Can Puerto Rico "Build Back Better" and Transform its Energy Grid? Let's Consider the

At Parsan Cross our approach to finding innovative development solutions adheres to two very simple principles: First, any innovative development solution must address a huge problem in the developing world, as evidenced by a correlation to the Sustainable Development Goals (SDGs). Second, this innovative development solution must employ relatively feasible technology appropriately scaled and nuanced for our (Latin America and the Caribbean) region. Periodically, we will showcase an innovative development solution in this thought leadership blog. This week we take a look at Telsa's Powerpack.

1) Who is the Innovative Solution Finder? Tesla (as in the auto maker Tesla motors) and its

acquisition SolarCity.

2) What’s the Huge Problem? Finding a clean, cost effective, grid-scale technology for storing wind or solar energy in less windy and less sunny times.

In Latin America and the Caribbean there is no shortage of wind and solar energy sources. Wind and solar is clean, becoming increasingly inexpensive and is significantly contributing to lowering carbon emissions. However, up until the innovation of recent technologies like the Tesla Powerwall for individual use and the Powerpack for commercial scale use, there was no clean and cost-effective grid-scale technology for storing wind or solar energy on less windy and less sunny days.

3) What’s the SDG Correlation? SDG Goal 7- which is to ensure access to affordable, reliable, sustainable and modern energy for all. Specifically, Target 7.B which is to expand infrastructure and upgrade technology for supplying modern and sustainable energy services for all in developing countries, in particular least developed countries, small island developing States, and land-locked developing countries, in accordance with their respective programs of support.

4) What’s the Relatively Feasible Technology? - Tesla Powerpacks- or the ability to store electricity received from solar panels for days.

The Solar City solar panels capture solar energy, which is then stored in the Powerpacks and converted into electricity. A continuous supply of electricity can be generated completely off grid using a combination of the the solar panels and Powerpacks. The Powerpack is composed of 16 individual battery pods, built with a cooling and heating system adopted from the Model S (Tesla sedan). It weighs 3,575 pounds and can store up to 200 kWh of energy per pack.
