Renewable energy is going through a difficult time in Australia, with little cohesion between federal and state governments, and new connection requirements making connecting a renewable energy plant to the grid more expensive. However, if you believe that climate change is real, then renewable energy should be one of the fastest growing industries over the next twenty to thirty years. While growth in the efficiency of solar tends to get more attention, Windfarm technology is also improving in efficiency, and nearly all renewable energy experts see wind farms playing a significant role in the transition to renewable energy. On a much shorter time scale, if Labor wins the upcoming federal election the domestic market for renewable energy should improve markedly. Labor has a policy of 50% renewable energy by 2030, and to achieve this the level of investment in wind farm projects in Australia will need to increase exponentially.

Windlab is ideally placed to take advantage of this, as the development of windfarm sites is perhaps the most profitable part of the wind farm industry. From 2014 to 2017 the company managed an average Return On Equity of 42%, in a time that included significant growth and the cost of listing on the ASX. 

The company is able to achieve this sort of ROE as windfarm developments are sold once all approvals and agreements signed but before construction begins, meaning developing multi-million dollar projects does not require significant capital. For example, take the site of the Coonooer bridge wind farm, a 19.8 megawatt wind farm in North Western Victoria with a total development cost of $48.6 million. After identifying the site with Windscape, Windlab spent only $300,000 in acquiring the land, then spent $2.2 million or research and planning applications for a total investment of only $2.5 million. Windlab then sold 96.5% of the equity in the Coonoer Bridge to Eurus Energy for just over $4.7 million who then funded the construction of the site with help from grants from the state government. In total, Windlab walked away from this transaction with over $4.7 million in cash and a remaining 3.5% stake in the project, a return of over 111% on the initial investment. 

The book value Windlab gives to its inventory as per the 2019 financials is $9.69M, though this is overly conservative as projects are valued at the lower of their cost or net realisable value.  In order to get a more accurate picture of the actual value of Windlab’s inventory, I have tried to assign individual value to some of Windlab’s larger projects.

Lakeland Wind Farm

Lakeland is a 106 megawatt project located in Northern Queensland. While Windlab does not give a breakdown of inventory values, due to its size and stage in the development cycle the Lakeland Wind Farm is probably the single project with the largest value in the companies inventory.  Lakeland is also one of the main causes for the decline in share price over the last six months, as the project was scheduled to reach financial close in 2018 until the primary investor pulled out at the last minute. This delay has meant the project is now subject to new requirements to connect to the electricity grid, which will mean significant additional costs to increase the stability of the connection (this is a change to the nation-wide connection criteria for renewable energy plants designed to address unstable supply).

While these setbacks are undeniably concerning, Windlab claims that the delay has also allowed them to re-tender for more efficient turbines and they have not yet impaired the inventory value of the project, something they have done in the past when projects are compromised. As per their latest announcements Windlab are still confident of reaching financial close on this project in 2019.

If successful, Lakeland will be the largest project brought to financial close by Windlab to date, at 106 Megawatts. For Kennedy, a 56 megawatt project, Windlab received a financial close payment of 5.4 million, while keeping 50% equity in the project. If Windlab is to acheive a similar margin and equity structure for Lakeland, this would result in a payment to Windlab of $10.2 million, with the remaining 50% equity in the project worth at least $10.2 million as well, for a total value of $20.4 million. Given the uncertainty around the project though, a 50% discount would seem appropriate, which gives the project a total value of $10.2 million for our calculations.

Miombo Hewani

Another late stage windfarm project for Windlab is the Miombo Hewani windfarm in Tanzania. This 300-megawatt, $750 million project is Windlab’s first foray into East Africa, and is undoubtedly the companies most ambitious yet. The project received approval from the Tanzanian government in July 2018 and will receive partial funding from the Government of Finland. Windlab have not committed to achieving financial close in 2019 for Miombo Hewani which is understandable given the uncertainty of operations in Africa, but as development approval is already in place as well as some funding arrangements, financial close can’t be too far off. Demonstrating the significant potential value of Miombo Hewani and Windlabs other East African investments, Eurus Energy, a Japanese sustainable energy company that has partnered with Windlab in the past recently bought a 25% stake in Windlab’s east African projects for $10 million USD, valuing Windlab’s remaining stake in their East African portfolio of development projects alone at $30 million USD, or $42.2 million AUD. While this may seem excessive, Windlab stated in their prospectus that their target development margin for Windfarm developments is $250,000 per megawatt of capacity, and from 2015 to 2017 the company had overachieved this, with margins of $260,000 to $490,000 per megawatt. If Windlab was to successfully reach financial close on Miombo Hewani at their target development margin, this would result in a payment of $75 million alone. As a result, adopting the value assigned by Eurus Energy of $42.3 million for the companies East African projects seems reasonable.

