From Ireland this week the regulatory drum kept beating: CRU published a minded-to decision on offshore wind grid compensation and confirmed a landmark reform scrapping unfair grid charges on battery storage from October — two moves with real implications for where Ireland’s electricity system goes next. The EU, meanwhile, doubled down on building energy performance, launching a Better Homes call and publishing a comprehensive EPBD briefing that spells out exactly what non-residential operators face by 2030 and 2033. In Britain, DESNZ had one of its busier weeks — public-sector decarbonisation data, a consumer-protection overhaul for home upgrades, and a plug-in solar push all landed together. Further afield, the signals are about grid stress: US regulators ordered reforms on data-centre connections, and Ember’s India analysis showed what happens when storage deployment lags renewable growth.

CRU Consultations

CRU opens offshore wind GoA consultation and a new gas pipeline application in Kilkenny

CRU had two notable publications this week. Its Minded to Decision paper (CRU/26/97) sets out the framework for the Phase 1 offshore wind Guarantee of Availability policy — the mechanism that will compensate developers for losses during unplanned transmission outages once assets transfer to EirGrid post-2030, covering a 20-year period after ORESS 1 support ends; the consultation runs until 4 September, with a final decision expected Q4 2026. Separately, CRU opened a public consultation (17 Jun – 17 Jul) on Gas Networks Ireland’s Section 39A application for a new 1,280m underground gas distribution pipeline serving Castle Gypsum Ltd.’s calcination and drying facility in Co. Kilkenny, with construction slated for Q4 2026 pending approval.

What it means: The GoA framework is upstream policy that shapes investor confidence in offshore wind — and ultimately the cost and availability of clean electricity on the Irish grid over the 2030s. The Kilkenny pipeline is a localised industrial project with no direct implications for most operators, but it signals that new industrial gas connections are still moving through standard regulatory channels.

EPA: Irish water quality stalled in 2025 despite localised gains

The EPA’s 2025 Water Quality Indicators Report, published on 17 June, found no meaningful overall improvement: only 54% of rivers and lakes achieved good or better biological quality, with excess nitrogen and phosphorus from agriculture and wastewater remaining the dominant drivers. Some localised progress — notably in Wexford’s Ballyteigue-Bannow catchment — was offset by declines elsewhere, and the EPA called for accelerated action to meet Water Framework Directive objectives.

What it means: This is primarily a land-use and wastewater story rather than an energy one, but operators in food production, agri-processing, or any sector with a water-use or discharge footprint should note that regulatory pressure on water quality is heading in one direction only — tighter, faster.

Wind farms put €75m into local authority coffers; bursary backs next-gen renewables talent

Wind Energy Ireland’s analysis (compiled by Halpin’s) shows wind farms contributed €74.87 million in commercial rates to Irish local authorities in March 2026, up 8% year-on-year — Offaly now derives almost 31% of its commercial rates income from wind energy, and nine counties exceed 10%. In the same week, the 2026 Niamh Burke Renewable Energy Bursary recipients were announced: Sean Loewen (University of Galway, Energy Systems Engineering, high-renewable integration) and Sean Gahan (TU Dublin, Mechanical Engineering, green hydrogen from curtailed renewables) each receive €10,000, funded by Arthur Cox.

What it means: The rates figures underline how embedded wind has become in rural Ireland’s public finances — context worth having when local planning or community consultations arise. The bursary awards are a small but telling signal that the sector is investing in workforce pipeline, particularly around integration and hydrogen, which are the next bottlenecks.

Energy Storage Ireland News

CRU confirms battery storage to lose punitive grid charges from October

CRU has confirmed it will remove Demand Transmission Use of System (D-TUoS) charges on battery storage from 1 October 2026, replacing them with Generation TUoS charges on the same basis as wind and solar. The charge being removed had added up to €30/MWh to the cost of charging storage — a significant deterrent to efficient siting of assets. All but one of the 17 consultation respondents supported the change. The decision is described as an interim measure pending a wider electricity network tariff review.

What it means: For any operator weighing up behind-the-meter battery storage — or evaluating flexibility services — October’s change materially improves the economics. It won’t transform project appraisals overnight, but it removes a structural distortion that was actively discouraging storage deployment at exactly the moment the grid needs it most.

European Commission, DG Energy

Commission pushes building renovation hard: Better Homes call, EPBD briefing, and a new biomethane marketplace

DG Energy had a full week on buildings and clean gas. It launched a call for expressions of interest under the Better Homes Partnerships initiative — part of the Citizen’s Energy Package — seeking concrete renovation projects, replicable solutions, and innovative financing models from public authorities, housing providers, financial institutions, and others; the deadline is 21 August 2026. Alongside it, the Commission published a detailed briefing on the revised Energy Performance of Buildings Directive, which requires the worst-performing 16% of non-residential buildings to be upgraded by 2030 and 26% by 2033, targets a 16% average reduction in residential energy use by 2030, and makes zero-emission performance the standard for all new buildings from 2030 (public buildings from 2028). Separately, the Commission launched the Biomethane Mechanism — a free voluntary platform under the EU Energy and Raw Materials Platform to connect producers, buyers, and investors — with the first matching round scheduled for September 2026.

What it means: The EPBD briefing is the one to print out and share with your board or landlord: the 2030 non-residential deadline is less than four years away, and the 16%-then-26% sequencing means buildings that are borderline today are likely in scope. The Better Homes call is primarily aimed at housing providers and public bodies, but the financing models it surfaces will likely inform what SEAI programmes look like in the next funding cycle.

