Published

on

MENLO PARK, Calif., April 14, 2025 /PRNewswire/ — Mainspring Energy Inc. announced today that it has secured $258 Million in a Series F financing round to expand the company’s linear generator power business and operations as it grows in both manufacturing and customer sales. The company also has added two Board members with deep energy and tech industry operating experience – Tom Linebarger, former Chairman and CEO of global power solutions leader Cummins, and Bethany Mayer, former CEO of public technology company Ixia and former Board member of energy infrastructure giant Sempra.

“Mainspring brings a unique and winning solution to the market.”

Global investment and transformation company General Catalyst led the raise, joined by Amazon’s Climate Pledge Fund, DCVC, Temasek, Marunouchi Innovation Partners, M&G Investments, Pictet Group, and Mainspring’s earlier investors including Lightrock and LGT Bank, Khosla Ventures, and Gates Frontier, among others.

Mainspring Linear Generators deliver significant advantages in cost, reliability, and flexibility, including the ability to dynamically switch among fuels. The products are also fully dispatchable, and their low emissions make them easily sited and permitted anywhere. They are scalable from a single unit to a grid-level array, delivering from 250 kW to 100+ MW of power in any increment needed. The product is easily manufacturable and can scale to meet growing power needs.

This combination of flexibility benefits gives customers unmatched optionality in power deployment and has led to the products’ rapid adoption in segments as diverse as data centers, EV charging microgrids, commercial buildings, residential developments, cold storage facilities, hospitals, and wastewater treatment plants.

“I am excited to join the Mainspring Board of Directors at this critical time for energy,” said Linebarger. “The demand for innovative solutions to meet power needs has never been higher, and Mainspring brings a unique and winning solution to the market.”

“Mainspring’s linear generator technology has the potential to accelerate the future of low-carbon energy and support a more resilient electric grid – two important goals for Amazon as we work to become net-zero carbon across our operations by 2040,” said Thomas Selby, corporate development manager with Amazon’s Climate Pledge Fund. “We are excited to collaborate with the talented team at Mainspring as they work to scale their business to meet growing energy demands for new and existing customers.”

The two new Mainspring Board members bring valuable operational knowledge and expertise in the power generation and hardware industries. Linebarger, who will be joining the Board on behalf of General Catalyst, is the former Chairman and CEO of global power leader Cummins Inc.  Previously he served as SVP at GE Capital, Chair of the U.S.-China Business Council, and in other corporate leadership roles. Mayer is an experienced public company executive, CEO, and board member with roles at leading corporations including Sempra, Box, HP, Cisco, Apple, and various startups.

“Mainspring is fortunate to have the support of many of the top energy investors in the world, with a strong international perspective, as we prepare for our next phase of growth,” said Mainspring CEO and Founder Shannon Miller.  “This round, along with the growth of our Board, strengthens our capacity to deliver more power – faster and at scale – around the world. It also positions us to advance U.S. leadership in innovative power technology and bolster national energy security.”

About Mainspring

Mainspring Energy began commercial shipments of its innovative linear generator products in 2020 and today has hundreds of megawatts in field operations and advanced development for leading Fortune 500 companies and utilities. With this latest round of financing, Mainspring has secured more than $800 million in financing to advance its goals in delivering innovative power generation to meet growing global demand.

PS Hogan highlights investments from Spring Economic Update 2026: Canada Strong for All to support Canada’s sport system

Published

on

By

CALGARY, AB, May 2, 2026 /CNW/ – In Budget 2025, we outlined our plan to build Canada Strong. Since then, we have moved fast to build the major infrastructure, homes and industries that grow Canada’s economy and create lasting prosperity; empower Canadians with better careers and a more affordable life; and protect our communities, our borders and our way of life.

We delivered concrete savings for Canadians while supporting key national priorities and keeping investments focused on results. We are maintaining a strong fiscal position, with the Spring Economic Update 2026 showing that projected deficits are lower over the fiscal horizon and that we are on track to meet our fiscal anchors.

The Spring Economic Update 2026 is the next step in our plan to build Canada Strong for All. It provides a clear update on the strength of Canada’s economy, giving Canadians confidence in our plan. It delivers targeted relief to make life more affordable, support workers and accelerate the construction of homes and major infrastructure. It also strengthens Canada’s competitiveness and economic growth while investing in strong, safe communities across the country.

Today, Corey Hogan, Parliamentary Secretary to the Minister of Energy and Natural Resources and Member of Parliament for Calgary Confederation, met with athletes at Foothills Athletic Park to highlight key investments in sport from the Spring Economic Update to build stronger and safer communities.

The Government of Canada is investing $755 million to support and expand Canada’s sport system, which will help athletes safely train and perform at the highest levels. This will increase sport participation across the country by strengthening national sport organizations, infrastructure and local sport communities.

Canada’s new government is transforming our economy from reliance to resilience. The Spring Economic Update 2026 ensures all Canadians can participate in building Canada strong and share in its success. Other key measures include:

The Canada Strong Fund — Canada’s first national sovereign wealth fund. This will invest in key, strategic Canadian projects and companies. While Canadians will benefit from these nation building projects through jobs, economic growth and greater security, the government is determined to ensure that Canadians also have a stake in the projects themselves. That’s why a unique and important feature of the Canada Strong Fund will be its new retail investment product. This allows Canadians to receive financial returns as we build Canada strong together.Team Canada Strong — a new nationwide effort to recruit, train and hire 80,000 to 100,000 new skilled trade workers by 2030–31. This initiative creates new opportunities for Canadians and attracts the workers needed to build more homes and major projects at speed and at scale.Building Stronger Communities — by making communities safer, more connected and more resilient. We are building more homes, getting tougher on crime and fraud and funding essential infrastructure, including small craft harbours that sustain coastal communities and local jobs. We are also investing to build healthier, safer and stronger Indigenous communities.

