

The proforma financial models of solar projects are driven by several major factors:

  • Solar Resource and Power Price (i.e. Revenue)
  • Capital Cost and Operating Costs
  • Cost of Senior Debt

To better understand and manage these factors, ORTECH has developed a strong in-house solar resource assessment team that can optimize solar farm layout, explore the suitability of various solar panel models and is fully integrated with the financial modelling process. We also have developed a thorough understanding in estimating capital and operating costs through forecasting and backcasting work on past projects.

IESO Dispatch Management Services done right!

If you need a system that allows you to respond to the dispatch calls from the IESO, ORTECH has the technical and operational experience to help.

ORTECH has Independent Electricity System Operator ("IESO") dispatch management experience. We are currently providing these services to a 10 MW ground-mount solar facility including automation of the bid/dispatch instruction process. If you need these services, ORTECH would be happy to discuss a strategy with you.


The IESO has organized market participants into two groups:

  1. Dispatchable, and
  2. Non-dispatchable.

With dispatchable participants, they must submit bids or offers for generation, and adjust their operations based on IESO dispatch instructions.  This is part of the IESO objective to control the balance of supply with demand.

If your renewable energy project is connected to a transmission station, you are most likely required or will be required to take part in this. As a registered market participant for a dispatchable generation facility or dispatchable load facility, you must ensure that the facility complies with its dispatch instructions.

ORTECH can help developers figure out how and who will manage this new requirement. 

The key reasons ORTECH is uniquely qualified to assist market participants with their dispatch management needs:

  1. ORTECH has a dedicated computer already set-up that includes the configurations required for access to the IESO Portal;
  2. ORTECH specializes in due diligence and auditing of renewable energy projects and utilizes a well-developed process to help manage scope, schedule and budget;
  3. ORTECH engineers “speak finance” with an understanding of both the technical and financial aspects of project development and operations; and
  4. ORTECH is able to provide opinions on technical and financial aspects with a complete team experienced in renewable energy project development and operations.

Renewable Energy Site Identification and Prospecting   Efficient, Effective and Done Right

Developers struggle with identifying land for various renewable energy projects.  There are so many variables:  RFP guidelines, land classifications, connection options and permitting risks.  That’s a lot of expertise and effort required to vet just one site.

ORTECH has a solution that allows developers to concentrate on real projects and reduces the wasted time of investigating potential land sites.

Solution: ORTECH has a database and GIS tool that can identify land for your project.  This solution takes into account the IESO rules, connection points, environmental permitting risks, land classes, and amount of land needed for your project to be viable.

What you GET!  A fully vetted list of project sites that can be developed into renewable energy projects.


  1. Determine what technology you want to develop including nameplate, general location and land characteristics. This is done through a survey.
  2. ORTECH presents license map to client. This high level map shows zones of Ontario that would potentially be viable for a project site.
  3. Client chooses zones of interest.
  4. Using a process of elimination, ORTECH will start to narrow down land zones where projects may work through a risk scoring method. Interconnection, land classes, environmental issues, land ownership (crown land etc)
  5. Initial project zones are presented to the client for approval.
  6. Determine project land owners.
  7. Contact Land owners.
  8. Present list of properties for acquisition.
  9. Negotiate Lease options.
