Zambia, Africa's largest producer of copper, has suffered chronic power shortages and breakdowns over the past few decades. In the last days of April, it was reported that the country's National Tender Board was finalizing plans to offer an international tender for the development of the Kafue Gorge hydropower station.

A day later, it was announced that two generators had collapsed at the power station, putting further pressure on the load-shedding program that the Zambia Electricity Supply Corporation (Zesco) is already implementing.

A company spokesperson said that the generators would be up again in two days and that power imports from the Democratic Republic of Congo had not been received for days because of transmission faults, causing the to machines to kick out. Maintenance on the other two generators at Kafue had been carried out 10 days previously.

The new tender is aimed at improving capacity and generating efficiency in the country, which has the capacity to produce 1,600 megawatts (MW) but only produces 1,000 MW because of the lack of investment in the maintenance and optimization of the plant. Kafue has the potential to output 750 MW, and it is estimated that $1 billion investment is required to develop the plant to that level and assist in the increase of power to the country's copper mines that are forecast to produce a possible 1 million tons of copper by 2010.

Some mines are reported have offered six future investments in the development project.

Zesco and Tata Africa Holdings of South Africa (Mumbai/Johannesburg) have issued an international tender for a $230 million power station. The partners have formed Itezhi-Tezhi Power Corporation (ITPC) to manage the construction of the 120 MW project, which is scheduled to be commissioned in June 2012. Bids are invited for the design, supply, construction and commissioning of the project.

Road, housing and water and sanitation contracts will be scheduled for completion by March 2009. ITPC will seek loans from financial institutions to meet part of the costs.

A national output of 2,500 MW will be needed by 2013 to cope with the requirements of the growing mining industry. Zesco is in negotiation with Japanese, Indian and international financial institution to raise $600 million for system upgrades and the ITPC development.

Ontario Teachers Pension Plan agrees to acquire a 25% stake in SSEN Transmission

Ontario Teachers SSEN Transmission Investment advances UK renewable energy, with a 25% minority stake in SSE plc's electricity transmission network, backing offshore wind, grid expansion, and Net Zero 2050 goals across Scotland and UK.

 

Key Points

A 25% stake by Ontario Teachers in SSE's SSEN Transmission to fund UK grid upgrades and accelerate renewables.

✅ £1,465m cash for 25% minority stake in SSEN Transmission

✅ Supports offshore wind, grid expansion, and Net Zero targets

✅ Partnering SSE plc to deliver clean, affordable power in the UK

 

Ontario Teachers’ Pension Plan Board (‘Ontario Teachers’) has reached an agreement with Scotland-based energy provider SSE plc (‘SSE’) to acquire a 25% minority stake in its electricity transmission network business, SSEN Transmission, to provide clean, affordable renewable energy to millions of homes and businesses across the UK, reflecting how clean-energy generation powers both the economy and the environment.

The transaction is based on an effective economic date of 31 March 2022, and total cash proceeds of £1,465m for the 25% stake are expected at completion. The transaction is expected to complete shortly.

Measures such as Ontario's 2021 electricity rate reductions have aimed to ease costs for businesses, informing broader discussions on affordability.

SSEN Transmission, which operates under its licenced entity, Scottish Hydro Electric Transmission plc, transports electricity generated from renewable resources – including onshore and offshore wind and hydro – from the north of Scotland across more than a quarter of the UK land mass amid scrutiny of UK electricity and gas networks profits under the regulatory regime. The investment by Ontario Teachers’ will help support the UK Government’s Net Zero 2050 targets, including the delivery of 50GW of offshore wind capacity by 2030.

Charles Thomazi, Senior Managing Director, Head of EMEA Infrastructure & Natural Resources, from Ontario Teachers’ said, noting that in Canada decisions like the OEB decision on Hydro One's T&D rates guide utility planning:

“SSEN Transmission is one of Europe’s fastest growing transmission networks. Its network stretches across some of the most challenging terrain in Scotland – from the North Sea and across the Highlands – to deliver safe, reliable, renewable energy to demand centres across the UK.

