RMI Business Renewables Center Aims to Boost US Corporate Solar, Wind Energy Purchases with Market Analyzer Platform

Investing in and making use of emissions-free, local renewable energy resources is one of the highest profile and most significant ways leading corporations have addressed the rapid rise in prominence of corporate social responsibility and “triple bottom line” business and industry sustainability that has taken place the world over in the last decade or so. Doing so boosts the credibility and legitimacy of their “green” energy and corporate sustainability efforts by demonstrating their commitment to improving social and environmental conditions, as well as contributing to local, national and the international drive to reduce greenhouse gas emissions and avoid prospective worst-case climate change scenarios.

It also has provided the impetus for Aspen, Colorado-based Rocky Mountain Institute’s (RMI) Business Renewables Center (BRC) to develop the renewable energy Market Analysis Platform, an online market data resource and analysis tool that corporations and other large-scale solar and wind energy purchasers and investors can use to better understand market economics and pricing trends regionally, down to local site levels, across the US.

Two-thirds of Fortune 100 list of the world’s largest corporations and nearly 50 percent of Fortune 500 companies have publicly disclosed sustainability commitments, RMI BRC highlights. Ninety-six jumbo-sized corporations have joined RE100 and committed to 100 percent renewable energy. Solar Magazine spoke with BRC Market Analyzer project manager, RMI Electricity Practice Group Manager Stephen Abbott to gain and share insights regarding the ambitious software platform’s development, what it offers, and how corporations and other large-scale purchasers of electricity can use it to help meet their renewable energy, sustainability and climate change action goals.

A Software Catalyst for Corporate Solar and Wind Energy Procurement

RMI’s BRC is working to catalyze corporate procurement of 60 gigawatts (GW) of renewable power capacity by 2030. Available to all 200+ BRC members, the Renewable Energy Market Analyzer will help both buyers and developers of renewable energy projects build a more complete, accurate picture of wholesale electricity market economics across the U.S. based on real price histories for individual grid connection locations.

As Abbott explains in a June 15 RMI Outlet blog post:

Large corporations, universities, and municipalities are increasingly interested in procuring renewable energy at scale due to a combination of increasingly ambitious sustainability targets and falling costs.

During live online demonstrations, BRC project team members highlight how those responsible for investing in or purchasing solar or wind energy on the part of corporations or other large-scale utility customers can use Market Analyzer to improve the quantity and quality of relevant data and information at their fingertips, and then use it to enhance decision-making. For example, Market Analyzer can be used to:

  • Identify points in Michigan, Minnesota, Virginia, and California as good sites for wind farm development
  • Reveal areas in Southeast and parts of West USA where there is currently no access to open markets for corporate buyers
  • Demonstrate how the value of a wind and/or solar farm can vary even within a state, such as Oklahoma, and highlights areas of congestion

As Abbott explained, Market Analyzer “is built using publicly-available data from market operators, a levelized cost of energy (LCOE) calculation, and a proprietary algorithm to model hypothetical project revenue.” The platform’s processing engine “produces an estimated value calculation for approximately 4,300 nodes, or grid connection points, across all seven U.S. independent system operators (ISOs) covering 39 states.”

“This software tool is able to identify high-value areas for wind and solar energy regionally. It enables people to create scenarios, then compare and contrast potential prospects regarding [solar or wind energy] transactions, identifying the most important questions they should be asking when meeting with developers,” Abbott elaborated.

Macro and Micro Views of Regional U.S. Solar and Wind Energy Economics

RMI BRC project team members are engaged in a continuous effort to improve the resolution, or “granularity,” of Market Analyzer’s data sets, as well as its geographic coverage. “We capture about 4300 data points around the country, calculating and aggregating results when end users first enter the system,” Abbott explained.

Using a primarily visual graphical user interface (GUI), end users can view the results of pooled regional analyses, then zoom in on results for specific locations. The amount and quality of underlying regional market data does vary, however. As Abbott explains: “Some ISOs publicly disclose data of all node locations. For those we are quite granular.” That isn’t the case in other areas, primarily across the midsection of the U.S. and in the Southeast.

“We’re looking for mechanisms that will allow us to scale to some 32,000 nodes nationwide,” he continued. “Sometimes the nodes are located at specific substations, but probably not at the ‘busbar’ where renewable energy systems tie in to grid, but certainly within the area surrounding that node.

Roughly speaking, “there are maybe a dozen or two major [grid price] nodes around the country. There are around four hubs where nodal prices are aggregated, pulling all that data together to determine electricity prices and customer charges. These might be located at a substation, while in other instances they may just be a data collection point in the region where electricity prices are aggregated by ISOs.”

A Surge in Corporate Solar, Wind Power Purchases

Large companies have added more than a rated 7.5 gigawatts (GW) of renewable power capacity to North American grid networks each year since 2014, according to BRC’s Deal Tracker. With Market Analyzer, BRC focuses on deregulated wholesale electricity markets where ISOs monitor, gather and store prices and other market data, Abbott told Solar Magazine.

Notably, a sharp spike in capacity took place in 2015 as corporate investments in and purchases of wind power surged due to the anticipated expiration of the wind power production tax credit (PTC), one of the federal government’s two primary market incentives. Similar “boom and bust” cycles have occurred when it appeared likely the federal solar investment tax credit (ITC) would be allowed to expire. Both were extended and are being gradually phased out as part of a Congressional federal budget compromise between Republican and Democratic Party members at the end of 2015.

That said, growing adoption and expansion of corporate sustainability programs, along with the magnitude and expected continuation of declines in solar and wind energy costs, continue to fuel interest and investment in purchasing renewable energy from third-party solar or wind energy systems developed by independent power producers or utility “green energy” purchasing programs.

Identifying and Analyzing Critical Solar, Wind Energy Economics Factors

Solar Magazine: Solar Industry News and Insights

There are a variety of critical, variable factors large-scale purchasers of renewable energy need to consider besides price, however, Abbott points out. Entering into a typical virtual power purchase agreement (VPPA) entails the buyer paying a fixed price per unit of energy and/or power over a specified term, say 10 to 15 years. In return, the purchaser receives emissions-free electricity and any revenues that may result from selling energy in local or regional wholesale markets at specific points over time, as well as those from selling any associated renewable energy certificates (RECs) for which they may gain rights of ownership.

How a Virtual Power Purchase Agreement Works

Those prices are unknown when the VPPA is entered into and they will vary over the life of the its term. Swapping fixed VPPA payments for floating rate returns, especially over long time horizons, conveys significant financial and credit risks, and these may vary widely depending on average market prices of conventional and renewable grid power and energy in any one given area, their expected future values over the term of the VPPA, and the actual costs experienced over time. Added to these is the specific nature of and composition of local or regional wholesale markets and their respective rate regimes.

As Abbott explains in the BRC blog post: “Buyers must consider more than just the cost of energy when evaluating these transactions, but the opacity and complexity of wholesale energy markets makes this analysis challenging. To address this market challenge, Rocky Mountain Institute’s Business Renewables Center (BRC) is launching a software platform that combines recent market data with regional cost models to help potential buyers and others understand where wind and solar projects are more likely to be economically attractive.” comment↓
