从 2026 年 7 月 1 日起，一项名为 Solar Sharer Offer 的政府支持计划将为 New South Wales 、 South Australia 和 South-East Queensland 的家庭每天提供至少三小时的免费电力。该倡议旨在把中午时段太阳能带来的好处直接让利给消费者，因为这段时间往往会导致电力批发价下降。居民只需安装智能电表并通过其电力零售商选择加入，即可参加该计划，因此无论是否自有住房或屋顶是否安装太阳能板，均有资格参与。
最初提案承诺提供不设限制的免费电力，但经过公众咨询后，决定设定每天 24 kWh 的上限。制定这一上限是为了在保证零售商财务可持续性的同时，对所有电网用户保持公平。政府指出，24 kWh 足以覆盖一个五口之家的平均日用电量，因此在正常情况下大多数家庭不太可能受该上限影响。如果某户当天用电超过上限，其超出部分将按照标准日间电价计费，但不会受到额外惩罚。
对于能把高耗能活动（如洗碗机、洗衣机或泳池水泵）转移到通常在中午左右的免费时段的家庭，Solar Sharer Offer 尤为划算。节省金额取决于家庭能迁移多少用电量，年节省额估计可能从 100 美元到超过 1,000 美元不等。
对于已经安装太阳能电池板和储能电池的房主来说，该计划还能提高整体效率：即便在阴天发电量低时，用户也能在免费时段从电网免费为家用电池充电，从而在傍晚高峰时段依靠储存的免费电力。同样，电动车车主也可在这段时间为车辆充电，进一步降低用电开支。
该项目标志着能源市场的一次重要转变，把太阳能繁荣带来的利益扩展到此前受限的租户和公寓居民。准备参与的家庭应确保已安装智能电表，并熟悉主要电器的定时功能。该计划将先在部分州推出，预计未来几年其他地区会陆续跟进，可能在一些私营零售商已提供的自愿性免费电力计划基础上进一步发展。
Starting July 1, 2026, a new government-backed scheme known as the Solar Sharer Offer will provide households in New South Wales, South Australia, and South-East Queensland with at least three hours of free electricity every day. This initiative is designed to distribute the benefits of midday solar energy, which often causes wholesale electricity prices to drop, directly to consumers. To participate, residents simply need a smart meter and to opt in through their energy retailer, making the program accessible regardless of homeownership status or the presence of rooftop solar panels.
While the original proposal promised free power without limitations, a public consultation process led to the introduction of a 24 kWh daily cap. This limit was implemented to ensure the financial sustainability of the scheme for retailers while remaining fair to all grid users. The government notes that 24 kWh is sufficient to cover the total daily usage of an average five-person household, meaning the cap is unlikely to affect most residents during typical operations. If a household happens to exceed this limit, their electricity usage simply reverts to standard daytime rates without penalties.
The Solar Sharer Offer is particularly beneficial for those who can shift their high-energy activities, such as running dishwashers, washing machines, or pool pumps, into the designated free window, which typically occurs around midday. Savings estimates vary based on how much energy usage a household can relocate, with potential annual savings ranging from $100 to over $1,000 for those who maximize their usage during these hours.
For homeowners already utilizing solar panels and battery storage, this scheme adds an extra layer of efficiency. Users can charge their home batteries from the grid at no cost during the free window, even on overcast days when solar generation is low, allowing them to rely on stored, free energy during expensive peak evening hours. Similarly, electric vehicle owners can use this period to charge their cars, further reducing their overall energy expenses.
The program represents a major shift in the energy market by extending the advantages of the solar boom to renters and apartment dwellers who previously faced barriers to entry. To prepare, interested households should ensure they have a smart meter installed and familiarize themselves with the scheduling capabilities of their major appliances. While the scheme is launching in select states first, other regions are expected to follow in the coming years, potentially building on the existing voluntary free-power plans already offered by some private retailers.

