Let us design and build your solar net metering project!

What is Solar Net Metering?

Net metering allows an electricity user to install a solar PV facility onsite to generate electricity for internal use, with any excess going to the grid for a credit on future electricity bills. Net metering has been an option in Ontario since 2015 and is governed by Ontario Regulation (O. Reg. 541/05: Net Metering). However, only recently has the price of electricity and the cost of installing a solar PV facility made net metering with solar PV worth considering.

Some key business drivers that the Client should consider when evaluating whether net metering with solar PV makes sense now (2018) are:

  • the risk of electricity price increases;

  • time sensitivity for incentives; cost savings; and

  • the company’s reputation, which will benefit from generating “green” electricity.



Why Solar Net Metering, now?

The Ontario government has mandated that electrical providers, Local Distribution Companies (“LDC”) allow their customers to offset their electricity use by generating renewable energy. This is called Net-Metering. Solar prices have come down and electricity costs have risen. The point where net metering makes sense for your facility may already be here.  Let us tell you if that is the case. Even without a government incentive, there is a business case to be made for Solar Net Metering.  The chart below shows your cost of electricity for the next 30 years. You can determine your own opinion on what the prices of electricity are going to be in the future. The green light below is YOUR Solar system.

Insurance Support and Consulting Advice you can count on! Ask us how!

ORTECH has a long history of auditing, appraising and evaluating renewable energy facilities and energy storage projects across Canada.  This covers all solar power, wind power, biomass, hydro-electricity projects including energy storage facilities. This experience lends itself very well to assisting both insurers and asset managers with insurance issues.  For insurers, ORTECH can help with initial appraisals and with validating claims. For asset managers, we can help reduce your insurance premiums by determining your actual replacement costs.  As engineers who speak finance, our team has worked on over 1200 renewal energy projects in the last nine years.

There are a number of reasons to be engage ORTECH on your next insurance issue or project.

  1. With a specialized process for due diligence, ORTECH’s experience spans multiple renewable energy technologies including solar, wind, small hydro, biomass, and the energy storage market (batteries, flywheel, hydrogen and compressed air). 
  2. Our team has worked on over 535 compliance audits of renewable energy facilities for provincial regulators, and provided technical and financial due diligence to lenders and investors for over 600 renewable energy projects. 
  3. Having trained auditors allows for faster turnarounds on project deadlines.
  4. ORTECH has a team of engineers that understands renewable energy capital and operating costs, and financial models.

Our team can provide you with the following assistance:

For Insurance Companies:

  • Initial project appraisals: determining if the project has been commissioned correctly, determining if the forecasts match up with the operating logs, reviewing the ability of the project to meet its financial obligations, e.g., debt repayments
  • Claims Support:  ORTECH can review claims including their validity, the amount of loss that is claimed, and the revenue loss due to disruption of operations.
  • Replacement Cost:  ORTECH can review existing replacement cost values or develop new ones for ever-changing markets, including removal or disposal of existing or non-operational equipment.

For busy Underwriting departments, ORTECH has been successful at turning around projects quickly and even developing new, more efficiency processes when working with various clients.  Our experience and knowledge will allow a claims manager or underwriting executive to make the right decisions.

For Asset Managers:

  • Replacement Cost:  ORTECH has been engaged to develop new or updated cost information for asset managers when their insurance has to be reviewed.  Our clients find they get less resistance to reduction in premiums when a third party independent engineer’s report accompanies their insurance application.
  • Claims Management:  Determining claimed expenses can be tricky. You want to be made whole but determining the costs and proving them is difficult. ORTECH’s reputation and experience allow the insurance company to recognize the validity of the costs.  It generally speeds up the process when the insurance company understands your efforts to generate a valid and realistic value for your claim.

With the costs of building renewable energy projects declining and the constant pressure to improve returns on investments on your renewable energy facilities, it is best practice to review the value of your facilities and go to the market for insurance estimates every couple of years.  Your premiums are linked to value of your facilities, so it is always good to hire an independent consultant to provide you with a proper valuation, supported by current data. You should discuss any changes to your insurance policy with your debt financing firm.

ORTECH looks forward to speaking with you about how we can assist you with your renewable energy insurance needs.  For further information, please contact Michael Tingle.

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.
