Blockchain – Power Ledger in Puerto Rico?

Posted on by — No Comments ↓

Blockchain tech provider Power Ledger in Puerto Rico – the Australian company are looking to help the struggling Caribbean island with its ongoing energy woes by implementing their technology into microgrid resources.

We posted about Tesla’s input last October when they had a look at a microgrid in Puerto Rico – apart from the initial six, we haven’t seen many more of the Tesla Powerpacks installed – although hundreds of Powerwalls were also sent to help. Since PREPA (Puerto Rico Electric Power Authority) has a $9 billion USD in debt to Wall Street it’s a difficult situation for PR.

According to Bloomberg, Power Ledger have hired Dante Disparte, a Puerto Rican grid resiliency and security expert who is also CEO of advisory firm Risk Cooperative. Disparte spoke of the need to shore up the grid before any further problems – noting that it won’t be long until Puerto Rico sees more wild weather: 

“The next hurricane season is but three weeks away and the grid is not reliable — that is part of the urgency,” said Disparte.

Power Ledger are working with factories and regulators to help companies on the island buy solar panels and battery storage. They’ll then use the blockchain technology to allow companies to trade energy with each other, and to sell supplies to employees or the community. This exchange will be able to take the forms of non-traditional (or, depending on which way you look at it, very traditional) exchange – for example you’ll be able to buy power via cash, cryptocurrency (e.g. Bitcoin or Ethereum) or even labour. 

Puerto Rico Electric Power Authority CEO Walter Higgins said in an interview last week that it will be another couple of months until they finish restoring electricity to the remaining 25,678 customers still in the dark following the storms ~8 months ago. So obviously they need to start looking at measures that will help them next time there’s a problem.

Disparte said this isn’t going to be about “just building back the old grid waiting for the next crisis and the next wave of financial constraints.” They’re trying to completely change the way Puerto Rico can address issues like this in the future and this is an inspiring real-world usage of this technology.

Power Ledger’s investors will be able to make investments in Puerto Rico energy assets later this year using their POWR tokens. If you want to learn more about it please click here to view our article on Power Ledger.

Microgrid in Puerto Rico? Tesla Steps In.

Posted on by — No Comments ↓

In the wake of Hurricane Maria’s landing on Puerto Rico on September 20, the country has been almost completely without power and a majority of the 3.4million residents aren’t able to use fridges, air conditioning, or pump potable water. Enter the possibility of a Microgrid in Puerto Rico – Elon Musk’s Tesla have offered their support to the country by sending hundreds of their Powerwall energy storage batteries – with many already on the ground and more to come. They’re initially being sent to high priority locations such as hospitals which are currently using expensive and hefty gas-powered generators.

Tesla Powerwalls and Puerto Rico

According to news sources such as Bloomberg and Engadget, Tesla is sending hundreds of the Powerwalls to Puerto Rico in an attempt to help shore up its shattered energy infrastructure. The Powerwalls will be paired with solar panels to generate energy while the country works on restoring its main grids. Some of the Powerwalls have already arrived in Puerto Rico and Tesla employees are on the ground assisting in the installation of required infrastructure. According to some sources, grid power won’t return to the entire island for another six months so they’re going to have to look at some options – which may include the full scale renewables – with small grids far more resilient than transmission lines and central grids. These microgrids could be connected to a central grid but also isolated if required. 

Renewable energy expert Tom Rogers told The Washington Post “You look at islands like Dominica, Anguilla, and other islands affected by the recent hurricanes, I’ve spoken to a couple of the utilities, and they say they would prefer to rebuild using distributed generation with storage, and just trying to reduce the amount of transmission lines. Because that’s where their energy systems fail. It’s having these overhead cables.”

Tesla Microgrid in Puerto Rico

After the initial Powerwalls being sent, there have been others talking about the much larger, industrial-size Tesla Powerpack grid scale storage solution and whether this could be an option for the commonwealth moving forwards. Clean Technica report that the island’s utility company, PREPA (Puerto Rico Electric Power Authority), has a massive $9 billion USD in debt to Wall Street and Puerto Rico itself is in debt to the tune of $123 billion (and $74b of them are in defaulted bonds currently in bankruptcy court). In short, the country is in serious financial strife and its grid is virtually worthless. Ricardo Ramos, the CE of PREPA, told CNN the island’s power infrastructure had been basically “destroyed”. 

There’s a possibility of just handing the grid over to its creditors and ‘start again’ – and this could perhaps be the impetus for Tesla to create microgrids across the country with its Powerpack batteries (they scale from 50kW up to 100MWh) – certainly a herculean task but who other than Elon Musk would take something like this on? 

Musk’s team are currently installing Tesla Powerpacks in South Australia under less critical circumstances but it’ll be an interesting litmus test to see if Tesla could roll something out on such a massive scale.
