An Island’s Path to 100% Renewables

The grid of the future lies 850 miles off the coast of Portugal, on an island in the Azores called Graciosa.

The island has always been dependent on fossil fuels. But in 2018, that changed. That’s when a group of developers kicked off a hybrid wind-solar-battery storage power plant to slash diesel consumption.

The plant consists of 1 megawatt of solar, 4.5 megawatts of wind, and a 6 megawatt/3.2 megawatt-hour energy storage system.

The power plant has changed Graciosa’s energy mix. In 2020, there were 128 days when the island was entirely powered by renewable energy. And Graciosa is now saving 190,000 liters of diesel fuel per month.

One of the reasons: a piece of control software installed by Wärtsilä, called GEMS. It uses machine learning to balance the renewables and storage on Graciosa’s grid with inputs from meters, heating and cooling systems, and weather forecasts.

And GEMS is helping grids across the world balance high amounts of variable renewables with energy storage.

In this episode, produced in collaboration with Wärtsilä, we’ll talk with Duarte Silva, the engineer who oversees the island’s power system. We’ll also talk with Luke Witmer, a data scientist who manages R&D for Wärtsilä’s energy dispatch systems.

Wärtsilä creates smart, flexible power technologies to enable a cleaner grid and put the world on a path to 100% renewable energy. They’re helping clients worldwide meet their clean energy goals in an efficient and cost-effective way. Learn more about how Wärtsilä helped the island of Graciosa transform the grid with the GEMS software.

The Magnitude of 24/7 Zero-Carbon Energy

In 2017, Google became the first major company to reach 100% renewable energy through corporate renewables procurement.

But it was also the first major company to acknowledge that 100% renewable is not really 100% carbon-free.

So Google set out to go further, and match procurement on an hourly basis, to reach the promised land of 24/7 zero carbon energy.

It’s going to be hard. But Michael Terrell, Google’s Director of Energy, thinks it’s doable. In this episode, Michael talks with Shayle about how it could even become a new norm for corporate and state commitments.

But first: What will it take to get there?

Shayle and Michael cover the datasets, the accounting mechanisms, and the massive scale of transactions needed to make it possible. They break down about Google’s efforts to shift computing load across its fleet of data centers. They talk about the power of corporate buyers to push policymakers to clean up grids.

Where current clean technologies fall short, Google is looking at new technologies to fill in the gaps. They talk about that lineup of potential solutions, such as long-duration storage, carbon capture and storage, geothermal, advanced nuclear, and lithium-ion batteries.

And finally they tackle cost and scalability: Will organizations without the capital and expertise that Google enjoys be able to follow its lead?

How Cheap and Abundant Can Clean Power Get?

A decarbonized power sector will unlock massive opportunities across nearly every other sector, either via direct electrification or indirect electrification via the production of low-carbon fuels, like green hydrogen.

But here’s the rub. Many of the companies that are working on these solutions rely on pretty heroic assumptions around the cost, availability and cleanliness of electricity in order for the economics to work.

To put it bluntly, many decarbonization business models hinge on a cell deep in their spreadsheets that has 1- to 3-cent per kilowatt-hour electricity. Is it a realistic assumption?

To tackle that question, Shayle Kann turns to his colleague at Energy Impact Partners, Andy Lubershane, the Senior Vice President of Research & Strategy.

They survey the technologies that depend on this super cheap, super abundant power, such as EVs, space heating, carbon removal, green hydrogen and industrial heat.

Then, they examine the talk of cheap renewables, covering the difference between cheap wholesale and more expensive delivered prices. They break down the variables that make up the difference between wholesale and delivered prices, namely transmission, distribution and capacity factors.

So what are the solutions that could shrink that gap?

What Are ‘Transformational’ Utilities Doing Right?

First they ignore you. Then they laugh at you. Then they fight you. Then they transform?

This week: a look at some positive trends guiding the utility sector. What are power providers that are leading the energy transition doing right? We’re joined by Julia Hamm, the president and CEO of the Smart Electric Power Alliance.

We’re talking about SEPA’s 2021 utility transformation profile — a survey and ranking system of over 130 electric utilities in the US.

There are thousands of power companies. That means different flavors of corporate goals, management styles, and approaches to building clean energy. Julia’s going to help us understand what they are. Why is utility progress more like “change management” than traditional Silicon Valley-style disruption?

Then: how utilities will benefit from Biden’s big infrastructure push.

Plus, the solar census: what will job growth look like in a post-pandemic world?
