International investment heats up in the renewable energy sector

My appraisal practice has changed significantly in the last year. Whereas I spent the last few years visiting struggling or proposed luxury home subdivisions, hotels, tourist projects and golf communities in foreign countries, my clients have reduced their appetite for such risky ventures. Nowadays more than half of my work involves the valuation of land for solar photovoltaic energy production, AKA solar farms.

There seems to be a great appetite for cross-border investments in renewable energy infrastructure projects. Such projects are able to attract capital from investors not needing high returns, but focused rather on steady, long-term yield from contractual government or utility company payments that reimburse them. Renewable energy infrastructure seems a safe and easy investment compared to foreign casinos and luxury vacation resorts.

Each week brings one or more announcements of cross-border renewable energy deals. Last week, Swiss-owned Adiant Capital Partners sold a 37 megawatt UK solar farm to UK-owned Foresight Group. Canadian-owned Northland Power has announced a $177 million IPO for wind farms in Canada and Germany. Australian fund AMP Capital is entering the Japanese renewables market. The Blackstone Group (U.S.) has announced that its second energy fund, $4.5 billion in size, focusing on renewable energy assets worldwide, has been oversubscribed.

There is construction risk, of course, but many transactions are also structured as sale-leasebacks of the land the renewable energy projects are built on. And management risk of renewable energy infrastructure is nothing compared to commercial real estate, unless you have Homer Simpson pushing the buttons.

Renewable energy infrastructure is now so mainstream that Google and Apple are investing, including a Norwegian-owned project in Utah that I recently appraised, in which Google will be partially financing the development of a $157 million solar plant.

Another example of a multinational solar farm venture I evaluated was a duo of Ecuadorian solar farms to be developed by a German manufacturer financed by private money from the U.S. The deal fell through because the German CEO didn’t understand that his firm had to own or buy the properties they would be mortgaging and that licensing and power purchase agreements had to be finalized before the investor would commit funds.

Valuation methods for solar farm land

The approach of choice is the sales comparison approach, which works well in California due to the large number of publicly recorded transactions. Solar farm appraisers are not always so lucky to find verifiable sales, though, in foreign countries and “non-disclosure” U.S. states (such as Utah, New Mexico and Texas) and sometimes must turn to a land residual approach to valuation, in which land values are imputed by valuing the completed project and then subtracting development costs and expected entrepreneurial profit. The recent reduction in development costs has justified rising values of land with power purchase agreements and public approvals.

The role of technology in increasing solar farm land values

The last few years have seen escalating land values in the U.S. southwest for land which has secured conditional or special use permits for solar photovoltaic energy production as well as power purchase agreements with utility companies. The reason for this land price appreciation has been because the value of such land is a residual of the cost to develop it for solar PV use, and the cost of PV technology has fallen more than 50% in the last several years, but rates for electrical usage have not fallen.

Much of the deflation in solar PV development costs is the result of cheaper technology being imported from Taiwan and China. I have recently been on a research trip to Taiwan, for example, to study their solar PV and wind power innovations.

There may be a temporary halt in falling solar PV development costs, however, as the U.S. government in February has imposed “antidumping” penalties on Chinese and Taiwanese manufacturers. The antidumping duty on Taiwanese solar cells is now 20%, and the new duties on Chinese solar panels will range from 39 to 52%.

Also, with the price of oil falling more than 50% in the last year, there may be less public pressure to subsidize renewable energy projects. These combined forces may temporarily stop the tide of rising values for solar farm and wind farm land.

This may be a temporary hiccup, though, in a long-term trend of renewable energy sources to replace fossil fuel technologies as our predominant power production technology, as production costs are likely to continue to fall as technology advances. Compare these advances to shale oil hydraulic fracturing technology, which is only more expensive than conventional on-shore drilling. Ten years from now, the world of energy production is likely to be quite different than today.

The Issue of Client Pressure on Valuation Results in International Appraisals

Costa Rican subdivision overlooking the Gulf of Nicoya

It has been almost 3 months now since I’ve done a foreign appraisal assignment, and there are a couple of reasons for this.

1. I’ve had a large increase in business in appraisals of domestic “solar farms” (photovoltaic energy generation) in the U.S. Southwest, and

2. Foreign appraisal assignments have been offered to me with “conditions” that would compromise the ethical code most appraisers follow, conditions which would require me to deceive lenders or the U.S. Internal Revenue Service.