We’re delighted to partner again with SSE and are committed to supporting the growth of its network and the vital role it plays in the UK’s green energy revolution.”

Investor views on regulated utilities can diverge, as illustrated by analyses of Hydro One's investment outlook that weigh uncertainties and risk factors.

Rob McDonald, Managing Director of SSEN Transmission, said:

“With the north of Scotland home to the UK’s greatest resources of renewable electricity we have a critical role to play in helping deliver the UK and Scottish Governments net zero commitments.  Our investments will also be key to securing the UK’s future energy independence through enabling the deployment of homegrown, affordable, low carbon power.

“With significant growth forecast in transmission, bringing in Ontario Teachers’ as a minority stake partner will help fund our ambitious investment plans as we continue to deliver a network for net zero emissions across the north of Scotland.” 

Ontario Teachers’ Infrastructure & Natural Resources group invests in electricity infrastructure worldwide to accelerate the energy transition with current investments including Caruna, Finland’s largest electricity distributor, Evoltz, a leading electricity transmission platform in Brazil, and Spark Infrastructure, which invests in essential energy infrastructure in Australia to serve over 5 million homes and businesses.

In Ontario, distribution consolidation has included the sale of Peterborough Distribution to Hydro One for $105 million, illustrating ongoing sector realignment.

Ontario Launches Peak Perks Program

Ontario Peak Perks Program boosts energy efficiency with smart thermostats, demand response, and incentives, reducing peak demand, electricity costs, and emissions while supporting grid reliability and Save on Energy initiatives across Ontario businesses and homes.

 

Key Points

A demand response initiative offering incentives via smart thermostats to cut peak electricity use and lower costs

✅ $75 sign-up, $20 yearly enrollment incentive

✅ Up to 10 summer temperature events; opt-out anytime

✅ Expanded retrofits, greenhouse support, grid savings

 

The Ontario government is launching the new Peak Perks program to help families save money by conserving energy, building on bill support during COVID-19 initiatives as part of the government’s $342 million expansion of Ontario’s energy-efficiency programs that will reduce demands on the provincial grid. The government is also launching three new and enhanced programs for businesses, municipalities, and other institutions, including targeted support for greenhouse growers in Southwest Ontario.

“Our government is giving families more ways to lower their energy bills with new energy-efficiency programs like Peak Perks and ultra-low overnight rates available to consumers, which will provide families a $75 financial incentive this year in exchange for lowering their energy use at peak times during the summer,” said Todd Smith, Minister of Energy. “The new programs launched today will also help meet the province’s emerging electricity system needs by providing annual electricity savings equivalent to powering approximately 130,000 homes every year and, alongside electricity cost allocation discussions, reduce costs for consumers by over $650 million by 2025.”

The new Peak Perks program provides a financial incentive for residential customers who are willing to conserve energy and reduce their air conditioning at peak times and have an eligible smart thermostat connected to a central air conditioning system or heat pump unit. Participants will receive $75 for enrolling this year, as well as $20 for each year they stay enrolled in the program starting in 2024.

Residential customers can participate in Peak Perks by enrolling and giving their thermostat manufacturer secure access to their thermostat. Participants will be notified when one of the maximum 10 annual temperature change events occurs directly by their thermostat manufacturer on their mobile app and on their thermostat. Peak Perks has been designed to ensure participants are always in control and customers can opt-out of any temperature change event without impacting their incentive.

The Peak Perks program will be available starting in June. Interested customers can visit SaveOnEnergy.ca/PeakPerks today to sign-up for the program waitlist and receive an email notice with information on how to enroll.