DESNZ: decarbonisation data, home-upgrade consumer reforms, plug-in solar, and AI grid demand

DESNZ published delivery data for all six phases of the Public Sector Decarbonisation Scheme, covering low-carbon heating and efficiency upgrades from September 2020 through Phase 4; figures are provisional pending project finalisation. It also opened a consultation (closing 10 September) on overhauling consumer protection for home upgrade schemes under the Warm Homes Plan — prompted by stark failures in existing programmes, including a finding that 98% of external wall insulation under ECO4 had major defects; reforms would introduce a single government-accountable protection service, a public installer register, and an ombudsman from 2028. On solar, DESNZ consulted on allowing plug-in solar panels to be sold and self-installed by households without professional installation, backed by a safety study confirming that devices operating within 400–800W export limits behave safely within domestic circuits — major retailers including B&Q, Currys, and Lidl have already committed to stocking them. Finally, the department published minutes from four AI Energy Council sessions (April 2025–April 2026), revealing that UK data-centre electricity demand forecasts of 6–10 GW sit against a 125 GW grid connection backlog, with ministers, Ofgem, and tech firms including Google, AWS, and Microsoft working through how AI growth zones and voluntary flexibility mechanisms might ease the pressure.

What it means: None of this binds Irish operators directly, but three threads are worth watching: the PSDS data provides a useful benchmark for what public-sector retrofit programmes deliver at scale; the consumer-protection reforms signal the direction SEAI may move if installer quality issues emerge here; and the AI grid-demand figures — UK data centres potentially tripling demand by 2030–2035 — are a preview of the grid-planning headache that will land on EirGrid’s desk as Irish data-centre capacity keeps growing.

Carbon Brief

Carbon Brief: Bonn gridlock, China’s provincial climate plans, AC efficiency in India, and carbon removal

Carbon Brief covered a lot of ground this week. The June UN climate talks in Bonn closed in what its briefing described as ‘gridlock’, with few tangible outcomes from the two-week session. A detailed Q&A unpacked China’s 15th five-year plans at provincial level, reviewing commitments on renewables, coal phase-out, and efficiency targets — while noting significant variation in provincial ambition and uncertain enforcement. Analysis of India’s air-conditioning market suggested that replacing existing stock with higher-efficiency units could save Indian households ₹69 billion ($724m) annually. And a report from a Milan conference of over 260 researchers concluded that carbon removal technologies — covering direct air capture, bioenergy with CCS, and soil sequestration — need a major scale-up to keep 1.5°C within reach.

What it means: Bonn gridlock is a background signal rather than an immediate operational trigger, but it does suggest the international architecture underpinning carbon markets and future EU carbon border mechanisms is moving slowly — worth bearing in mind for any business modelling long-term carbon costs. The India AC efficiency analysis is a reminder that cooling demand is rising in Irish commercial buildings too, and the efficiency of the equipment you install now will matter for a decade.

Inside Climate News

FERC orders data-centre grid reforms; sponge cities face storm limits; a journalism loss

Further afield, Inside Climate News covered three distinct stories this week. US regulator FERC ordered six major grid operators to propose reforms within 60 days on how data centres connect to the electricity grid, amid concerns that hyperscale buildouts are raising regional electricity prices and risking cost-shifting to residential ratepayers; grid operators must also report within 30 days on generation adequacy for large new loads. A separate piece examined the limits of ‘Sponge Cities’ — urban green-infrastructure systems designed to absorb flooding — finding that climate-driven shifts toward fewer, heavier rainfall events may overwhelm the absorptive capacity these systems were designed for, even as they remain superior to conventional impervious surfaces. The outlet also marked the death of environmental journalist James Bruggers, 68, whose four decades of investigative reporting on toxic air and plastics drove measurable real-world change.

What it means: The FERC data-centre orders are the US equivalent of the conversation EirGrid and CRU are quietly having about Irish data-centre demand — and the precedent of requiring grid operators to formally stress-test adequacy before approving large new loads could easily migrate into European regulatory thinking. The sponge-city findings are a useful prompt for any operator investing in SUDS or green-roof schemes: design to a more extreme rainfall envelope than historical averages suggest.

Ember: India’s renewable curtailment problem shows what happens when storage lags

Ember’s analysis of India’s grid found that solar and wind reached 41% of midday generation in March 2026 — but coal’s inflexibility at minimum technical load forced 2.1 TWh of curtailment in FY 2025–26, worth ₹629 crore. Around 10 GWh of battery storage could prevent most of that curtailment by absorbing the midday surplus, yet restrictive connectivity rules currently block BESS from grid-charging during peak solar periods, delaying the very deployment the grid needs.

What it means: This is India’s problem today, but it is Ireland’s problem in outline: as wind and solar penetration rises, the value of flexible storage — and the cost of rules that discourage it — compounds quickly. CRU’s D-TUoS decision this week is a step in the right direction, but Ember’s numbers illustrate how much is at stake if regulatory reform doesn’t keep pace with renewable build-out.

Volts (David Roberts)

General Motors bets on vehicle-to-grid as a home energy play

David Roberts reports that General Motors is entering the home energy market by aggregating its EV fleet’s vehicle-to-grid (V2G) and vehicle-to-home (V2H) capabilities into a distributed virtual power plant, monetising charging flexibility for utilities and homeowners during peak demand.

What it means: V2G as a mainstream utility product is still a US-market development at this stage, but the direction of travel is clear: EVs are increasingly being designed as grid assets, not just transport assets — a dynamic that will eventually reshape how Irish commercial fleet operators think about their charging infrastructure and demand-flexibility contracts.

If there’s one document to read before the summer break, it’s the Commission’s EPBD buildings briefing — the 2030 non-residential deadline is closer than it looks, and the buildings that need to act first are exactly the ones that haven’t started yet.