Here are some situations:

1. An owner of a high-end condo on Grand Cayman Island was fishing for an appraiser who could guarantee that his condo was worth $2 million in every year that he has owned it since 2006. But the Caymans have had the same rise and fall as every other Caribbean condo market, and it would not seem reasonable to anyone, including the Internal Revenue Service, that it had been worth the same amount in every year since 2006. The fact that he did an e-mail broadcast of these appraisal conditions to other appraisers could also end up getting him into trouble with the IRS, who provides rewards to whistleblowers.

2. Developers of ocean view residential subdivisions in Brazil and Costa Rica wanted to me to provide current market value opinions on their subdivisions without having me visit their properties. Yes, I was already familiar with their subdivisions, but a determination of current market value requires me to know current market conditions in these respective localities, requiring that I visit and analyze competing subdivisions, too.

“Desktop appraisals” (appraisals done without a property inspection) have limited reliability for overseas properties and are not likely be taken seriously by lenders, either. I also need to see if amenities, such as the guardhouse, pools, recreational areas are operational and that infrastructural development is continuing.

Appraisal of proposed solar farms in Ecuador

      Corn farm at almost 10,000 feet above sea level

In my native land of southern California, it is becoming common to turn marginal agricultural land into photovoltaic solar farms, particularly in Kern County, the Mojave Desert and Imperial County.  Some parcels have a unique advantage if they are located near a power grid substation, near a major city (Los Angeles or Las Vegas), and have enough water available for keeping dust off of the machinery (about one acre-foot of water per 20 megawatts of production. One acre-foot is equivalent to the water needs of about 4 households.)

Many landowners in these areas, most of whom are absentee, hope to get phone calls from solar farm builders who want to lease or buy their land.

Other countries have “Green initiatives”, too, and such initiatives give hope to owners of marginal agricultural land in Ecuador.

The farms I appraised were at opposite ends of Ecuador.   One was located about 20 km north of Quito, Ecuador’s second largest city, at an elevation of almost 10,000 feet above sea level, and one was located in the low-lying Guayas province about 50 km west of Guayaquil, Ecuador’s largest city.

        High voltage transmission lines on subject property

Both farms had high voltage electrical transmission towers on their properties, but only the Quito property was near a power grid substation, 2 km away in Pomasqui, which provides power to the entire northern half of the Quito metro area, having a total population of 1.5 million residents. This solar farm operator planned to supply power directly to the high voltage lines on his properties, which can be done in Ecuador because the power grid has single government ownership in Ecuador vs. the multiple private ownerships that sometimes govern power lines in parts of the United States.

This being the case, that anyone with a high voltage transmission tower on his property in Ecuador could supply electricity to the Grid, greatly increases the supply of available sites and provides little or no financial advantage to the landowner compared to his neighbors.  Neighboring farms with power lines near the Guayas property were selling in the range of $900 to $2000 per hectare.  Not a lot of value there. 

The property near Pomasqui was very difficult to appraise due to its unique flaws -- steep slopes and lack of accessibility; solar farms are not considered viable on slopes exceeding 10%. The escritura (deed) indicated that the property had been purchased for 1,680,000 sucres in 1997.  That sounds impressive until one learns that the Ecuadorian sucre was replaced by the dollar in 2001 at an exchange rate of 25,000 sucres per dollar, making the purchase price effectively worth about $67. Then again, it is common in Latin America to record false purchase prices in order to minimize transfer taxes.

To make matters worse, the borrower did not even own the land serving as collateral for the loans. Never was a purchase mentioned, either.  There was a misunderstanding of the concept of "loan collateral". A collateral lender expects the loan proceeds to go towards immediate purchase of the land; otherwise, what else is there to provide security for the loan?

Another complication for this assignment was that the client, a private lender, ordered an “as is” appraisal, and the borrower did not even have licenses yet for the solar farms. So the properties had to be appraised as agricultural land, which was a big disappointment to the borrowers.

In any case, there is not yet an established “market” for solar farms in Ecuador, making valuation a very difficult process, and even if there was one, 99% of the value is in the improvements and little value is in the land. 

PS: I have received several inquiries asking who is financing construction of solar photovoltaic cell farms, but the only financiers that I am aware of can only lend upon substantial existing assets. Any solar photovoltaic construction lenders are welcome to introduce themselves in the comments that follow.
