The QSDEP is an average price series based on certain assumption, which complements the sales-based electricity cost data. The QSDEP indicator: 1. monitors tariffs. [pdf]
This works out to cost roughly $197 per month, if the current average kilowatt (kWh) price is 33.74 cents. It’s important to understand that different areas of the country have different rates for electricity. The below table shows some of the average rates around the country. Where is the most expensive place in New Zealand for power?
Canstar Blue reveals the average power bill in New Zealand and what you should be paying for power. Last year, the average Kiwi household used 7084kWh of electricity at 34.25c per kWh, for a total cost of $2426. This works out to roughly $202 per month.
residential costs back to the year ended March 2009 have been revised based on consistent information provided by all electricity retailers. Some retailers have also provided revised data back to the year ended March 2002. This has been incorporated into the residential electricity cost data.
The Ministry monitors national residential electricity costs using information about national electricity sales (essentially total electricity sales divided by the quantity of electricity supplied in kWh). Residential cost data is derived from information obtained primarily from electricity retailers.
It appears that Ashburton and Invercagill are the towns lucky to enjoy the lowest rates in the country. However, our largest cities, Wellington, Christchurch, and even Auckland appear to have lower rates than other smaller towns. It is likely that their denser population and wider spread out of power lines may help keep costs down.
The most recent stats show that, last year, the average Kiwi household used 7084kWh of electricity, at 34.25c per kWh, for a total cost of $2426. This works out to roughly $202 per month. Although most homes use more electricity over winter, and less in summer, due to heating costs.

The Brazil Energy Storage Market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030. .

Despite the benefits brought by ESS, the technology still has limited investment and application in Brazil. The financial viability of ESS, in the current Brazilian regulatory framework, is unlikely.
Some actions already implemented in the Brazilian electricity market, such as the hourly spot prices and the reduction of the minimum size required to access the free market, are considered necessary starting points in search of the economic viability of utility-scale ESS.
2.1. Energy storage systems (ESS) According to Shaqsi et al. , the demand for energy does not remain uniform throughout the day, nor throughout the year, but varies dramatically in one day and during the various seasons of the year.
In Germany, adding installations in operation and projects that are being implemented, the installed capacity in storage totals 13,517 MW, of which 406 MW are from ESS in batteries .
Depending on the characteristics of energy storage and discharge, an ESS can serve many functions in the electricity market. According to Ma et al. , the ESS in use for electrical energy generally includes the electrical, mechanical and electrochemical types.
Greater temporal granularity directly related to unrestricted access to the free market could enable the creation of a Brazilian energy stock exchange. Therefore, utility-scale ESS can be designed to operate with price arbitrage. In Brazil, it is necessary to create a capacity market in order to generate multiple revenues for utility-scale ESS.

Most of the renewable electricity generation (RES) plants in operation or under development already include battery energy storage (BESS) capacity. 11 contracts have already been signed for funding under the National Recovery and Resilience Plan (NRRP). 15 other projects will get financial support from the Modernisation Fund in the first quarter of this year, under a call for projects open until 17 February, with a total budget of 150 million euros.

Today, the Minister of Energy, Sebastian Burduja, announced on Facebook that an additional €150 million will be invested in Romania’s energy sector. "I am pleased to announce that the Ministry of Energy is launching a new call for projects financed through the Modernization Fund, aimed at investments in energy storage capacities (batteries).
The projects must focus on building new energy storage capacities in Romania," the minister stated. According to the minister, as quoted by ZF.ro, the total budget for this state aid scheme is €150 million in non-reimbursable funds sourced from the Modernization Fund.
Other Romania-based companies, such as Parapet and Waldevar Energy, have told pv magazine that adding BESS to their renewable assets is a top priority. The May edition of pv magazine features an in-depth look at Romania’s solar and energy storage markets.
At the beginning of 2025, Romania boasts approximately 3,000 MW in wind energy and 1,500 MW in solar energy. An additional 2,424 MW in wind and solar projects is expected to be operational in 2025, attracting over €2 billion in investments. Romania’s Energy Goals for 2030 Achieve over 32,000 MW in total capacity by 2030.
“As other European BESS markets become increasingly saturated, Romania stands out,” said Evangelos Gazis, Aurora’s head of Southeastern Europe, adding that the investment case for storage is strengthened by wind and solar’s rapid expansion driving high volatility in wholesale and balancing markets.

The BESS market in Romania is heating up, say local analysts and insiders. Irene Mihai, policy officer at the Romanian Photovoltaic Industry Association (RPIA) recently told pv magazine that a realistic target for the utility-scale BESS segment in Romania “would be around 2 GWh (around 1 GW of installed capacity)” for 2030.
