The AEMC today released its Unlocking CER benefits through flexible trading draft determination. This includes three main areas of reform: 🏭 Large customers - Allowing large customers to have separate market settlement points (different retailers) for different loads behind a connection without needing to establish an embedded network. enX considers this also provides a good alternative to demand response aggregation under the wholesale demand response mechanism. Flexible loads can now more easily be settled directly in the spot market without the customer taking on price risk for the whole site. 🏡 Small customers - Allowing a single retailer to create a secondary settlement point, without the need for a second physical connection to the distribution network, and assign it a different retail plan. For example, a retailer might offer discounted EV charging on a $/kWh basis if it can control charge operation.  We are yet to learn what value this adds compared to current arrangements whereby the retailer could offer the same discount ‘off market’. 🚗  Street furniture - Allowing measurement of energy flows using in-built technology (e.g. for pole mounted EV chargers). This is a very important change that could bring down the cost of low power AC public charging. While, these chargers typically have metering that with higher error bands, using native metering capability can result in capital savings, we think much greater than the system costs flowing from aggregate settlement error. Overall, the large customer and street furniture reforms offer benefits that seem clear and compelling. We are still reading the material , but have to ask: What are the new use cases for small customers created by the proposed changes ? Is this more a bone throw to AEMO’s desire for direct visibility of ‘the flex’? Read the AEMC material here: https://lnkd.in/ekd8UvNY

enX is thrilled to share our latest report for ARENA, exploring the transformative future potential of vehicle-to-grid (V2G) technology. This study unveils how innovative tariff arrangements can bolster V2G operations, offering significant benefits for EV owners and our electricity grid. We ran 520 customer V2G optimisation simulations under 6 different network and retail tariff scenarios (3120 total simulations) to compare the performance of different incentive arrangements. Key points: 🥇 Dynamic Tariffs: The study highlights the effectiveness of dynamic pricing (both network and wholesale energy) in maximising grid benefits and customer savings, and the comparative inefficiencies of current ToU tariff arrangements. ⚡ Grid Support: With dynamic tariffs and 10% penetration, V2G reduced substation critical peak demand by over 6%, enabling continuing load growth (electrification) without the need for ‘virtual power plants’ or ‘flexibility markets’. 💰 Bill Savings: On average, V2G users reduced their annual electricity bills by between $317 and $827 per year, compared to smart charging. V2G customers with low household energy usage can achieve net negative annual household bills under dynamic tariff arrangements. 📈 The electricity spot market can do much of the heavy lifting for networks during local critical peaks, but this can't always be relied on.