• Australia 正在强制要求 NSW 、 Queensland 和 South Australia 的能源零售商，从 2026 年年中起至少提供一款每天包含三小时"免费"用电时段且上限为 24 kWh 的电价方案。
• 这些"免费"能源计划并非对所有家庭都有利：通常伴随更高的固定供应费，并在免费时段以外收取更高电价以补偿供应商成本。
• 拥有屋顶太阳能、家用电池和电动汽车的家庭最能受益：他们可以在免费时段为储能系统充电，并将热水加热或电动汽车充电等高耗能活动安排在该时段进行。
• 在补贴和高电价的推动下，Australia 的住宅太阳能和家用电池普及率激增，实际上形成了一个去中心化的电力系统，有助于缓解夜间高峰需求。
• 在嵌入式网络安排下，公寓居民和租户经常被结构性排斥：物业或大楼管理方与供应商签订了独家且不透明的能源合约，剥夺了居民更换供应商或自行安装独立太阳能系统的权利。
• 尽管像 Snowy 2.0 这样的电网级储能项目存在严重成本超支和施工延期，但较小的家用电池和分布式太阳能装置已被证明更具成本效益且部署更快。
• 投资电池的经济逻辑正在改变，因为政府强制的免费用电时段和负批发电价正在激励屋主自掏腰包投资用于电网稳定的储能。
• 批评者认为，政府对电池的补贴实际上是一种累退性的财富转移，把纳税人的钱输送给那些已有可支配收入、能够投资昂贵设备的屋主，而不是直接用于缓解能源贫困。
• "反弹效应"表明，免费的用电时段可能无意中鼓励总体用电增加；尽管支持者认为，将用电转移到供应过剩的时段对于管理电网频率和避免削峰停电至关重要。
• 诸如 Home Assistant 及智能家电等技术解决方案允许用户自动调整用电以匹配实时电价和免费时段，从而进一步提升分布式能源资源的投资回报。
Australia 的能源市场正经历重大转型。屋顶太阳能的高渗透率压低了白天电价，产生了挑战传统电网经济学的盈余时段。尽管政府强制推行的"免费"用电计划为家庭转移用电提供了强烈激励，但这些政策也凸显出能通过电池和太阳能消除电费的有房家庭，与被嵌入式网络限制、无法选择供应商或安装独立系统的租户之间日益扩大的鸿沟。这场讨论反映了市场机制效率与政府主导干预之间的更广泛紧张：政府既要管理老化的电网并推进向可再生能源的转型，又要避免将不公平负担强加给那些无法参与投资的人。 • Australia is mandating that energy retailers in NSW, Queensland, and South Australia offer at least one plan featuring three hours of "free" electricity per day, capped at 24kWh, starting in mid-2026.
• These "free" energy plans are not universally applicable to every household, as they typically feature higher supply charges and elevated usage rates outside the free window to offset the provider's costs.
• Households with rooftop solar, home batteries, and electric vehicles are best positioned to capitalize on these offers, using the free window to charge storage systems and perform energy-intensive tasks like heating or EV charging.
• Residential solar and battery adoption in Australia has surged due to subsidies and high electricity costs, effectively creating a decentralized grid that helps flatten peak evening demand.
• Apartment dwellers and renters often face structural exclusion from these benefits due to "embedded network" arrangements, where building managers sign exclusive, opaque energy contracts that deny residents the ability to switch providers or install independent solar systems.
• While grid-scale storage projects like Snowy 2.0 face massive cost blowouts and construction delays, smaller consumer-level batteries and distributed solar installations have proven to be more cost-effective and faster to deploy.
• The economic logic for battery adoption is shifting, as government-mandated free energy windows and negative wholesale pricing incentivize homeowners to invest their own capital into grid-stabilizing storage.
• Critics argue that government subsidies for batteries effectively function as regressive wealth transfers, funneling taxpayer money toward homeowners who already have the disposable income to invest in expensive hardware, rather than solving energy poverty directly.
• The "rebound effect" suggests that free energy may inadvertently encourage higher total consumption, though proponents argue that shifting usage to times of oversupply is critical for managing grid frequency and preventing curtailment.
• Technological solutions like Home Assistant and smart-enabled appliances allow users to automate their energy consumption to match real-time pricing and free windows, further increasing the return on investment for distributed energy resources.
The Australian energy market is currently undergoing a significant transition as the high penetration of rooftop solar drives down mid-day electricity prices, leading to periods of surplus that challenge traditional grid economics. While government-mandated "free" energy plans offer a compelling incentive for households to shift their consumption, these policies highlight a widening divide between property-owning households, who can leverage batteries and solar to eliminate their bills, and renters trapped in restrictive embedded networks. The discussion reflects a broader tension between the efficiency of market-based mechanisms and the necessity of state-led interventions to manage an aging power grid while ensuring that the transition to renewables does not unfairly burden those without the capital to participate.