Greenwich

The last late-stage development project worth noting in this section is the Greenwich Windfarm in the USA. Windlab officially sold the project in 2018, but will only receive the bulk of their payment of $4 million USD (5.6M AUD) when construction begins. While Windlab have stated they expect to receive this payment in 2019, a group of neighbours have mounted a challenge to the project to the Ohio Supreme Court seeking to dispute the approval given by the Ohio Power Board. . Given the uncertainty of the case, it is probably prudent to discount this payment by 50%, which would mean a value of $2.8 million for Greenwich.

While the projects listed above are the most likely to result in some form of payment in the next 12 to 18 months, Windlab has numerous other projects earlier in the development cycle. These include:

While an exact value for all of these projects is difficult, I have assigned a value of $15 million for the remainder of Windlab's projects.

Excluding Windlab’s asset management business, which I will cover separately, Windlab spends around $6.4 million a year on project expenses, administration and employees. The projects I have listed above are predominantly expected to reach some form of financial close in the next three years, so it seems logical to assign a cost of $19.2 million, or three years of costs to the above calculations. Once a tax rate of 30% is factored in, you are left with a total inventory value of $35.177 as per the below table.

Currently Windlab has significant equity in two large operating or soon to be operating Wind Farms, Kiata, in Melbourne’s North West which has now been operating for just over a year, and Kennedy Energy Park in Northern Queensland that has completed construction and will be connected to the grid in the coming months. Both projects were originally found and developed using Windlab’s proprietary technology Windscape, with Windlab then subsequently selling down equity in the project to help fund development. Windlab owns 25% of the Kiata wind farm and 50% of Kennedy, and combined these two projects have a book value of $43.6 million on the Windlab balance sheet.

Kiata is a 30 megawatt 9 turbine windfarm in Northern Victoria that had its first full year of operation in 2018, with a total profit of $4.57 million for the year. Wind farms are thought to have a useful life of roughly 20 years, after which significant refurbishment costs are needed in order to continue operation. If we discount these future cash flows at a rate of 7%, (which seems reasonable given the relative low risk of an established wind farm) we get a total value for Kiata of just under $43.9 million. This values Windlab’s stake at $10.97 million.

To value Kennedy is a little more complex, as it has not yet begun operation. However, we know that the project is a 56-megawatt project, combining 41 megawatts of wind with 15 megawatts of solar. The plant also has 2 megawatts of battery storage to help modulate supply and allow storage of excess energy in non-peak times. If we extrapolate the annual profit per megawatt of capacity of Kiata in 2018 of $152,353 and assign the same discount rate, we are left with a value for Kennedy of $83.6 million, or $41.8 million for Windlab’s 50% ownership.

Combined, this gives a value of $52.86M for these two projects. 

Windlab’s asset management arm is perhaps the easiest to understand and value. Windlab leverages its expertise by providing ongoing management services to existing wind and solar farms, both that the company has an equity stake in, and to third party independent energy farms or resources. This side of the business is quickly growing, with revenue increasing by 27% in 2018 to $2.97 million, with profit before tax of $610,000, or $427,000 after tax assuming a 30% tax rate. The company signed a significant asset management contract in early 2019 for a solar farm, indicating that they are continuing to grow this business. Given both the significant growth of this area and the broader growth potential of the industry, a P/E ratio of 20 seems coservative, which would value Windlab’s asset management division at 8.5 million.

Lastly, As Windlab has demonstrated ability to use Windscape to develop high-performing Windfarms, it seems only fair to give a value to the Windscape software itself. Windlab is continuing to use this software to identify projects into the future, and the company has proven that this software can provide the company with a significant edge on development projects.  While this is a difficult thing to do, $10,000,000 seems like a conservative valuation, considering both Windlab’s historical performance and the likely growth of the energy sector in the future.

If we add together the values as per the above calculations, we are left with a total value of $113.8 million for the company, or $1.54. As the company is currently trading around the $1.02 mark, this suggests the company is significantly undervalued at its current price.