In addition to the financial incentive provided by Peak Perks, reducing electricity use during peak demand hours in the summer months helps customers to lower their monthly electricity bills, and measures such as a temporary off-peak rate freeze have complemented these efforts, as these periods tend to be associated with the highest costs for power. Lowering demand during peak periods also allows the province to reduce electricity sector emissions, by reducing the need for electricity generation facilities that only run at times of peak demand such as natural gas.

Ontario has also launched three new and enhanced programs, including an expanded custom Retrofit program for business, municipalities and other institutions, and industrial electricity rate relief initiatives, targeted support for greenhouse growers in Southwest Ontario, as well enhancements to the existing Local Initiatives Program. The expanded Retrofit program alone will feature over $200 million in dedicated funding to support the new custom energy-efficiency retrofit project stream, that will cover up to 50 percent of the cost of approved projects.

These new and expanded energy-efficiency programs are expected to have a strong impact in Southwest Ontario, with regional peak demand savings of 225 megawatts (MW). This, together with the Ontario-Quebec energy swap agreement, will provide additional capacity for the region and support growing economic development. The overall savings from this energy-efficiency programming will result in an estimated three million tonnes of greenhouse gas emission reductions over its lifetime - the equivalent to taking more than 600,000 vehicles off the road for one year.

“Thanks to energy efficiency efforts over the past 15 years, demand for electricity is today about 12 per cent lower than it otherwise would be,” said Lesley Gallinger, President and CEO, of the Independent Electricity System Operator, Ontario’s grid operator and provider of Save on Energy programs to home and business consumers. “Conservation is a valuable and cost-effective resource that supports system reliability and helps drive economic development as we strive towards compliance with clean electricity regulations for a decarbonized electricity grid.”

Costa Rica hits record electricity generation from 99% renewable sources

Costa Rica Renewable Energy Record highlights 99.99% clean power in May 2019, driven by hydropower, wind, solar, geothermal, and biomass, enabling ICE REM electricity exports and reduced rates from optimized generation totaling 984.19 GWh.

 

Key Points

May 2019 benchmark: Costa Rica generated 99.99% of 984.19 GWh from renewables, shifting from imports to regional exports.

✅ 99.99% renewable share across hydro, wind, solar, geothermal, biomass

✅ 984.19 GWh generated; ICE suspended imports and exported via REM

✅ Geothermal output increased to offset dry-season hydropower variability

 

During the whole month of May 2019, Costa Rica generated a total of 984.19 gigawatt hours of electricity, the highest in the country’s history. What makes this feat even more impressive is the fact that 99.99% of this energy came from a portfolio of renewable sources such as hydropower, wind, biomass, solar, and geothermal.

With such a high generation rate, the state power company Instituto Costariccense de Electricidad (ICE) were able to suspend energy imports from the first week of May and shifted to exports, while U.S. renewable electricity surpassed coal in 2022 domestically. To date, the power company continues to sell electricity to the Regional Electricity Market (REM) which generates revenues and is likely to reduce local electricity rates, a trend echoed in places like Idaho where a vast majority of electricity comes from renewables.

The record-breaking power generation was made possible by optimization of the country’s renewable sources, much as U.S. wind capacity surpassed hydro capacity at the end of 2016 to reshape portfolios. As the period coincided with the tail end of the dry season, the geothermal quota had to be increased.

Costa Rica remains a leader in renewable power generation, whereas U.S. wind generation has become the most-used renewable source in recent years. In 2015, more than 98% of the country’s electrical generation came from renewable sources, while U.S. renewables hit a record 28% in April in one recent benchmark. Through the years, this figure has remained fairly constant despite dry bouts caused by the El Niño phenomenon, and U.S. solar generation also continued to rise.

Newsom Vetoes Bill to Codify Load Flexibility

California Governor Gavin Newsom vetoed a bill aimed at expanding load flexibility in state grid planning, citing conflicts with California’s resource adequacy framework and concerns over grid reliability and energy planning uncertainty.

 

Why has Newsom vetoed the Bill to Codify Load Flexibility?

