The CollabSolar project in Bengaluru attempted to reduce transaction costs and attract developers by aggregating the rooftop solar demand of six corporate entities. Key findings indicate that aggregation is most effective within small geographic areas and requires a collective minimum demand of 8-10 million kWh/year to mitigate the risk of individual buyer withdrawal. The project highlighted critical barriers, including corporate charter restrictions for MNCs wishing to invest capital, the need for tripartite agreements with landlords for leased spaces, and the absence of net-metering schemes in Bengaluru at the time, which forced systems to be sized to minimum weekend loads.

The document examines the potential for Indian electricity distribution companies (discoms) to implement green tariffs to attract and retain commercial and industrial (C&I) consumers. It notes that current attempts in Andhra Pradesh and Karnataka have been ad hoc and unsuccessful, contrasting this with the success of tailor-made, consultative green tariff models in the United States. The author argues that for green tariffs to succeed in India, they must involve long-term contracts, regulatory certainty, and a design that accounts for the Indian context of cross-subsidization of residential and agricultural consumers.

The guidebook identifies three primary renewable energy procurement options for commercial and industrial customers in Colombia: on-site turnkey purchases, on-site third-party power purchase agreements (PPAs) or leases, and off-site third-party PPAs. It notes that national policies and falling technology costs have created opportunities for corporations to reduce electricity expenses through these investments.

The document outlines a data-intensive process for local governments to match electricity demand with carbon-free energy resources on an hourly basis. It identifies three essential datasets: hourly load data, hourly grid mix and emissions data, and hourly generation data from additional energy procurements. The guide details four methods for obtaining load data—ranging from actual meter readings to machine learning models—and directs users to resources like the EIA and NREL for grid and emissions information.

The report outlines strategies for U.S. companies to adopt on-site renewable energy, focusing on solar, wind, geothermal, and solar thermal technologies. It details various ownership and financing models—ranging from direct ownership to third-party power purchase agreements—and analyzes the associated financial incentives, operational risks, and corporate benefits such as cost hedging and brand enhancement.

The document highlights that wind power purchase agreements (PPAs) are cheaper than new coal and natural gas plants across most U.S. regions, even without federal tax incentives. It provides specific examples of solar PV projects outcompeting fossil fuels in states like Utah, Colorado, and Georgia. To sustain these trends, the text recommends increasing federal R&D funding, reforming tax incentives to be refundable, and establishing long-term regulatory certainty through carbon pricing or greenhouse gas standards.

The report analyzes renewable energy adoption among the world's largest corporations, finding that 59% of the Fortune 100 and 63% of the Global 100 have set greenhouse gas (GHG) or renewable energy targets. Companies are driven by cost reduction, risk hedging, and consumer demand, utilizing a mix of Renewable Energy Certificates (RECs), Power Purchase Agreements (PPAs), and on-site investments. Key barriers include the need for cost parity with fossil fuels, internal competition for capital, and inconsistent government policies. The report recommends that corporations set time-bound targets and that policymakers extend incentives like the U.S. Production Tax Credit (PTC) and authorize third-party PPAs to accelerate the transition.

The report finds that 48% of Fortune 500 companies have set climate or energy targets, with a notable increase in the smallest quintile of the index. Leading sectors include Consumer Staples, while the Energy sector significantly lags. The report highlights a shift toward science-based targets and 100% renewable energy commitments, noting that 190 companies reported $3.7 billion in annual cost savings from energy efficiency and renewable energy projects in 2016. It provides recommendations for companies, policymakers, investors, and the electricity sector to accelerate the transition to a low-carbon economy.