Our new government is building a Canada that is not just strong, but good; not just prosperous, but fair. A Canada that is not just for some, most of the time, but for all, at all times. We’re building Canada strong, for all.

Quote

“The Spring Economic Update 2026 builds on the momentum of our budget, combining strategic investments with sustained fiscal discipline to keep building Canada Strong for All — delivering prosperity today and strengthening our economy for tomorrow. At this pivotal moment in Canada’s history, we’re charting a course through the fog of uncertainty and global headwinds with strength, determination and ambition — and building one strong Canadian economy, by Canadians, for Canadians.”
— The Honourable François-Philippe Champagne, Minister of Finance and National Revenue 

“The Government of Canada is building Canada Strong by investing in what brings us together — our people, our communities and our athletes. By strengthening the foundation of Calgary and  Canada’s sport system, we are building a resilient economy and strong communities for all.”
— Corey Hogan, Parliamentary Secretary to the Minister of Energy and Natural Resources and Member of Parliament for Calgary Confederation

Quick Facts

The Spring Economic Update 2026 proposes to provide $755 million over five years, starting in 2026–27, and $118 million ongoing to Canadian Heritage to support Canada’s sport system to: Host and compete with the best: $50 million over five years to bring more world-class sporting events to Canada. Funding will be tied to legacy-building projects that deliver lasting benefits well beyond the events themselves. Facilities built or upgraded for major events will continue to serve communities, support grassroots participation and strengthen local sport systems for years to come. Support our athletes in performing at the highest levels: $45 million over five years and $8 million ongoing to help our athletes train, compete and perform, including support for better mental health and funding that will be linked to robust safe sport measures and frameworks. These actions will strengthen the sport system and respond to some of the findings of the Final Report of the Future of Sport in Canada Commission while the government continues to consider all of its Calls to Action. Get more Canadians involved in sport: $660 million over five years and $110 million ongoing for National Sport Organisations, increasing funding that has remained largely unchanged since 2005, so that they can invest in a strong and safe sport system and grow participation among children and youth nationwide.

POVADDO AND PROLEGIS ANNOUNCE STRATEGIC PARTNERSHIP TO EXPAND ACCESS TO PUBLIC POLICY PROFESSIONALS FOR OPINION RESEARCH

Published

Partnership connects policy professionals using Prolegis’ modernized Congressional platform with Povaddo’s exclusive paid research panel, combining forces to serve the policymaking community

ST. LOUIS and WASHINGTON, May 2, 2026 /PRNewswire/ — Povaddo, a leading provider of public opinion and policy elite research, has announced a strategic partnership with Prolegis, a nonpartisan technology platform serving thousands of policy professionals in Congress and the advocacy community. The partnership will expand the reach of the Povaddo Panel—an exclusive network of nearly 5,000 public policy professionals worldwide—while providing Prolegis users new opportunities to contribute their expertise to policy research.

Prolegis provides nonpartisan technology solutions designed to modernize Congress. Built specifically for the policymaking community, the platform serves as a natural intersection where policy professionals and issue advocacy campaigns meet, making it an ideal environment for connecting researchers with the experts shaping public policy.

Beginning this month, users of the Prolegis platform will be invited to join the Povaddo Panel and become eligible to participate in research studies tailored specifically for public policy professionals.

“There is no shortage of so-called ‘expert network’ firms, but Povaddo is setting the standard when it comes to building the most rigorous and credible network of public policy professionals in the U.S. and beyond,” said William Stewart, President of Povaddo. “What makes Prolegis the right partner is the quality and relevance of their community—these are precisely the professionals our clients most want to hear from. Prolegis users are actively engaged in policy work daily, making them ideal participants for our research studies. This partnership will meaningfully accelerate our efforts.”

“Prolegis exists to serve the policy community with tools that make their work more effective,” said Jim Gianiny, CEO of Prolegis. “Partnering with Povaddo allows our users to contribute their expertise in a new way and take part in rigorous research that helps organizations better understand the policy landscape. It’s a natural extension of what our platform already does: connecting policy professionals with the resources and opportunities that matter to their work.”

Launched in 2018, the Povaddo Panel was built to meet growing demand for research insights from individuals who shape, influence, and analyze public policy as part of their daily work. Over the past eight years, the panel has grown to nearly 5,000 public policy professionals worldwide, including over 2,000 in the United States. Many panelists are former elected officials, including former Members of Congress.

This partnership is part of a broader period of momentum for Povaddo. The company recently announced it is launching a quarterly omnibus survey among public policy professionals in the United States and Europe.

“Companies and other organizations that want to understand what public policy professionals think—whether about their brand or an issue they are facing—now have a new way of doing that. Our new omnibus survey among public policy professionals fills an important need in the research services marketplace,” said Brooke Hayes, Executive Vice President of Povaddo, who oversees the Povaddo Panel and the firm’s new omnibus research service among public policy professionals.

Additionally, Povaddo recently released select findings from its survey of public policy professionals in the U.S. and Europe regarding their attitudes towards AI. In an era when political consensus is elusive, this study finds widespread agreement within policy communities on both sides of the Atlantic that government regulation of AI should be increased.

Founded in 2009, Povaddo is recognized as a trusted advisor to top-tier organizations seeking to navigate complex issues management, strategic communications, corporate reputation, and business transformation challenges.