Governor Gavin Newsom’s veto blocks legislation that would have required the California Energy Commission to incorporate load flexibility into the state’s energy planning and policy framework, a move that has stirred debate across the clean energy sector.

✅ Argues the bill conflicts with California’s existing Resource Adequacy system

✅ Draws backlash from clean energy and grid modernization advocates

✅ Exposes ongoing tension over how to manage renewable integration and demand response

 

California Governor Gavin Newsom has vetoed Assembly Bill 44, which would have required the California Energy Commission to evaluate and incorporate load management mechanisms into the state’s energy planning process. The move drew criticism from clean energy advocates who say it undermines efforts to strengthen grid reliability and reduce costs.

The bill directed the commission to adopt “upfront technical requirements and load modification protocols” that would allow load-serving entities to adjust their electrical demand forecasts. Proponents viewed this as a way to modernize California’s grid management, and to explore a revamp of electricity rates to help clean the grid, making it more responsive to demand fluctuations and renewable energy variability.

In his veto statement, Newsom said the bill was incompatible with existing energy planning frameworks, even as a looming electricity shortage remains a concern. “While I support expanding electric load flexibility, this bill does not align with the California Public Utility Commission’s Resource Adequacy framework,” he said. “As a result, the requirements of this bill would not improve electric grid reliability planning and could create uncertainty around energy resource planning and procurement processes.”

Newsom’s decision comes shortly after he signed a broad package of energy legislation that set the stage for a regional Western electricity market and extended the state’s cap-and-trade program. However, that legislative package did not include continued funding for several key grid reliability programs — including what advocates have called the world’s largest virtual power plant, a distributed network of connected devices that can balance electricity demand in real time.

Clean energy supporters saw AB 44 as a crucial step toward integrating these distributed energy resources into long-term grid planning. “With Assembly Bill 44 being vetoed, the state has missed a huge opportunity to advance common-sense policy that would have lowered costs, strengthened the grid, and unlocked the full potential of advanced energy,” said Edson Perez, California lead at Advanced Energy United.

Perez added that the setback increases pressure on lawmakers to take stronger action in the next legislative session. “The pressure is on next session to ensure that California is using all tools in its policy toolbox to build critically needed infrastructure, strengthen the grid, and bring costs down,” he said.

California’s growing use of demand response programs and virtual power plants has been central to its strategy for managing grid stress during heat waves and wildfire seasons. These systems allow utilities and customers to temporarily reduce or shift energy use, helping to prevent blackouts and reduce the need for fossil-fuel peaker plants during peak demand.

A recent report by the Brattle Group found that California’s taxpayer-funded virtual power plant could save ratepayers $206 million between 2025 and 2028 while reducing reliance on gas generation. The study, commissioned by Sunrun and Tesla Energy, highlighted the potential for flexible load management to improve both grid reliability and reduce costs, even as regulators weigh whether the state needs more power plants to ensure reliability.

Despite these findings, Newsom’s veto signals continued tension between state policymakers and clean energy advocates over how best to modernize California’s power grid. While the governor has prioritized large-scale renewable development and regional market integration, critics argue that California’s climate policy choices risk exacerbating reliability challenges and that failing to codify load flexibility could slow progress toward a more adaptive, resilient, and affordable clean energy future.

Two new BC generating stations officially commissioned

BC Hydro Site C and Clean Energy Policy shapes B.C.'s power mix, affecting run-of-river hydro, net metering for rooftop solar, independent power producers, and surplus capacity forecasts tied to LNG Canada demand.

 

Key Points

BC Hydro's strategy centers on Site C, limiting new run-of-river projects and tightening net metering amid surplus power

✅ Site C adds long-term capacity with lower projected rates.

✅ Run-of-river IPP growth paused amid surplus forecasts.

✅ Net metering limits deter oversized rooftop solar.

