State of the US Renewables Market: Rapid Growth and a ‘Lot of Risk’

The worlds of power markets and renewables are colliding, and nobody seems quite sure what to do about it.

Though still a miniscule fraction of grid power in many places, renewable energy resources have momentum on their side. As they grow, they alter the functioning of the markets in ways that look different from traditional generation.

Wood Mackenzie launched its Power & Renewables Summit last year to unpack these changes, and in the intervening time, the signs of change have grown clearer. Deployment queues in every U.S. region show a dramatic turn toward wind and solar, proving this is not just a groovy California thing anymore.

Once built, these resources, which are essentially free to dispatch but cannot be called on command, push down wholesale prices, initiate transmission congestion and create sharp ramping needs for dispatchable power plants.

​Explaining the plummeting cost of solar power

Researchers uncover the factors that have caused photovoltaic module costs to drop by 99 percent.

The dramatic drop in the cost of solar photovoltaic (PV) modules, which has fallen by 99 percent over the last four decades, is often touted as a major success story for renewable energy technology. But one question has never been fully addressed: What exactly accounts for that stunning drop?

A new analysis by MIT researchers has pinpointed what caused the savings, including the policies and technology changes that mattered most. For example, they found that government policy to help grow markets around the world played a critical role in reducing this technology’s costs. At the device level, the dominant factor was an increase in “conversion efficiency,” or the amount of power generated from a given amount of sunlight.

​NREL Awarded $2.8M from ARPA-E to Develop Low-Cost Thermal Energy Storage

The U.S. Department of Energy's (DOE's) National Renewable Energy Laboratory (NREL) has been awarded nearly $2.8 million in funding from DOE's Advanced Research Projects Agency-Energy (ARPA-E) to develop a system for grid electricity storage and power generation. The system includes a high-temperature charging device, low-cost thermal energy storage modules, a high-performance heat exchanger, and a closed-loop Brayton cycle turbine.

As NREL Principal Investigator Zhiwen Ma explains, "When electric power is cheapest, electric heaters will ‘charge' the storage modules by heating stable, inexpensive solid particles to more than 1,100 degrees Celsius. And when it's time to discharge this energy, the hot particles will move through a heat exchanger to heat a working fluid that drives a high-efficiency closed-Brayton combined cycle attached to an electric generator."

DOE Announces Funding for Advanced Wind Turbine Generator R&D

The U.S Department of Energy's (DOE's) Wind Energy Technologies Office has announced a Funding Opportunity Announcement (FOA) entitled "Advanced Next-Generation, High-Efficiency, Lightweight Wind Turbine Generator." The primary objective of this FOA is to develop a lightweight, more efficient wind turbine drivetrain system (gearbox and generator, or direct drive generator) that minimizes the use of rare earth magnets and contributes to the scaling of wind turbine power capacities beyond 10MW. Projects funded through this funding opportunity will result in the design, fabrication, and up-tower testing of advanced multi-megawatt-scale wind turbine prototype drivetrains. This work will further DOE's goal to reduce the cost of energy from wind by decreasing nacelle and tower mass, reducing O&M and replacement costs, and improving performance.

Study says Minnesota can economically reach renewable energy goals by 2050 

Minnesota can economically get 70 percent of its electricity from renewable sources by 2050, as prices for wind, solar and battery storage continue to fall, a study has found.

The deployment of more solar and wind generation would be no more costly than new natural gas power, a cheap source of electricity, according to the study done for the state Department of Commerce. Enough solar generation could be added cost-effectively by 2030 to meet Minnesota’s ambitious solar-power goals.

How Will Wind Industry Find the Answer? With WISDEM

When doctoral student Katherine Dykes visited the National Wind Technology Center (NWTC) at the National Renewable Energy Laboratory (NREL) eight years ago for an inaugural workshop on combining wind energy with systems engineering, she saw a similar PowerPoint slide at each of the presentations: "What is systems engineering?"

"Thankfully, I haven’t seen it in a while," said Dykes, who joined the U.S. Department of Energy's (DOE's) NREL in the summer of 2011 and now works as a senior engineer at the NWTC.

From there, Dykes has spread the word throughout the wind industry about systems engineering. This interdisciplinary approach takes everything into account so that customer needs and wind turbine design, performance, and cost are all equally important.

Can the price of rooftop solar keep falling?

Rooftop solar's growth has slowed nationally, but its price to customers continues to fall, leaving market watchers questioning its future.

In 2017, the installed price of residential photovoltaic (PV) solar continued its 20-year price decline, but at a slower pace than the 2009 to 2013 glory years. Tariffs on imported solar products and the rising cost of finding customers slowed the price decline and flattened growth, leaving installers, policymakers and utilities asking if the price will keep falling and, if it does, how low it will go. Changing solar incentives make this question especially important.

​California regulators prod utilities to start drafting roadmap to 100% clean energy

The sum of renewables procurements from California electricity providers is not enough to achieve the state's 2045 target, and regulators are struggling for solutions.

California's 44 electricity providers are updating their formal plans to meet the state's new 60% renewables by 2030 mandate and its 100% clean energy by 2045 goal.

Investor-owned utility (IOU) regulatory filings say they have adequate renewables to meet the 2030 requirement and will begin procuring again after that. Customer choice aggregator (CCA) filings say they will procure adequate renewables to meet the 2030 mandate, though they do not specify how or when. And electric service providers (ESPs) say they don't do long-term procurements.

Combined wind and solar made up at least 20% of electric generation in 10 states in 2017

Wind and solar electric generation, including small-scale solar photovoltaics, reached or exceeded 20% of total generation in 10 states in 2017. During some months in 2017, wind accounted for more than 50% of in-state electricity generation in Iowa and Kansas, and solar accounted for more than 20% of in-state electricity generation in California. Total annual generation from wind and solar in the United States in 2017 reached 8% for the year and peaked at 11% in April of that year.

Wind and solar resources are unique among sources of electricity. Unlike most other generating technologies, grid operators generally do not dispatch wind and solar generation because these generators produce electricity only when the associated resources are available. Even so, some wind and solar plants may allow for limited dispatcher control on a minute-to-minute basis. For example, by setting operating levels to slightly lower than achievable levels for current conditions, operators have some flexibility to increase or decrease output in response to market signals.

Led by Surging Residential Sector, Q2 US Energy Storage Deployments Grow 200% Year-Over-Year

Highlights from the latest U.S. Energy Storage Monitor.

For the first time ever, the U.S. saw more home energy storage than front-of-meter storage deployed in a single quarter.

According to the latest U.S. Energy Storage Monitor from the Energy Storage Association and Wood Mackenzie Power & Renewables (formerly known as GTM Research) 156.5 megawatt-hours of energy storage were deployed in the second quarter of 2018, triple what was deployed in the second quarter of 2017. The residential segment led the way, growing tenfold year-over-year.

Residential deployments were concentrated in two states, California and Hawaii, which together account for 72 percent of megawatt-hours on the quarter. Wood Mackenzie Power & Renewables senior analyst Brett Simon notes that there are no signs these two states will relinquish their residential market lead; however, he posits that there is an exciting race for the No. 3 spot. Simon points to both Massachusetts with its new SMART program and Arizona, which may see some new tariff structures, as key contenders.
