Tesla Megapack | Massive Energy Storage | Large Scale Renewable Storage

The Tesla Megapack has been announced by Tesla today. The Megapack is designed for utilities and large-scale commercial customers and could be a real game changer for those in remote areas or looking for large amounts of portable renewable storage. Let’s learn more!

Tesla announced the Megapack today – as a potential replacement for “peaker” power plants, which help the grid when it’s overloaded. Pacific Gas and Electric (PG&E) will deploy several Megapacks at Moss Landing on Monterrey Bay in California. There are also three other locations PG&E are looking at optimising.

The Tesla Powerpack, released in 2015, is Tesla’s current offering for large scale energy storage – the array in South Australia has a capacity of 129 MWh and can deliver 100 MW of power.

The Megapacks are substantially more powerful – each Megapack can store up to 3 megawatt hours (MWh) of energy at a time, and it’s possible to string enough Megapacks together to create a battery with more than 1 GWh of energy storage, according to the press release.

This gives the product comes with some serious grunt: “A 1 Gigawatt hour (GWh) project provides record energy capacity—enough to power every home in San Francisco for 6 hours.”

“Every Megapack arrives pre-assembled and pre-tested in one enclosure from our Gigafactory—including battery modules, bi-directional inverters, a thermal management system, an AC main breaker and controls. No assembly is required, all you need to do is connect Megapack’s AC output to your site wiring.”

According to The Verge, Tesla has been deploying record numbers of Powerwalls and Powerpacks in 2019 – which has created issues with battery shortage, undoubtedly a pain for anyone wanting to order the Powerwall 2 in Australia, for example: 

“Tesla deployed 415 MWh worth of Powerwalls and Powerpacks in the second quarter of 2019, a record for the company. Throughout 2018 and into early 2019, the company had to scale back the number of Powerwall and Powerpack products it deployed because it needed the batteries to support the dramatic increase in Model 3 production.”

Is it going to be easier to wait for the Powerwall 3? Watch this space.

  • Microgrid – you can build a localized grid which is able to disconnect from the main power grid. Sound 
  • Renewable Smoothing – ‘Smooth out the intermittency of renewables by storing and dispatching when needed’
  • T&D (Transmission and Distribution) Investment Deferral – ‘Postpone costly grid infrastructure upgrades by supplying power at a distributed location to defer the need to upgrade ageing infrastructure’. (Learn more about T&D savings with energy batteries by clicking here)
  • Voltage Support – the Megapack can add voltage or remove it to help maintain the grid.
  • Frequency Regulation – The Megapack can rapidly change charge or discharge energy in response to changes in grid frequency.

Hornsdale Power Reserve saves $8.9m in 6months

Hornsdale Power Reserve – also known as the Tesla South Australia battery, the 129MWh solar/energy storage battery has saved the state $8.9m in six months, according to Renew Economy and their analysis of spot market pricing in 2018.

The cost of the Hornsdale Power Reserve hasn’t been made public, but at ~$800 per installed kWh the cost comes out to around $100m (with around $50m paid by the government), which fits the whispers we’re hearing around the traps.

The partnership between Tesla and South Australia was inked in July last year as Elon Musk and then-Premier Jay Weatherill decided on Neoen’s Hornsdale wind farm as an installation spot. The Tesla Battery was then completed on November 24, ahead of its December 1 operation deadline (Musk made a bet with Weatherill/South Australia that Tesla would install the Powerpack batteries by December 1 or the project would be free).

According to an analysis undertaken by RenewEconomy and investigated further by Clean Technica, The battery saved $5.7m in its second quarter of operation. It bought power at an average price of $79/MWh and sells it at $191/MWh (a figure somewhat distorted by a very power-hungry January – with that month removed the price goes down to $141/MWh). The estimated savings for the full 2018 are expected to be around $18m. 

It’s important to note that the battery is still trading 30MW (of its total 100MW) of capacity so there is space to expand operations should the government be so inclined.