 

Innergex Renewable Energy Inc. is celebrating the official commissioning today of what may be the last large run-of-river hydro project in B.C. for years to come.

The project – two new generating stations on the Upper Lillooet River and Boulder Creek in the Pemberton Valley – actually began producing power in 2017, but the official commissioning was delayed until Friday September 14.

Innergex, which earlier this year bought out Vancouver’s Alterra Power, invested $491 million in the two run-of-river hydro-electric projects, which have a generating capacity of 106 megawatts of power. The project has the generating capacity to power 39,000 homes.

The commissioning happened to coincide with an address by BC Hydro CEO Chris O’Riley to the Greater Vancouver Board of Trade Friday, in which he provided an update on the progress of the $10.7-billion Site C dam project.

That project has put an end, for the foreseeable future, of any major new run-of-river projects like the Innergex project in Pemberton.

BC Hydro expects the new dam to produce a surplus of power when it is commissioned in November 2024, so no new clean energy power calls are expected for years to come.

Independent power producers aren’t the only ones who have seen a decline in opportunities to make money in B.C. providing renewable power, as the Siwash Creek project shows. So will homeowners who over-build their own solar power systems, in an attempt to make money from power sales.

There are about 1,300 homeowners in B.C. with rooftop solar systems, and when they produce surplus power, they can sell it to BC Hydro.

BC Hydro is amending the net metering program to discourage homeowners from over-building. In some cases, some howeowners have been generating 40% to 50% more power than they need.

“We were getting installations that were massively over-sized for their load, and selling this big quantity of power to us,” O’Riley said. “And that was never the idea of the program.”

Going forward, BC Hydro plans to place limits on how much power a homeowner can sell to BC Hydro.

BC Hydro has been criticized for building Site C when the demand for power has been generally flat, and reliance on out-of-province electricity has drawn scrutiny. But O’Riley said the dam isn’t being built for today’s generation, but the next.

“We’re not building Site C for today,” he said. “We have an energy surplus for the short term. We’re not even building it for 2024. We’re building it for the next 100 years.”

O’Riley acknowledged Site C dam has been a contentious and “extremely challenging” project. It has faced numerous court challenges, a late-stage review by the BC Utilities Commission, cost overruns, geotechnical problems and a dispute with the main contractors.

In a separate case, the province was ordered to pay $10 million over the denial of a Squamish power project, highlighting broader legal risk.

But those issues have been resolved, O’Riley said, and the project is back on track with a new construction schedule.

“As we move forward, we have a responsibility to deliver a project on time and against the new revised budget, and I’m confident the changes we’ve made are set up to do that,” O’Riley said.

Currently, there are about 3,300 workers employed on the dam project.

Despite criticisms that BC Hydro is investing in a legacy mega-project at a time when cost of wind and solar have been falling, O’Riley insisted that Site C was the best and lowest cost option.

“First, it’s the lowest cost option,” he said. “We expect over the first 20 years of Site C’s operating life, our customers will see rates 7% to 10% below what it would otherwise be using the alternatives.”

BC Hydro missed a critical window to divert the Peace River, something that can only be done in September, during lower river flows. That added a full year’s delay to the project.

O’Riley said BC Hydro had built in a one-year contingency into the project, so he expects the project can still be completed by 2024 – the original in-service target date. But the delay will add more than $2 billion to the last budget estimate, boosting the estimated capital cost from $8.3 billion to $10.7 billion.

Meeting the 2024 in-service target date could be important, if Royal Dutch Shell and its consortium partners make a final investment decision this year on the $40 billion LNG Canada project.

That project also has a completion target date of 2024, and would be a major new industrial customer with a substantial power draw for operations.

“If they make a decision to go forward, they will be a very big customer of BC Hydro,” O’Riley told Business in Vancouver. “They would be in our top three or four biggest customers.”

Congressional Democrats push FERC to act on aggregated DERs

FERC DER Aggregation advances debates over distributed energy resources as Congress presses action on Order 841, grid resilience, and wholesale market access, including rooftop solar, storage, and virtual power plant participation across PJM and ISO-NE.

 

Key Points

FERC DER Aggregation enables grouped distributed resources to join wholesale markets, providing capacity and flexibility.

✅ Opens wholesale market access for aggregated DER portfolios

✅ Aligns with Order 841, storage, and grid resilience goals

✅ Raises jurisdictional questions between FERC and state regulators

 

The Monday letter from Congressional Democrats illustrates growing frustration in Washington over the lack of FERC action on multiple power sector issues, including the aging U.S. grid and related challenges.

Last May, after the FERC technical conference, 16 Democratic Senators wrote to then-Chairman Kevin McIntyre urging him to develop guidance for grid operators on aggregated DERs.

In July, McIntyre responded, saying that FERC was "diligently reviewing the record," but the commission has taken no action since.

Since then, "DER adoption and renewable energy aggregation have continued to grow," House and Senate lawmakers wrote in their identical Monday letters, "driven not only by state and federal policies, but consumer interest in choosing cost-competitive technologies such as rooftop solar, smart thermostats and customer-sited energy generation and storage, reflecting key utility trends in the sector."

The lawmakers wrote they were "encouraged" by FERC Chairman Neil Chatterjee's comments in June 2018, writing that he "specifically cited the role DERs will play in our continued grid transition."

In that speech at the S&P Global Platts 2018 Transmission Planning and Development Conference, Chatterjee noted "growing interest" in non-transmission alternatives, including "DERs and storage."

"How the Commission treats filings associated with those first-of-kind projects could prove an important factor in investors’ assessments of whether similar non-traditional projects are bankable or not — and more broadly signal whether FERC is open to innovation in the transmission sector,” he said.

In addition to the DER order and rehearing decision on Order 841, FERC has multiple other power sector initiatives that have not seen official action in months, even as major changes to electricity pricing are debated by stakeholders.

The highest profile is its open proceeding on grid resilience, set up last January after FERC rejected a coal and nuclear bailout proposal from the Department of Energy. In October, the CEO of the PJM Interconnection, the nation’s largest wholesale power market, urged FERC to issue a final order in the docket, calling for "leadership" from the commission.

Chatterjee, however, has not indicated when FERC could decide on the case. In December, Commissioner Rich Glick told a Washington audience he is "not entirely sure where the chairman wants to go with that proceeding yet."

Outside of resilience, FERC also has open reviews of both its pipeline certificate policy and implementation of the Public Utilities Regulatory Policy Act, a key law supporting renewable energy. McIntrye set those reviews in motion during his tenure as chairman, but after his death in January the timing of both remains unclear.

In recent months, Chatterjee has also delayed FERC votes on major export facilities for liquefied natural gas and a political spending case involving PJM after impasses between Republicans and Democrats on FERC.

Two members from each party currently sit on the commission. That allows Democrats to deadlock commission votes on natural gas facilities and other issues — a partisan divide on display this week when they clashed with the chairman over offshore wind.

As the commission considers final guidance on DERs, the boundaries of federal jurisdiction are likely to be a key issue. At the technical conference, states from the Midcontinent ISO argued FERC should allow them to choose whether to let aggregated DERs participate in retail and wholesale markets. Other states argued the value proposition of distributed resources may rely on that sort of dual participation.

Despite the lack of action from FERC, some grid operators are moving forward with aggregated distributed resources in New England market reform efforts and elsewhere, demonstrating momentum. Last week, a residential solar-plus-storage aggregation cleared the ISO-NE capacity auction for the first time, committing to provide 20 MW of capacity beginning in 2022.

On the Senate side, Sens. Sheldon Whitehouse, R.I., and Ed Markey, Mass., led the letter to FERC. In the House, Reps. Peter Welch, Vt., and Mike Levin, Calif., led the signatories.
